+## Requirements
+
+### Database User
+
+This source uses standard authentication. You will need to [create a CockroachDB user][crdb-users] to login to the database with. For CockroachDB Cloud deployments, SSL/TLS is required.
+
+[crdb-users]: https://www.cockroachlabs.com/docs/stable/create-user.html
+
+### SSL/TLS Configuration
+
+CockroachDB Cloud clusters require SSL/TLS connections. Use the `queryParams` section to configure SSL settings:
+
+- **For CockroachDB Cloud**: Use `sslmode: require` at minimum
+- **For self-hosted with certificates**: Use `sslmode: verify-full` with certificate paths
+- **For local development only**: Use `sslmode: disable` (not recommended for production)
+
+## Example
+
+```yaml
+sources:
+  my_cockroachdb:
+    type: cockroachdb
+    host: your-cluster.cockroachlabs.cloud
+    port: "26257"
+    user: myuser
+    password: mypassword
+    database: defaultdb
+    maxRetries: 5

+| `sslcert` | file path | Path to client certificate |
+| `sslkey` | file path | Path to client key |
+| `application_name` | string | Application name for connection tracking |
+
+## Best Practices
+
+### Security and MCP Compliance
+
+**Read-Only by Default**: The integration follows MCP best practices by defaulting to read-only mode. This prevents accidental data modifications:
+
+```yaml
+sources:
+  my_cockroachdb:
+    readOnlyMode: true        # Default behavior
+    enableWriteMode: false    # Explicit write opt-in required
+```
+
+To enable write operations:
+
+```yaml
+sources:
+  my_cockroachdb:
+    readOnlyMode: false       # Disable read-only protection
+    enableWriteMode: true     # Explicitly allow writes
+```
+
+**Query Limits**: Automatic row limits prevent excessive data retrieval:
+- SELECT queries automatically get `LIMIT 1000` appended (configurable via `maxRowLimit`)
+- Queries are terminated after 30 seconds (configurable via `queryTimeoutSec`)
+
+**Observability**: Structured telemetry provides visibility into tool usage:
+- Tool invocations are logged with status, latency, and row counts
+- SQL queries are redacted to protect sensitive values
+- Set `telemetryVerbose: true` for detailed JSON logs
+
+### Use UUID Primary Keys
+
+CockroachDB performs best with UUID primary keys rather than sequential integers to avoid transaction hotspots:
+
+```sql
+CREATE TABLE expenses (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  description TEXT,
+  amount DECIMAL(10,2)
+);
+```
+
+### Automatic Transaction Retry
+
+This source uses the official `cockroach-go/v2` library which provides automatic transaction retry for serialization conflicts. For write operations requiring explicit transaction control, tools can use the `ExecuteTxWithRetry` method.
+
+### Multi-Region Deployments
+
+CockroachDB supports multi-region deployments with automatic data distribution. Configure your cluster's regions and survival goals separately from the Toolbox configuration. The source will connect to any node in the cluster.
+
+### Connection Pooling
+
+The source maintains a connection pool to the CockroachDB cluster. The pool automatically handles:
+- Load balancing across cluster nodes
+- Connection retry with exponential backoff
+- Health checking of connections
+
+## Troubleshooting
+
+### SSL/TLS Errors
+
+If you encounter "server requires encryption" errors:
+
+1. For CockroachDB Cloud, ensure `sslmode` is set to `require` or higher:
+   ```yaml
+   queryParams:
+     sslmode: require
+   ```
+
+2. For certificate verification, download your cluster's root certificate and configure:
+   ```yaml
+   queryParams:
+     sslmode: verify-full
+     sslrootcert: /path/to/ca.crt
+   ```
+
+### Connection Timeouts
+
+If experiencing connection timeouts:
+
+1. Check network connectivity to the CockroachDB cluster
+2. Verify firewall rules allow connections on port 26257
+3. For CockroachDB Cloud, ensure IP allowlisting is configured
+4. Increase `maxRetries` or `retryBaseDelay` if needed
+
+### Transaction Retry Errors
+
+CockroachDB may encounter serializable transaction conflicts. The integration automatically handles these retries using the cockroach-go library. If you see retry-related errors, check:
+
+1. Database load and contention
+2. Query patterns that might cause conflicts
+3. Consider using `SELECT FOR UPDATE` for explicit locking

+  Execute ad-hoc SQL statements against a CockroachDB database.
+
+---
+
+## About
+
+A `cockroachdb-execute-sql` tool executes ad-hoc SQL statements against a CockroachDB database. This tool is designed for interactive workflows where the SQL query is provided dynamically at runtime, making it ideal for developer assistance and exploratory data analysis.
+
+The tool takes a single `sql` parameter containing the SQL statement to execute and returns the query results.
+
+> **Note:** This tool is intended for developer assistant workflows with human-in-the-loop and shouldn't be used for production agents. For production use cases with predefined queries, use [cockroachdb-sql](./cockroachdb-sql.md) instead.
+
+## Example
+
+```yaml
+sources:
+  my_cockroachdb:
+    type: cockroachdb
+    host: your-cluster.cockroachlabs.cloud
+    port: "26257"
+    user: myuser
+    password: mypassword
+    database: defaultdb
+    queryParams:
+      sslmode: require

+- **Syntax errors**: Invalid SQL syntax
+- **Permission errors**: Insufficient user privileges
+- **Connection errors**: Network or authentication issues
+- **Runtime errors**: Constraint violations, type mismatches, etc.
+
+## Security Considerations
+
+### SQL Injection Risk
+
+Since this tool executes arbitrary SQL, it should only be used with:
+- Trusted users in interactive sessions
+- Human-in-the-loop workflows
+- Development and testing environments
+
+Never expose this tool directly to end users without proper authorization controls.
+
+### Use Authentication
+
+Configure the `authRequired` field to restrict access:
+
+```yaml
+tools:
+  execute_sql:
+    type: cockroachdb-execute-sql
+    source: my_cockroachdb
+    description: Execute SQL statements
+    authRequired:
+      - my-auth-service
+```
+
+### Read-Only Users
+
+For safer exploration, create read-only database users:
+
+```sql
+CREATE USER readonly_user;
+GRANT SELECT ON DATABASE defaultdb TO readonly_user;
+```
+
+## Common Use Cases
+
+### Database Administration
+
+```sql
+-- View database size
+SELECT
+  table_name,
+  pg_size_pretty(pg_total_relation_size(table_name::regclass)) AS size
+FROM information_schema.tables
+WHERE table_schema = 'public'
+ORDER BY pg_total_relation_size(table_name::regclass) DESC;
+```
+
+### Performance Analysis
+
+```sql
+-- Find slow queries
+SELECT query, count, mean_latency
+FROM crdb_internal.statement_statistics
+WHERE mean_latency > INTERVAL '1 second'
+ORDER BY mean_latency DESC
+LIMIT 10;
+```
+
+### Data Quality Checks
+
+```sql
+-- Find NULL values
+SELECT COUNT(*) as null_count
+FROM expenses
+WHERE description IS NULL OR amount IS NULL;
+
+-- Find duplicates
+SELECT user_id, email, COUNT(*) as count
+FROM users
+GROUP BY user_id, email
+HAVING COUNT(*) > 1;
+```

+  List schemas in a CockroachDB database.
+
+---
+
+## About
+
+The `cockroachdb-list-schemas` tool retrieves a list of schemas (namespaces) in a CockroachDB database. Schemas are used to organize database objects such as tables, views, and functions into logical groups.
+
+This tool is useful for:
+- Understanding database organization
+- Discovering available schemas
+- Multi-tenant application analysis
+- Schema-level access control planning
+
+## Example
+
+```yaml
+sources:
+  my_cockroachdb:
+    type: cockroachdb
+    host: your-cluster.cockroachlabs.cloud
+    port: "26257"
+    user: myuser
+    password: mypassword
+    database: defaultdb
+    queryParams:
+      sslmode: require
+
+tools:
+  list_schemas:
+    type: cockroachdb-list-schemas
+    source: my_cockroachdb
+    description: List all schemas in the database
+```
+
+## Configuration
+
+### Required Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `type` | string | Must be `cockroachdb-list-schemas` |
+| `source` | string | Name of the CockroachDB source to use |
+| `description` | string | Human-readable description for the LLM |
+
+### Optional Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `authRequired` | array | List of authentication services required |
+
+## Output Structure
+
+The tool returns a list of schemas with the following information:
+
+```json
+[
+  {
+    "catalog_name": "defaultdb",
+    "schema_name": "public",
+    "is_user_defined": true
+  },
+  {
+    "catalog_name": "defaultdb",
+    "schema_name": "analytics",
+    "is_user_defined": true
+  }
+]
+```
+
+### Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `catalog_name` | string | The database (catalog) name |
+| `schema_name` | string | The schema name |
+| `is_user_defined` | boolean | Whether this is a user-created schema (excludes system schemas) |
+
+## Usage Example
+
+```json
+{}
+```
+
+No parameters are required. The tool automatically lists all user-defined schemas.
+
+## Default Schemas
+
+CockroachDB includes several standard schemas:
+
+- **`public`**: The default schema for user objects
+- **`pg_catalog`**: PostgreSQL system catalog (excluded from results)
+- **`information_schema`**: SQL standard metadata views (excluded from results)
+- **`crdb_internal`**: CockroachDB internal metadata (excluded from results)
+- **`pg_extension`**: PostgreSQL extension objects (excluded from results)
+
+The tool filters out system schemas and only returns user-defined schemas.
+
+## Schema Management in CockroachDB
+
+### Creating Schemas
+
+```sql
+CREATE SCHEMA analytics;
+```
+
+### Using Schemas
+
+```sql
+-- Create table in specific schema
+CREATE TABLE analytics.revenue (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  amount DECIMAL(10,2),
+  date DATE
+);
+
+-- Query from specific schema
+SELECT * FROM analytics.revenue;
+```
+
+### Schema Search Path
+
+The search path determines which schemas are searched for unqualified object names:
+
+```sql
+-- Show current search path
+SHOW search_path;
+
+-- Set search path
+SET search_path = analytics, public;
+```
+
+## Multi-Tenant Applications
+
+Schemas are commonly used for multi-tenant applications:
+
+```sql
+-- Create schema per tenant
+CREATE SCHEMA tenant_acme;
+CREATE SCHEMA tenant_globex;
+
+-- Create same table structure in each schema
+CREATE TABLE tenant_acme.orders (...);
+CREATE TABLE tenant_globex.orders (...);
+```
+
+The `cockroachdb-list-schemas` tool helps discover all tenant schemas:
+
+```yaml
+tools:
+  list_tenants:
+    type: cockroachdb-list-schemas
+    source: my_cockroachdb
+    description: |
+      List all tenant schemas in the database.
+      Each schema represents a separate tenant's data namespace.
+```
+
+## Best Practices
+
+### Use Schemas for Organization
+
+Group related tables into schemas:
+
+```sql
+CREATE SCHEMA sales;
+CREATE SCHEMA inventory;
+CREATE SCHEMA hr;
+
+CREATE TABLE sales.orders (...);
+CREATE TABLE inventory.products (...);
+CREATE TABLE hr.employees (...);
+```
+
+### Schema Naming Conventions
+
+Use clear, descriptive schema names:
+- Lowercase names
+- Use underscores for multi-word names
+- Avoid reserved keywords
+- Use prefixes for grouped schemas (e.g., `tenant_`, `app_`)
+
+### Schema-Level Permissions
+
+Schemas enable fine-grained access control:
+
+```sql
+-- Grant access to specific schema
+GRANT USAGE ON SCHEMA analytics TO analyst_role;
+GRANT SELECT ON ALL TABLES IN SCHEMA analytics TO analyst_role;
+
+-- Revoke access
+REVOKE ALL ON SCHEMA hr FROM public;
+```
+
+## Integration with Other Tools
+
+### Combined with List Tables
+
+```yaml
+tools:
+  list_schemas:
+    type: cockroachdb-list-schemas
+    source: my_cockroachdb
+    description: List all schemas first
+    
+  list_tables:
+    type: cockroachdb-list-tables
+    source: my_cockroachdb
+    description: |
+      List tables in the database.
+      Use list_schemas first to understand schema organization.
+```
+
+### Schema Discovery Workflow
+
+1. Call `cockroachdb-list-schemas` to discover schemas
+2. Call `cockroachdb-list-tables` to see tables in each schema
+3. Generate queries using fully qualified names: `schema.table`
+
+## Common Use Cases
+
+### Discover Database Structure
+
+```yaml
+tools:
+  discover_schemas:
+    type: cockroachdb-list-schemas
+    source: my_cockroachdb
+    description: |
+      Discover how the database is organized into schemas.
+      Use this to understand the logical grouping of tables.
+```
+
+### Multi-Tenant Analysis
+
+```yaml
+tools:
+  list_tenant_schemas:
+    type: cockroachdb-list-schemas
+    source: my_cockroachdb
+    description: |
+      List all tenant schemas (each tenant has their own schema).
+      Schema names follow the pattern: tenant_<company_name>
+```
+
+### Schema Migration Planning
+
+```yaml
+tools:
+  audit_schemas:
+    type: cockroachdb-list-schemas
+    source: my_cockroachdb
+    description: |
+      Audit existing schemas before migration.
+      Identifies all schemas that need to be migrated.
+```
+
+## Error Handling
+
+The tool handles common errors:
+- **Connection errors**: Returns connection failure details
+- **Permission errors**: Returns error if user lacks USAGE privilege
+- **Empty results**: Returns empty array if no user schemas exist
+
+## Permissions Required
+
+To list schemas, the user needs:
+- `CONNECT` privilege on the database
+- No specific schema privileges required for listing
+
+To query objects within schemas, the user needs:
+- `USAGE` privilege on the schema
+- Appropriate object privileges (SELECT, INSERT, etc.)
+
+## CockroachDB-Specific Features
+
+### System Schemas
+
+CockroachDB includes PostgreSQL-compatible system schemas plus CockroachDB-specific ones:
+
+- `crdb_internal.*`: CockroachDB internal metadata and statistics
+- `pg_catalog.*`: PostgreSQL system catalog
+- `information_schema.*`: SQL standard information schema
+
+These are automatically filtered from the results.
+
+### User-Defined Flag
+
+The `is_user_defined` field helps distinguish:
+- `true`: User-created schemas
+- `false`: System schemas (already filtered out)

+}
+```
+
+## CockroachDB-Specific Information
+
+### UUID Primary Keys
+
+The tool recognizes CockroachDB's recommended UUID primary key pattern:
+
+```sql
+CREATE TABLE users (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  ...
+);
+```
+
+### Multi-Region Tables
+
+For multi-region tables, the output includes locality information:
+
+```json
+{
+  "table_name": "users",
+  "locality": "REGIONAL BY ROW",
+  "regions": ["us-east-1", "us-west-2", "eu-west-1"]
+}
+```
+
+### Interleaved Tables
+
+The tool shows parent-child relationships for interleaved tables (legacy feature):
+
+```json
+{
+  "table_name": "order_items",
+  "interleaved_in": "orders"
+}
+```
+
+## Best Practices
+
+### Use for Schema Discovery
+
+The tool is ideal for helping AI assistants understand your database structure:
+
+```yaml
+tools:
+  discover_schema:
+    type: cockroachdb-list-tables
+    source: my_cockroachdb
+    description: |
+      Use this tool first to understand the database schema before generating queries.
+      It shows all tables, their columns, data types, and relationships.
+```
+
+### Filter Large Schemas
+
+For databases with many tables, specify relevant tables:
+
+```json
+{
+  "table_names": ["users", "orders", "products"],
+  "output_format": "detailed"
+}
+```
+
+### Use Simple Format for Overviews
+
+When you need just table names and sizes:
+
+```json
+{
+  "output_format": "simple"
+}
+```
+
+## Excluded Tables
+
+The tool automatically excludes system tables and schemas:
+- `pg_catalog.*` - PostgreSQL system catalog
+- `information_schema.*` - SQL standard information schema
+- `crdb_internal.*` - CockroachDB internal tables
+- `pg_extension.*` - PostgreSQL extension tables
+
+Only user-created tables in the public schema (and other user schemas) are returned.
+
+## Error Handling
+
+The tool handles common errors:
+- **Table not found**: Returns empty result for non-existent tables
+- **Permission errors**: Returns error if user lacks SELECT privileges
+- **Connection errors**: Returns connection failure details
+
+## Integration with AI Assistants
+
+### Prompt Example
+
+```yaml
+tools:
+  list_tables:
+    type: cockroachdb-list-tables
+    source: my_cockroachdb
+    description: |
+      Lists all tables in the database with detailed schema information.
+      Use this tool to understand:
+      - What tables exist
+      - What columns each table has
+      - Data types and constraints
+      - Relationships between tables (foreign keys)
+      - Available indexes
+      
+      Always call this tool before generating SQL queries to ensure
+      you use correct table and column names.
+```
+
+## Common Use Cases
+
+### Generate Context for Queries
+
+```json
+{}
+```
+
+This provides comprehensive schema information that helps AI assistants generate accurate SQL queries.
+
+### Analyze Table Structure
+
+```json
+{
+  "table_names": ["users"],
+  "output_format": "detailed"
+}
+```
+
+Perfect for understanding a specific table's structure, constraints, and relationships.
+
+### Quick Schema Overview
+
+```json
+{
+  "output_format": "simple"
+}
+```
+
+Gets a quick list of tables with basic statistics.
+
+## Performance Considerations
+
+- **Simple format** is faster for large databases
+- **Detailed format** queries system tables extensively
+- Specifying `table_names` reduces query time
+- Results are fetched in a single query for efficiency

+  Execute parameterized SQL queries in CockroachDB.
+
+---
+
+## About
+
+The `cockroachdb-sql` tool allows you to execute parameterized SQL queries against a CockroachDB database. This tool supports prepared statements with parameter binding, template parameters for dynamic query construction, and automatic transaction retry for resilience against serialization conflicts.
+
+## Example
+
+```yaml
+sources:
+  my_cockroachdb:
+    type: cockroachdb
+    host: your-cluster.cockroachlabs.cloud
+    port: "26257"
+    user: myuser
+    password: mypassword
+    database: defaultdb
+    queryParams:
+      sslmode: require
+
+tools:
+  get_user_orders:
+    type: cockroachdb-sql
+    source: my_cockroachdb
+    description: Get all orders for a specific user
+    statement: |
+      SELECT o.id, o.order_date, o.total_amount, o.status
+      FROM orders o
+      WHERE o.user_id = $1
+      ORDER BY o.order_date DESC
+    parameters:
+      - name: user_id
+        type: string
+        description: The UUID of the user
+```
+
+## Configuration
+
+### Required Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `type` | string | Must be `cockroachdb-sql` |
+| `source` | string | Name of the CockroachDB source to use |
+| `description` | string | Human-readable description of what the tool does |
+| `statement` | string | The SQL query to execute |
+
+### Optional Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `parameters` | array | List of parameter definitions for the query |
+| `templateParameters` | array | List of template parameters for dynamic query construction |
+| `authRequired` | array | List of authentication services required |
+
+## Parameters
+
+Parameters allow you to safely pass values into your SQL queries using prepared statements. CockroachDB uses PostgreSQL-style parameter placeholders: `$1`, `$2`, etc.
+
+### Parameter Types
+
+- `string`: Text values
+- `number`: Numeric values (integers or decimals)
+- `boolean`: True/false values
+- `array`: Array of values
+
+### Example with Multiple Parameters
+
+```yaml
+tools:
+  filter_expenses:
+    type: cockroachdb-sql
+    source: my_cockroachdb
+    description: Filter expenses by category and date range
+    statement: |
+      SELECT id, description, amount, category, expense_date
+      FROM expenses
+      WHERE user_id = $1
+        AND category = $2
+        AND expense_date >= $3
+        AND expense_date <= $4
+      ORDER BY expense_date DESC
+    parameters:
+      - name: user_id
+        type: string
+        description: The user's UUID
+      - name: category
+        type: string
+        description: Expense category (e.g., "Food", "Transport")
+      - name: start_date
+        type: string
+        description: Start date in YYYY-MM-DD format
+      - name: end_date
+        type: string
+        description: End date in YYYY-MM-DD format
+```
+
+## Template Parameters
+
+Template parameters enable dynamic query construction by replacing placeholders in the SQL statement before parameter binding. This is useful for dynamic table names, column names, or query structure.
+
+### Example with Template Parameters
+
+```yaml
+tools:
+  get_column_data:
+    type: cockroachdb-sql
+    source: my_cockroachdb
+    description: Get data from a specific column
+    statement: |
+      SELECT {{column_name}}
+      FROM {{table_name}}
+      WHERE user_id = $1
+      LIMIT 100
+    templateParameters:
+      - name: table_name
+        type: string
+        description: The table to query
+      - name: column_name
+        type: string
+        description: The column to retrieve
+    parameters:
+      - name: user_id
+        type: string
+        description: The user's UUID
+```
+
+## Best Practices
+
+### Use UUID Primary Keys
+
+CockroachDB performs best with UUID primary keys to avoid transaction hotspots:
+
+```sql
+CREATE TABLE orders (
+  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
+  user_id UUID NOT NULL,
+  order_date TIMESTAMP DEFAULT now(),
+  total_amount DECIMAL(10,2)
+);
+```
+
+### Use Indexes for Performance
+
+Create indexes on frequently queried columns:
+
+```sql
+CREATE INDEX idx_orders_user_id ON orders(user_id);
+CREATE INDEX idx_orders_date ON orders(order_date DESC);
+```
+
+### Use JOINs Efficiently
+
+CockroachDB supports standard SQL JOINs. Keep joins efficient by:
+- Adding appropriate indexes
+- Using UUIDs for foreign keys
+- Limiting result sets with WHERE clauses
+
+```yaml

@@ -50,5 +50,30 @@ It is helpful to understand how tool-level processing differs from other scopes:
 - **Model Level**: Intercepts individual calls to the LLM (prompts and responses). Unlike tool-level, this applies globally to all text sent/received, making it better for global PII redaction or token tracking.
 - **Agent Level**: Wraps the high-level execution loop (e.g., a "turn" in the conversation). Unlike tool-level, this envelopes the entire turn (user input to final response), making it suitable for session management or end-to-end auditing.
 
+## Best Practices
+
+### Security & Guardrails
+
+- **Principle of Least Privilege**: Ensure that tools run with the minimum necessary permissions. Middleware is an excellent place to enforce "read-only" modes or verify user identity before executing sensitive actions.
+- **Input Sanitization**: Actively strip potential PII (like credit card numbers or raw emails) from tool arguments before logging them.
+- **Prompt Injection Defense**: Use pre-processing hooks to scan user inputs for known jailbreak patterns or malicious directives before they reach the model or tools.
+
+### Observability & Debugging
+
+- **Structured Logging**: Instead of simple print statements, use structured JSON logging with correlation IDs. This allows you to trace a single user request through multiple agent turns and tool calls.
+- **Logging for Testability**: LLM responses are non-deterministic and may summarize away key details.
+  - **Pattern**: Add explicit logging markers in your post-processing middleware (e.g., `logger.info("ACTION_SUCCESS: <id>")`).
+  - **Benefit**: Your integration tests can grep logs for these stable markers to verify tool success, rather than painfully parsing variable natural language responses.
+
+### Performance & Cost Optimization
+
+- **Token Economy**: Tools often return verbose JSON. Use post-processing to strip unnecessary fields or summarize large datasets *before* returning the result to the LLM's context window. This saves tokens and reduces latency.
+- **Caching**: For read-heavy tools (like "search_knowledge_base"), implement caching middleware to return previous results for identical queries, saving both time and API costs.
+
+### Error Handling
+
+- **Graceful Degradation**: If a tool fails (e.g., API timeout), catch the exception in middleware and return a structured error message to the LLM (e.g., `Error: Database timeout, please try again`).
+- **Self-Correction**: Well-formatted error messages often allow the LLM to understand *why* a call failed and retry it with corrected parameters automatically.

+  How to add pre- and post- processing to your Agents using Go.
+---
+
+## Prerequisites
+
+This tutorial assumes that you have set up MCP Toolbox with a basic agent as described in the [local quickstart](../../getting-started/local_quickstart_go.md).
+
+This guide demonstrates how to implement these patterns in your Toolbox applications.
+
+## Implementation
+
+{{< tabpane persist=header >}}
+{{% tab header="ADK" text=true %}}
+The following example demonstrates how to use the `beforeToolCallback` and `afterToolCallback` hooks in the ADK `LlmAgent` to implement pre and post processing logic.
+
+```go
+{{< include "go/adk/agent.go" >}}
+```
+
+You can also add model-level (`beforeModelCallback`, `afterModelCallback`) and agent-level (`beforeAgentCallback`, `afterAgentCallback`) hooks to intercept messages at different stages of the execution loop.
+
+For more information, see the [ADK Callbacks documentation](https://google.github.io/adk-docs/callbacks/types-of-callbacks/).{{% /tab %}}
+{{< /tabpane >}}
+
+## Results
+
+The output should look similar to the following.
+
+{{< notice note >}}
+The exact responses may vary due to the non-deterministic nature of LLMs and differences between orchestration frameworks.
+{{< /notice >}}
+
+```
+AI: Booking Confirmed! You earned 500 Loyalty Points with this stay.
+
+AI: Error: Maximum stay duration is 14 days.

+  How to add pre- and post- processing to your Agents using JS.
+---
+
+## Prerequisites
+
+This tutorial assumes that you have set up MCP Toolbox with a basic agent as described in the [local quickstart](../../getting-started/local_quickstart_js.md).
+
+This guide demonstrates how to implement these patterns in your Toolbox applications.
+
+## Implementation
+
+{{< tabpane persist=header >}}
+{{% tab header="ADK" text=true %}}
+Coming soon.
+{{% /tab %}}
+{{% tab header="Langchain" text=true %}}
+The following example demonstrates how to use `ToolboxClient` with LangChain's middleware to implement pre- and post- processing for tool calls.
+
+```js
+{{< include "js/langchain/agent.js" >}}
+```
+
+You can also use the `wrapModelCall` hook to intercept messages before and after model calls.
+You can also use [node-style hooks](https://docs.langchain.com/oss/javascript/langchain/middleware/custom#node-style-hooks) to intercept messages at the agent and model level.
+See the [LangChain Middleware documentation](https://docs.langchain.com/oss/javascript/langchain/middleware/custom#tool-call-monitoring) for details on these additional hook types.

-## Overview
-
-The MCP Toolbox service provides a centralized way to manage and expose tools
-(like API connectors, database query tools, etc.) for use by GenAI applications.
-
-The Go SDK act as clients for that service. They handle the communication needed to:
-
-* Fetch tool definitions from your running Toolbox instance.
-* Provide convenient Go structs representing those tools.
-* Invoke the tools (calling the underlying APIs/services configured in Toolbox).
-* Handle authentication and parameter binding as needed.
-
-By using the SDK, you can easily leverage your Toolbox-managed tools directly
-within your Go applications or AI orchestration frameworks.
-
-## Which Package Should I Use?
-
-Choosing the right package depends on how you are building your application:
-
-- [**`core`**](core/):
-  This is a framework-agnostic way to connect tools to popular frameworks
-  like Google GenAI, LangChain, etc.
-
-- [**`tbadk`**](tbadk/):
-  This package provides a way to connect tools to ADK Go.
-
-- [**`tbgenkit`**](tbgenkit/):
-  This package provides functionality to convert the Tool fetched using the core package
-  into a Genkit Go compatible tool.
-
-## Available Packages
-
-This repository hosts the following Go packages. See the package-specific
-README for detailed installation and usage instructions:
-
-| Package | Target Use Case | Integration | Path | Details (README) |
-| :------ | :----------| :---------- | :---------------------- | :---------- |
-| [`core`](core/) | Framework-agnostic / Custom applications | Use directly / Custom | `core/` | 📄 [View README](https://github.com/googleapis/mcp-toolbox-sdk-go/blob/main/core/README.md) |
-| [`tbadk`](tbadk/) | ADK Go | Use directly | `tbadk/` | 📄 [View README](https://github.com/googleapis/mcp-toolbox-sdk-go/blob/main/tbadk/README.md) |
-| [`tbgenkit`](tbgenkit/) | Genkit Go | Along with core | `tbgenkit/` | 📄 [View README](https://github.com/googleapis/mcp-toolbox-sdk-go/blob/main/tbgenkit/README.md) |
-
-## Getting Started
-
-To get started using Toolbox tools with an application, follow these general steps:
-
-1. **Set up and Run the Toolbox Service:**
-
-    Before using the SDKs, you need the MCP Toolbox server running. Follow
-    the instructions here: [**Toolbox Getting Started
-    Guide**](https://github.com/googleapis/genai-toolbox?tab=readme-ov-file#getting-started)
-
-2. **Install the Appropriate SDK:**
-
-    Choose the package based on your needs (see "[Which Package Should I Use?](#which-package-should-i-use)" above)
-    Use this command to install the SDK module
-
-    ```bash
-    # For the core, framework-agnostic SDK
-    go get github.com/googleapis/mcp-toolbox-sdk-go
-    ```
-
-3. **Use the SDK:**
-
-    Consult the `README` for your chosen package (linked in the "[Available
-    Packages](#available-packages)" section above) for detailed instructions on
-    how to connect the client, load tool definitions, invoke tools, configure
-    authentication/binding, and integrate them into your application or
-    framework.

-
-[![License: Apache 2.0](https://img.shields.io/badge/License-Apache%202.0-blue.svg)](https://opensource.org/licenses/Apache-2.0)
-
-This SDK allows you to seamlessly integrate the functionalities of
-[MCP Toolbox](https://github.com/googleapis/genai-toolbox) allowing you to load and
-use tools defined in the service as standard Go structs within your GenAI
-applications.
-
-This simplifies integrating external functionalities (like APIs, databases, or
-custom logic) managed by the Toolbox into your workflows, especially those
-involving Large Language Models (LLMs).
-
-## Installation
-
-```bash
-go get github.com/googleapis/mcp-toolbox-sdk-go
-```
-This SDK is supported on Go version 1.24.4 and higher.
-
-{{< notice note >}}
-While the SDK itself is synchronous, you can execute its functions within goroutines to achieve asynchronous behavior.
-{{< /notice >}}
-
-
-## Quickstart
-
-Here's a minimal example to get you started. Ensure your Toolbox service is
-running and accessible.
-
-```go
-package main
-
-import (
-	"context"
-	"fmt"
-	"github.com/googleapis/mcp-toolbox-sdk-go/core"
-)
-
-func quickstart() string {
-	ctx := context.Background()
-	inputs := map[string]any{"location": "London"}
-	client, err := core.NewToolboxClient("http://localhost:5000")
-	if err != nil {
-		return fmt.Sprintln("Could not start Toolbox Client", err)
-	}
-	tool, err := client.LoadTool("get_weather", ctx)
-	if err != nil {
-		return fmt.Sprintln("Could not load Toolbox Tool", err)
-	}
-	result, err := tool.Invoke(ctx, inputs)
-	if err != nil {
-		return fmt.Sprintln("Could not invoke tool", err)
-	}
-	return fmt.Sprintln(result)
-}
-
-func main() {
-	fmt.Println(quickstart())
-}
-```
-
-## Usage
-
-Import and initialize a Toolbox client, pointing it to the URL of your running
-Toolbox service.
-
-```go
-import "github.com/googleapis/mcp-toolbox-sdk-go/core"
-
-client, err := core.NewToolboxClient("http://localhost:5000")
-```
-
-All interactions for loading and invoking tools happen through this client.
-
-{{< notice note >}} 
-For advanced use cases, you can provide an external custom `http.Client` during initialization (e.g., `core.NewToolboxClient(URL, core.WithHTTPClient(myClient)`). 
-If you provide your own session, you are responsible for managing its lifecycle; `ToolboxClient` *will not* close it.
-{{< /notice >}}
-
-{{< notice info >}}
-Closing the `ToolboxClient` also closes the underlying network session shared by all tools loaded from that client. As a result, any tool instances you have loaded will cease to function and will raise an error if you attempt to invoke them after the client is closed.
-{{< /notice >}}
-
-## Transport Protocols
-
-The SDK supports multiple transport protocols for communicating with the Toolbox server. By default, the client uses the latest supported version of the **Model Context Protocol (MCP)**.
-
-You can explicitly select a protocol using the `core.WithProtocol` option during client initialization. This is useful if you need to use the native Toolbox HTTP protocol or pin the client to a specific legacy version of MCP.
-
-{{< notice note >}}
-* **Native Toolbox Transport**: This uses the service's native **REST over HTTP** API.
-* **MCP Transports**: These options use the **Model Context Protocol over HTTP**.
-{{< /notice >}}
-
-
-### Supported Protocols
-
-| Constant | Description |
-| :--- | :--- |
-| `core.MCP` | **(Default)** Alias for the latest supported MCP version (currently `v2025-06-18`). |
-| `core.Toolbox` | The native Toolbox HTTP protocol. |
-| `core.MCPv20250618` | MCP Protocol version 2025-06-18. |
-| `core.MCPv20250326` | MCP Protocol version 2025-03-26. |
-| `core.MCPv20241105` | MCP Protocol version 2024-11-05. |
-
-### Example
-
-If you wish to use the native Toolbox protocol:
-
-```go
-import "github.com/googleapis/mcp-toolbox-sdk-go/core"
-
-client, err := core.NewToolboxClient(
-    "http://localhost:5000",
-    core.WithProtocol(core.Toolbox),
-)
-```
-If you want to pin the MCP Version 2025-03-26:
-
-```go
-import "github.com/googleapis/mcp-toolbox-sdk-go/core"
-
-client, err := core.NewToolboxClient(
-    "http://localhost:5000",
-    core.WithProtocol(core.MCPv20250326),
-)
-```
-
-## Loading Tools
-
-You can load tools individually or in groups (toolsets) as defined in your
-Toolbox service configuration. Loading a toolset is convenient when working with
-multiple related functions, while loading a single tool offers more granular
-control.
-
-### Load a toolset
-
-A toolset is a collection of related tools. You can load all tools in a toolset
-or a specific one:
-
-```go
-// Load default toolset by providing an empty string as the name
-tools, err := client.LoadToolset("", ctx)
-
-// Load a specific toolset
-tools, err := client.LoadToolset("my-toolset", ctx)
-```
-
-
-### Load a single tool
-
-Loads a specific tool by its unique name. This provides fine-grained control.
-
-```go
-tool, err = client.LoadTool("my-tool", ctx)
-```
-
-## Invoking Tools
-
-Once loaded, tools behave like Go structs. You invoke them using `Invoke` method
-by passing arguments corresponding to the parameters defined in the tool's
-configuration within the Toolbox service.
-
-```go
-tool, err = client.LoadTool("my-tool", ctx)
-inputs := map[string]any{"location": "London"}
-result, err := tool.Invoke(ctx, inputs)
-```
-
-{{< notice tip >}}
-For a more comprehensive guide on setting up the Toolbox service itself, which you'll need running to use this SDK, please refer to the [Toolbox Quickstart Guide](https://googleapis.github.io/genai-toolbox/getting-started/local_quickstart).
-{{< /notice >}}
-
-## Client to Server Authentication
-
-This section describes how to authenticate the ToolboxClient itself when
-connecting to a Toolbox server instance that requires authentication. This is
-crucial for securing your Toolbox server endpoint, especially when deployed on
-platforms like Cloud Run, GKE,  or any environment where unauthenticated access is restricted.
-
-This client-to-server authentication ensures that the Toolbox server can verify
-the identity of the client making the request before any tool is loaded or
-called. It is different from [Authenticating Tools](#authenticating-tools),
-which deals with providing credentials for specific tools within an already
-connected Toolbox session.
-
-### When is Client-to-Server Authentication Needed?
-
-You'll need this type of authentication if your Toolbox server is configured to
-deny unauthenticated requests. For example:
-
-- Your Toolbox server is deployed on Cloud Run and configured to "Require authentication."
-- Your server is behind an Identity-Aware Proxy (IAP) or a similar
-  authentication layer.
-- You have custom authentication middleware on your self-hosted Toolbox server.
-
-Without proper client authentication in these scenarios, attempts to connect or
-make calls (like `LoadTool`) will likely fail with `Unauthorized` errors.
-
-### How it works
-
-The `ToolboxClient` allows you to specify TokenSources that dynamically generate HTTP headers for
-every request sent to the Toolbox server. The most common use case is to add an
-Authorization header with a bearer token (e.g., a Google ID token).
-
-These header-generating functions are called just before each request, ensuring
-that fresh credentials or header values can be used.
-
-### Configuration
-
-You can configure these dynamic headers as seen below:
-
-
-```go
-import "github.com/googleapis/mcp-toolbox-sdk-go/core"
-
-tokenProvider := func() string {
-	return "header3_value"
-}

-### Authenticating with Google Cloud Servers
-
-For Toolbox servers hosted on Google Cloud (e.g., Cloud Run) and requiring
-`Google ID token` authentication, the helper module
-[auth_methods](https://github.com/googleapis/mcp-toolbox-sdk-go/blob/main/core/auth.go) provides utility functions.
-
-### Step by Step Guide for Cloud Run
-
-1. **Configure Permissions**: [Grant](https://cloud.google.com/run/docs/securing/managing-access#service-add-principals) the `roles/run.invoker` IAM role on the Cloud
-   Run service to the principal. This could be your `user account email` or a
-   `service account`.
-2. **Configure Credentials**
-    - Local Development: Set up
-   [ADC](https://cloud.google.com/docs/authentication/set-up-adc-local-dev-environment).
-    - Google Cloud Environments: When running within Google Cloud (e.g., Compute
-      Engine, GKE, another Cloud Run service, Cloud Functions), ADC is typically
-      configured automatically, using the environment's default service account.
-3. **Connect to the Toolbox Server**
-    ```go
-    import "github.com/googleapis/mcp-toolbox-sdk-go/core"
-    import "context"
-
-    ctx := context.Background()
-
-    token, err := core.GetGoogleIDToken(ctx, URL)
-
-    client, err := core.NewToolboxClient(
-      URL,
-      core.WithClientHeaderString("Authorization", token),
-    )
-
-    // Now, you can use the client as usual.
-    ```
-
-## Authenticating Tools
-
-{{< notice warning >}}
-**Always use HTTPS** to connect your application with the Toolbox service, especially in **production environments** or whenever the communication involves **sensitive data** (including scenarios where tools requireauthentication tokens). Using plain HTTP lacks encryption and exposes your application and data to significant security risks, such as eavesdropping and tampering.
-{{< /notice >}}
-
-Tools can be configured within the Toolbox service to require authentication,
-ensuring only authorized users or applications can invoke them, especially when
-accessing sensitive data.
-
-### When is Authentication Needed?
-
-Authentication is configured per-tool within the Toolbox service itself. If a
-tool you intend to use is marked as requiring authentication in the service, you
-must configure the SDK client to provide the necessary credentials (currently
-Oauth2 tokens) when invoking that specific tool.
-
-### Supported Authentication Mechanisms
-
-The Toolbox service enables secure tool usage through **Authenticated Parameters**.
-For detailed information on how these mechanisms work within the Toolbox service and how to configure them, please refer to [Toolbox Service Documentation - Authenticated Parameters](https://googleapis.github.io/genai-toolbox/resources/tools/#authenticated-parameters).
-
-### Step 1: Configure Tools in Toolbox Service
-
-First, ensure the target tool(s) are configured correctly in the Toolbox service
-to require authentication. Refer to the [Toolbox Service Documentation -
-Authenticated
-Parameters](https://googleapis.github.io/genai-toolbox/resources/tools/#authenticated-parameters)
-for instructions.
-
-### Step 2: Configure SDK Client
-
-Your application needs a way to obtain the required Oauth2 token for the
-authenticated user. The SDK requires you to provide a function capable of
-retrieving this token *when the tool is invoked*.
-
-#### Provide an ID Token Retriever Function
-
-You must provide the SDK with a function that returns the
-necessary token when called. The implementation depends on your application's
-authentication flow (e.g., retrieving a stored token, initiating an OAuth flow).
-
-{{< notice info >}}
-The name used when registering the getter function with the SDK (e.g., `"my_api_token"`) must exactly match the `name` of the corresponding `authServices` defined in the tool's configuration within the Toolbox service.
-{{< /notice >}}
-
-```go
-func getAuthToken() string {
-  // ... Logic to retrieve ID token (e.g., from local storage, OAuth flow)
-  // This example just returns a placeholder. Replace with your actual token retrieval.
-	return "YOUR_ID_TOKEN" // Placeholder
-}
-```
-
-{{< notice tip >}}
-Your token retriever function is invoked every time an authenticated parameter requires a token for a tool call. Consider implementing caching logic within this function to avoid redundant token fetching or generation, especially for tokens with longer validity periods or if the retrieval process is resource-intensive.
-{{< /notice >}}
-
-#### Option A: Add Default Authentication to a Client
-
-You can add default tool level authentication to a client.
-Every tool / toolset loaded by the client will contain the auth token.
-
-```go
-
-ctx := context.Background()
-
-client, err := core.NewToolboxClient("http://127.0.0.1:5000",
-	core.WithDefaultToolOptions(
-		core.WithAuthTokenString("my-auth-1", "auth-value"),
-	),
-)
-
-AuthTool, err := client.LoadTool("my-tool", ctx)
-```
-
-#### Option B: Add Authentication to a Loaded Tool
-
-You can add the token retriever function to a tool object *after* it has been
-loaded. This modifies the specific tool instance.
-
-```go
-
-ctx := context.Background()
-
-client, err := core.NewToolboxClient("http://127.0.0.1:5000")
-
-tool, err := client.LoadTool("my-tool", ctx)
-
-AuthTool, err := tool.ToolFrom(
-  core.WithAuthTokenSource("my-auth", headerTokenSource),
-  core.WithAuthTokenString("my-auth-1", "value"),
-  )
-```
-
-#### Option C: Add Authentication While Loading Tools
-
-You can provide the token retriever(s) directly during the `LoadTool` or
-`LoadToolset` calls. This applies the authentication configuration only to the
-tools loaded in that specific call, without modifying the original tool objects
-if they were loaded previously.
-
-```go
-AuthTool, err := client.LoadTool("my-tool", ctx, core.WithAuthTokenString("my-auth-1", "value"))
-
-// or
-
-AuthTools, err := client.LoadToolset(
-  "my-toolset",
-  ctx,
-  core.WithAuthTokenString("my-auth-1", "value"),
-)
-```
-
-{{< notice note >}}
-Adding auth tokens during loading only affect the tools loaded within that call.
-{{< /notice >}}
-
-### Complete Authentication Example
-
-```go
-import "github.com/googleapis/mcp-toolbox-sdk-go/core"
-import "fmt"
-
-func getAuthToken() string {
-  // ... Logic to retrieve ID token (e.g., from local storage, OAuth flow)
-  // This example just returns a placeholder. Replace with your actual token retrieval.
-	return "YOUR_ID_TOKEN" // Placeholder
-}
-
-func main() {
-  ctx := context.Background()
-  inputs := map[string]any{"input": "some input"}
-
-  dynamicTokenSource := core.NewCustomTokenSource(getAuthToken)
-
-  client, err := core.NewToolboxClient("http://127.0.0.1:5000")
-  tool, err := client.LoadTool("my-tool", ctx)
-  AuthTool, err := tool.ToolFrom(core.WithAuthTokenSource("my_auth", dynamicTokenSource))
-
-  result, err := AuthTool.Invoke(ctx, inputs)
-
-  fmt.Println(result)
-}
-```
-
-{{< notice note >}}
-An auth token getter for a specific name (e.g., "GOOGLE_ID") will replace any client header with the same name followed by "_token" (e.g., "GOOGLE_ID_token").
-{{< /notice >}}
-
-## Binding Parameter Values
-
-The SDK allows you to pre-set, or "bind", values for specific tool parameters
-before the tool is invoked or even passed to an LLM. These bound values are
-fixed and will not be requested or modified by the LLM during tool use.
-
-### Why Bind Parameters?
-
-- **Protecting sensitive information:**  API keys, secrets, etc.
-- **Enforcing consistency:** Ensuring specific values for certain parameters.
-- **Pre-filling known data:**  Providing defaults or context.
-
-{{< notice info >}}
-The parameter names used for binding (e.g., `"api_key"`) must exactly match the parameter names defined in the tool's configuration within the Toolbox service.
-{{< /notice >}}
-
-{{< notice note >}}
-You do not need to modify the tool's configuration in the Toolbox service to bind parameter values using the SDK.
-{{< /notice >}}
-
-#### Option A: Add Default Bound Parameters to a Client
-
-You can add default tool level bound parameters to a client. Every tool / toolset  
-loaded by the client will have the bound parameter.
-
-```go
-
-ctx := context.Background()
-
-client, err := core.NewToolboxClient("http://127.0.0.1:5000",
-	core.WithDefaultToolOptions(
-		core.WithBindParamString("param1", "value"),
-	),
-)
-
-boundTool, err := client.LoadTool("my-tool", ctx)
-```
-
-### Option B: Binding Parameters to a Loaded Tool
-
-Bind values to a tool object *after* it has been loaded. This modifies the
-specific tool instance.
-
-```go
-client, err := core.NewToolboxClient("http://127.0.0.1:5000")
-
-tool, err := client.LoadTool("my-tool", ctx)
-
-boundTool, err := tool.ToolFrom(
-  core.WithBindParamString("param1", "value"),
-  core.WithBindParamString("param2", "value")
-  )
-```
-
-### Option C: Binding Parameters While Loading Tools
-
-Specify bound parameters directly when loading tools. This applies the binding
-only to the tools loaded in that specific call.
-
-```go
-boundTool, err := client.LoadTool("my-tool", ctx, core.WithBindParamString("param", "value"))
-
-// OR
-
-boundTool, err := client.LoadToolset("", ctx, core.WithBindParamString("param", "value"))
-```
-
-{{< notice note >}} Bound values during loading only affect the tools loaded in that call. {{< /notice >}}
-
-### Binding Dynamic Values
-
-Instead of a static value, you can bind a parameter to a synchronous or
-asynchronous function. This function will be called *each time* the tool is
-invoked to dynamically determine the parameter's value at runtime.
-Functions with the return type (data_type, error) can be provided.
-
-```go
-getDynamicValue := func() (string, error) { return "req-123", nil }
-
-dynamicBoundTool, err := tool.ToolFrom(core.WithBindParamStringFunc("param", getDynamicValue))
-```
-
-{{< notice info >}} You don't need to modify tool configurations to bind parameter values. {{< /notice >}}

-custom logic) managed by the Toolbox into your workflows, especially those
-involving Large Language Models (LLMs).
-
-## Installation
-
-```bash
-go get github.com/googleapis/mcp-toolbox-sdk-go
-```
-This SDK is supported on Go version 1.24.4 and higher.
-
-{{< notice note >}}
-While the SDK itself is synchronous, you can execute its functions within goroutines to achieve asynchronous behavior.
-{{< /notice >}}
-
-
-## Quickstart
-
-Here's a minimal example to get you started. Ensure your Toolbox service is
-running and accessible.
-
-```go
-package main
-
-import (
-  "context"
-  "fmt"
-  "github.com/googleapis/mcp-toolbox-sdk-go/tbadk"
-)
-
-func quickstart() string {
-  inputs := map[string]any{"location": "London"}
-  client, err := tbadk.NewToolboxClient("http://localhost:5000")
-  if err != nil {
-    return fmt.Sprintln("Could not start Toolbox Client", err)
-  }
-  tool, err := client.LoadTool("get_weather", ctx)
-  if err != nil {
-    return fmt.Sprintln("Could not load Toolbox Tool", err)
-  }
-  // pass the tool.Context as ctx into the Run() method
-  result, err := tool.Run(ctx, inputs)
-  if err != nil {
-    return fmt.Sprintln("Could not invoke tool", err)
-  }
-  return fmt.Sprintln(result["output"])
-}
-
-func main() {
-  fmt.Println(quickstart())
-}
-```
-
-## Usage
-
-Import and initialize a Toolbox client, pointing it to the URL of your running
-Toolbox service.
-
-```go
-import "github.com/googleapis/mcp-toolbox-sdk-go/tbadk"
-
-client, err := tbadk.NewToolboxClient("http://localhost:5000")
-```
-
-All interactions for loading and invoking tools happen through this client.
-
-{{< notice note >}}
-For advanced use cases, you can provide an external custom `http.Client`
-during initialization (e.g., `tbadk.NewToolboxClient(URL, core.WithHTTPClient(myClient)`). If you provide your own session, you are responsible for managing its lifecycle;
-`ToolboxClient` *will not* close it.
-{{< /notice >}}
-
-## Transport Protocols
-
-The SDK supports multiple transport protocols. By default, the client uses the latest supported version of the **Model Context Protocol (MCP)**.
-
-You can explicitly select a protocol using the `core.WithProtocol` option during client initialization.
-
-{{< notice note >}}* **Native Toolbox Transport**: This uses the service's native **REST over HTTP** API.
-* **MCP Transports**: These options use the **Model Context Protocol over HTTP**.
-{{< /notice >}}
-
-### Supported Protocols
-
-| Constant | Description |
-| :--- | :--- |
-| `core.MCP` | **(Default)** Alias for the latest supported MCP version (currently `v2025-06-18`). |
-| `core.Toolbox` | The native Toolbox HTTP protocol. |
-| `core.MCPv20251125` | MCP Protocol version 2025-11-25. |
-| `core.MCPv20250618` | MCP Protocol version 2025-06-18. |
-| `core.MCPv20250326` | MCP Protocol version 2025-03-26. |
-| `core.MCPv20241105` | MCP Protocol version 2024-11-05. |
-
-### Example
-
-```go
-import (
-    "github.com/googleapis/mcp-toolbox-sdk-go/core"
-    "github.com/googleapis/mcp-toolbox-sdk-go/tbadk"
-)
-
-// Initialize with the native Toolbox protocol
-client, err := tbadk.NewToolboxClient(
-    "http://localhost:5000",
-    core.WithProtocol(core.Toolbox),
-)
-
-// Initialize with the MCP Protocol 2025-03-26
-client, err := tbadk.NewToolboxClient(
-    "http://localhost:5000",
-    core.WithProtocol(core.MCPv20250326),
-)
-
-```
-
-## Loading Tools
-
-You can load tools individually or in groups (toolsets) as defined in your
-Toolbox service configuration. Loading a toolset is convenient when working with
-multiple related functions, while loading a single tool offers more granular
-control.
-
-### Load a toolset
-
-A toolset is a collection of related tools. You can load all tools in a toolset
-or a specific one:
-
-```go
-// Load default toolset by providing an empty string as the name
-tools, err := client.LoadToolset("", ctx)
-
-// Load a specific toolset
-tools, err := client.LoadToolset("my-toolset", ctx)
-```
-
-`LoadToolset` returns a slice of the ToolboxTool structs (`[]ToolboxTool`).
-
-
-### Load a single tool
-
-Loads a specific tool by its unique name. This provides fine-grained control.
-
-```go
-tool, err = client.LoadTool("my-tool", ctx)
-```
-
-## Invoking Tools
-
-Once loaded, tools behave like Go structs. You invoke them using `Run` method
-by passing arguments corresponding to the parameters defined in the tool's
-configuration within the Toolbox service.
-
-```go
-tool, err = client.LoadTool("my-tool", ctx)
-inputs := map[string]any{"location": "London"}
-// Pass the tool.Context as ctx to the Run() function
-result, err := tool.Run(ctx, inputs)
-```
-
-{{< notice tip >}}For a more comprehensive guide on setting up the Toolbox service itself, which
-you'll need running to use this SDK, please refer to the [Toolbox Quickstart
-Guide](https://googleapis.github.io/genai-toolbox/getting-started/local_quickstart).
-{{< /notice >}}
-
-## Client to Server Authentication
-
-This section describes how to authenticate the ToolboxClient itself when
-connecting to a Toolbox server instance that requires authentication. This is
-crucial for securing your Toolbox server endpoint, especially when deployed on
-platforms like Cloud Run, GKE,  or any environment where unauthenticated access is restricted.
-
-This client-to-server authentication ensures that the Toolbox server can verify
-the identity of the client making the request before any tool is loaded or
-called. It is different from [Authenticating Tools](#authenticating-tools),
-which deals with providing credentials for specific tools within an already
-connected Toolbox session.
-
-### When is Client-to-Server Authentication Needed?
-
-You'll need this type of authentication if your Toolbox server is configured to
-deny unauthenticated requests. For example:
-
-- Your Toolbox server is deployed on Cloud Run and configured to "Require authentication."
-- Your server is behind an Identity-Aware Proxy (IAP) or a similar
-  authentication layer.
-- You have custom authentication middleware on your self-hosted Toolbox server.
-
-Without proper client authentication in these scenarios, attempts to connect or
-make calls (like `LoadTool`) will likely fail with `Unauthorized` errors.
-
-### How it works
-
-The `ToolboxClient` allows you to specify TokenSources that dynamically generate HTTP headers for
-every request sent to the Toolbox server. The most common use case is to add an
-Authorization header with a bearer token (e.g., a Google ID token).
-
-These header-generating functions are called just before each request, ensuring
-that fresh credentials or header values can be used.
-
-### Configuration
-
-You can configure these dynamic headers as seen below:
-
-
-```go
-import (
-  "github.com/googleapis/mcp-toolbox-sdk-go/core"
-  "github.com/googleapis/mcp-toolbox-sdk-go/tbadk"
-)
-
-tokenProvider := func() string {
-  return "header3_value"
-}
-
-staticTokenSource := oauth2.StaticTokenSource(&oauth2.Token{AccessToken: "header2_value"})
-dynamicTokenSource := core.NewCustomTokenSource(tokenProvider)
-
-client, err := tbadk.NewToolboxClient(
-  "toolbox-url",
-  core.WithClientHeaderString("header1", "header1_value"),
-  core.WithClientHeaderTokenSource("header2", staticTokenSource),
-  core.WithClientHeaderTokenSource("header3", dynamicTokenSource),
-)
-```
-
-### Authenticating with Google Cloud Servers
-
-For Toolbox servers hosted on Google Cloud (e.g., Cloud Run) and requiring
-`Google ID token` authentication, the helper module
-[auth_methods](/core/auth.go) provides utility functions.
-
-### Step by Step Guide for Cloud Run
-
-1. **Configure Permissions**: [Grant](https://cloud.google.com/run/docs/securing/managing-access#service-add-principals) the `roles/run.Runr` IAM role on the Cloud
-   Run service to the principal. This could be your `user account email` or a
-   `service account`.
-2. **Configure Credentials**
-    - Local Development: Set up
-   [ADC](https://cloud.google.com/docs/authentication/set-up-adc-local-dev-environment).
-    - Google Cloud Environments: When running within Google Cloud (e.g., Compute
-      Engine, GKE, another Cloud Run service, Cloud Functions), ADC is typically
-      configured automatically, using the environment's default service account.
-3. **Connect to the Toolbox Server**
-    ```go
-    import (
-      "github.com/googleapis/mcp-toolbox-sdk-go/core"
-      "github.com/googleapis/mcp-toolbox-sdk-go/tbadk"
-      "context"
-    )
-
-    ctx := context.Background()
-
-    token, err := core.GetGoogleIDToken(ctx, URL)
-
-    client, err := tbadk.NewToolboxClient(
-      URL,
-      core.WithClientHeaderString("Authorization", token),
-    )
-
-    // Now, you can use the client as usual.
-    ```
-
-## Authenticating Tools
-
-{{< notice warning >}} **Always use HTTPS** to connect your application with the Toolbox service,
-especially in **production environments** or whenever the communication
-involves **sensitive data** (including scenarios where tools require
-authentication tokens). Using plain HTTP lacks encryption and exposes your
-application and data to significant security risks, such as eavesdropping and tampering.
-{{< /notice >}}
-
-Tools can be configured within the Toolbox service to require authentication,
-ensuring only authorized users or applications can invoke them, especially when
-accessing sensitive data.
-
-### When is Authentication Needed?
-
-Authentication is configured per-tool within the Toolbox service itself. If a
-tool you intend to use is marked as requiring authentication in the service, you
-must configure the SDK client to provide the necessary credentials (currently
-Oauth2 tokens) when invoking that specific tool.
-
-### Supported Authentication Mechanisms
-
-The Toolbox service enables secure tool usage through **Authenticated Parameters**.
-For detailed information on how these mechanisms work within the Toolbox service and how to configure them, please refer to [Toolbox Service Documentation - Authenticated Parameters](https://googleapis.github.io/genai-toolbox/resources/tools/#authenticated-parameters).
-
-### Step 1: Configure Tools in Toolbox Service
-
-First, ensure the target tool(s) are configured correctly in the Toolbox service
-to require authentication. Refer to the [Toolbox Service Documentation -
-Authenticated
-Parameters](https://googleapis.github.io/genai-toolbox/resources/tools/#authenticated-parameters)
-for instructions.
-
-### Step 2: Configure SDK Client
-
-Your application needs a way to obtain the required Oauth2 token for the
-authenticated user. The SDK requires you to provide a function capable of
-retrieving this token *when the tool is invoked*.
-
-#### Provide an ID Token Retriever Function
-
-You must provide the SDK with a function that returns the
-necessary token when called. The implementation depends on your application's
-authentication flow (e.g., retrieving a stored token, initiating an OAuth flow).
-
-{{< notice info >}}
-The name used when registering the getter function with the SDK (e.g.,
-`"my_api_token"`) must exactly match the `name` of the corresponding
-`authServices` defined in the tool's configuration within the Toolbox service.
-{{< /notice >}}
-
-```go
-func getAuthToken() string {
-  // ... Logic to retrieve ID token (e.g., from local storage, OAuth flow)
-  // This example just returns a placeholder. Replace with your actual token retrieval.
-  return "YOUR_ID_TOKEN" // Placeholder
-}
-```
-
-{{< notice tip >}} Your token retriever function is invoked every time an authenticated parameter
-requires a token for a tool call. Consider implementing caching logic within
-this function to avoid redundant token fetching or generation, especially for
-tokens with longer validity periods or if the retrieval process is resource-intensive.
-{{< /notice >}}
-
-#### Option A: Add Default Authentication to a Client
-
-You can add default tool level authentication to a client.
-Every tool / toolset loaded by the client will contain the auth token.
-
-```go
-
-ctx := context.Background()
-
-client, err := tbadk.NewToolboxClient("http://127.0.0.1:5000",
-  core.WithDefaultToolOptions(
-    core.WithAuthTokenString("my-auth-1", "auth-value"),
-  ),
-)
-
-AuthTool, err := client.LoadTool("my-tool", ctx)
-```
-
-#### Option B: Add Authentication to a Loaded Tool
-
-You can add the token retriever function to a tool object *after* it has been
-loaded. This modifies the specific tool instance.
-
-```go
-
-ctx := context.Background()
-
-client, err := tbadk.NewToolboxClient("http://127.0.0.1:5000")
-
-tool, err := client.LoadTool("my-tool", ctx)
-
-AuthTool, err := tool.ToolFrom(
-  core.WithAuthTokenSource("my-auth", headerTokenSource),
-  core.WithAuthTokenString("my-auth-1", "value"),
-  )
-```
-
-#### Option C: Add Authentication While Loading Tools
-
-You can provide the token retriever(s) directly during the `LoadTool` or
-`LoadToolset` calls. This applies the authentication configuration only to the
-tools loaded in that specific call, without modifying the original tool objects
-if they were loaded previously.
-
-```go
-AuthTool, err := client.LoadTool("my-tool", ctx, core.WithAuthTokenString("my-auth-1", "value"))
-
-// or
-
-AuthTools, err := client.LoadToolset(
-  "my-toolset",
-  ctx,
-  core.WithAuthTokenString("my-auth-1", "value"),
-)
-```
-
-{{< notice note >}}
-Adding auth tokens during loading only affect the tools loaded within that call.
-{{< /notice >}}
-
-### Complete Authentication Example
-
-```go
-import "github.com/googleapis/mcp-toolbox-sdk-go/core"
-import "fmt"
-
-func getAuthToken() string {
-  // ... Logic to retrieve ID token (e.g., from local storage, OAuth flow)
-  // This example just returns a placeholder. Replace with your actual token retrieval.
-  return "YOUR_ID_TOKEN" // Placeholder
-}
-
-func main() {
-  ctx := context.Background()
-  inputs := map[string]any{"input": "some input"}
-
-  dynamicTokenSource := core.NewCustomTokenSource(getAuthToken)
-
-  client, err := tbadk.NewToolboxClient("http://127.0.0.1:5000")
-  tool, err := client.LoadTool("my-tool", ctx)
-  AuthTool, err := tool.ToolFrom(core.WithAuthTokenSource("my_auth", dynamicTokenSource))
-
-  result, err := AuthTool.Run(ctx, inputs)
-
-  fmt.Println(result)
-}
-```
-
-{{< notice note >}}An auth token getter for a specific name (e.g., "GOOGLE_ID") will replace any client header with the same name followed by "_token" (e.g.,"GOOGLE_ID_token").
-{{< /notice >}}
-
-## Binding Parameter Values
-
-The SDK allows you to pre-set, or "bind", values for specific tool parameters
-before the tool is invoked or even passed to an LLM. These bound values are
-fixed and will not be requested or modified by the LLM during tool use.
-
-### Why Bind Parameters?
-
-- **Protecting sensitive information:**  API keys, secrets, etc.
-- **Enforcing consistency:** Ensuring specific values for certain parameters.
-- **Pre-filling known data:**  Providing defaults or context.
-
-{{< notice info >}}
-The parameter names used for binding (e.g., `"api_key"`) must exactly match the
-parameter names defined in the tool's configuration within the Toolbox service.
-{{< /notice >}}
-
-{{< notice note >}}
-You do not need to modify the tool's configuration in the Toolbox service to bind parameter values using the SDK.
-{{< /notice >}}
-
-#### Option A: Add Default Bound Parameters to a Client
-
-You can add default tool level bound parameters to a client. Every tool / toolset
-loaded by the client will have the bound parameter.
-
-```go
-
-ctx := context.Background()
-
-client, err := tbadk.NewToolboxClient("http://127.0.0.1:5000",
-  core.WithDefaultToolOptions(
-    core.WithBindParamString("param1", "value"),
-  ),
-)
-
-boundTool, err := client.LoadTool("my-tool", ctx)
-```
-
-### Option B: Binding Parameters to a Loaded Tool
-
-Bind values to a tool object *after* it has been loaded. This modifies the
-specific tool instance.
-
-```go
-client, err := tbadk.NewToolboxClient("http://127.0.0.1:5000")
-
-tool, err := client.LoadTool("my-tool", ctx)
-
-boundTool, err := tool.ToolFrom(
-  core.WithBindParamString("param1", "value"),
-  core.WithBindParamString("param2", "value")
-  )
-```
-
-### Option C: Binding Parameters While Loading Tools
-
-Specify bound parameters directly when loading tools. This applies the binding
-only to the tools loaded in that specific call.
-
-```go
-boundTool, err := client.LoadTool("my-tool", ctx, core.WithBindParamString("param", "value"))
-
-// OR
-
-boundTool, err := client.LoadToolset("", ctx, core.WithBindParamString("param", "value"))
-```
-
-{{< notice note >}} 
-Bound values during loading only affect the tools loaded in that call.
-{{< /notice >}}
-
-### Binding Dynamic Values
-
-Instead of a static value, you can bind a parameter to a synchronous or
-asynchronous function. This function will be called *each time* the tool is
-invoked to dynamically determine the parameter's value at runtime.
-Functions with the return type (data_type, error) can be provided.
-
-```go
-getDynamicValue := func() (string, error) { return "req-123", nil }
-
-dynamicBoundTool, err := tool.ToolFrom(core.WithBindParamStringFunc("param", getDynamicValue))
-```
-
-{{< notice info >}} 
-You don't need to modify tool configurations to bind parameter values.
-{{< /notice >}}
-
-## Using with ADK Go
-
-After altering the tool to your needs, type-assert the ToolboxTool and pass it to the LLM agent.
-
-### For a single tool
-
-```go
-
-toolboxtool, err = client.LoadTool("my-tool", ctx)
-
-// <Bind parameters & add authentication here>
-
-llmagent, err := llmagent.New(llmagent.Config{
-  Name:        "assistant",
-  Model:       model,
-  Description: "Agent to answer questions.",
-  Tools:       []tool.Tool{&toolboxtool},
-})
-```
-
-### For a toolset
-
-```go
-toolboxtools, err := client.LoadToolset("", ctx)
-
-// <Bind parameters & add authentication here>
-
-toolsList := make([]tool.Tool, len(toolboxtools))
-	for i := range toolboxtools {
-		toolsList[i] = &toolboxtools[i]
-	}
-
-llmagent, err := llmagent.New(llmagent.Config{
-  Name:        "assistant",
-  Model:       model,
-  Description: "Agent to answer questions.",
-  Tools:       toolsList,
-})
-
-```
-
-The reason we have to type assert it before passing it to ADK Go, is because it requires a generic `tool.Tool` interface. You can always convert it back to `ToolboxTool` format to access the specialized  methods.

-  Python SDKs to connect to the MCP Toolbox server.
----
-
-
-## Overview
-
-The MCP Toolbox service provides a centralized way to manage and expose tools
-(like API connectors, database query tools, etc.) for use by GenAI applications.
-
-These Python SDKs act as clients for that service. They handle the communication needed to:
-
-* Fetch tool definitions from your running Toolbox instance.
-* Provide convenient Python objects or functions representing those tools.
-* Invoke the tools (calling the underlying APIs/services configured in Toolbox).
-* Handle authentication and parameter binding as needed.
-
-By using these SDKs, you can easily leverage your Toolbox-managed tools directly
-within your Python applications or AI orchestration frameworks.
