+description: >
+  Connect your IDE to Oracle using Toolbox.
+---
+
+[Model Context Protocol (MCP)](https://modelcontextprotocol.io/introduction) is
+an open protocol for connecting Large Language Models (LLMs) to data sources
+like Oracle. This guide covers how to use [MCP Toolbox for Databases][toolbox]
+to expose your developer assistant tools to an Oracle instance:
+
+* [Cursor][cursor]
+* [Windsurf][windsurf] (Codium)
+* [Visual Studio Code][vscode] (Copilot)
+* [Cline][cline]  (VS Code extension)
+* [Claude desktop][claudedesktop]
+* [Claude code][claudecode]
+* [Gemini CLI][geminicli]
+* [Gemini Code Assist][geminicodeassist]
+
+[toolbox]: https://github.com/googleapis/genai-toolbox

+
+## Set up the database
+
+1. Create or select an Oracle instance.
+
+1. Create or reuse a database user and have the username and password ready.
+
+## Install MCP Toolbox
+
+1. Download the latest version of Toolbox as a binary. Select the [correct

+description: >
+  How to generate agent skills from a toolset.
+---
+
+The `skills-generate` command allows you to convert a **toolset** into an **Agent Skill**. A toolset is a collection of tools, and the generated skill will contain metadata and execution scripts for all tools within that toolset, complying with the [Agent Skill specification](https://agentskills.io/specification).
+
+## Before you begin
+
+1. Make sure you have the `toolbox` executable in your PATH.
+2. Make sure you have [Node.js](https://nodejs.org/) installed on your system.
+
+## Generating a Skill from a Toolset
+
+A skill package consists of a `SKILL.md` file (with required YAML frontmatter) and a set of Node.js scripts. Each tool defined in your toolset maps to a corresponding script in the generated Node.js scripts (`.js`) that work across different platforms (Linux, macOS, Windows).
+
+
+### Command Usage
+
+The basic syntax for the command is:
+
+```bash
+toolbox <tool-source> skills-generate \
+  --name <skill-name> \
+  --toolset <toolset-name> \
+  --description <description> \
+  --output-dir <output-directory>
+```
+
+- `<tool-source>`: Can be `--tools-file`, `--tools-files`, `--tools-folder`, and `--prebuilt`. See the [CLI Reference](../reference/cli.md) for details.
+- `--name`: Name of the generated skill.
+- `--description`: Description of the generated skill.
+- `--toolset`: (Optional) Name of the toolset to convert into a skill. If not provided, all tools will be included.
+- `--output-dir`: (Optional) Directory to output generated skills (default: "skills").
+
+{{< notice note >}}
+**Note:** The `<skill-name>` must follow the Agent Skill [naming convention](https://agentskills.io/specification): it must contain only lowercase alphanumeric characters and hyphens, cannot start or end with a hyphen, and cannot contain consecutive hyphens (e.g., `my-skill`, `data-processing`).
+{{< /notice >}}
+
+### Example: Custom Tools File
+
+1. Create a `tools.yaml` file with a toolset and some tools:
+
+   ```yaml
+   tools:
+     tool_a:
+       description: "First tool"
+       run:
+         command: "echo 'Tool A'"
+     tool_b:
+       description: "Second tool"
+       run:
+         command: "echo 'Tool B'"
+   toolsets:
+     my_toolset:
+       tools:
+         - tool_a
+         - tool_b
+   ```
+
+2. Generate the skill:
+
+   ```bash
+   toolbox --tools-file tools.yaml skills-generate \
+     --name "my-skill" \
+     --toolset "my_toolset" \
+     --description "A skill containing multiple tools" \
+     --output-dir "generated-skills"
+   ```
+
+3. The generated skill directory structure:
+
+   ```text
+   generated-skills/
+   └── my-skill/
+       ├── SKILL.md
+       ├── assets/
+       │   ├── tool_a.yaml
+       │   └── tool_b.yaml
+       └── scripts/
+           ├── tool_a.js
+           └── tool_b.js
+   ```
+
+   In this example, the skill contains two Node.js scripts (`tool_a.js` and `tool_b.js`), each mapping to a tool in the original toolset.
+
+### Example: Prebuilt Configuration
+
+You can also generate skills from prebuilt toolsets:
+
+```bash
+toolbox --prebuilt alloydb-postgres-admin skills-generate \
+  --name "alloydb-postgres-admin" \
+  --description "skill for performing administrative operations on alloydb"
+```
+
+## Installing the Generated Skill in Gemini CLI
+
+Once you have generated a skill, you can install it into the Gemini CLI using the `gemini skills install` command.
+
+### Installation Command
+
+Provide the path to the directory containing the generated skill:
+
+```bash
+gemini skills install /path/to/generated-skills/my-skill
+```
+
+Alternatively, use ~/.gemini/skills as the `--output-dir` to generate the skill straight to the Gemini CLI.

+## 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)

+
+### MCP Security Parameters
+
+CockroachDB integration includes security features following the [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) specification:
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `readOnlyMode` | boolean | true | Enables read-only mode by default (MCP requirement) |
+| `enableWriteMode` | boolean | false | Explicitly enable write operations (INSERT/UPDATE/DELETE/CREATE/DROP) |

+| `sslmode` | `disable`, `require`, `verify-ca`, `verify-full` | SSL/TLS mode (CockroachDB Cloud requires `require` or higher) |
+| `sslrootcert` | file path | Path to root certificate for SSL verification |
+| `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
+
+tools:
+  execute_sql:
+    type: cockroachdb-execute-sql
+    source: my_cockroachdb
+    description: Execute any SQL statement against the CockroachDB database
+```
+
+## Usage Examples
+
+### Simple SELECT Query
+
+```json
+{
+  "sql": "SELECT * FROM users LIMIT 10"
+}
+```
+
+### Query with Aggregations
+
+```json
+{
+  "sql": "SELECT category, COUNT(*) as count, SUM(amount) as total FROM expenses GROUP BY category ORDER BY total DESC"
+}
+```
+
+### Database Introspection
+
+```json
+{
+  "sql": "SHOW TABLES"
+}
+```
+
+```json
+{
+  "sql": "SHOW COLUMNS FROM expenses"
+}
+```
+
+### Multi-Region Information
+
+```json
+{
+  "sql": "SHOW REGIONS FROM DATABASE defaultdb"
+}
+```
+
+```json
+{
+  "sql": "SHOW ZONE CONFIGURATIONS"
+}
+```
+
+## CockroachDB-Specific Features
+
+### Check Cluster Version
+
+```json
+{
+  "sql": "SELECT version()"
+}
+```
+
+### View Node Status
+
+```json
+{
+  "sql": "SELECT node_id, address, locality, is_live FROM crdb_internal.gossip_nodes"
+}
+```
+
+### Check Replication Status
+
+```json
+{
+  "sql": "SELECT range_id, start_key, end_key, replicas, lease_holder FROM crdb_internal.ranges LIMIT 10"
+}
+```
+
+### View Table Regions
+
+```json
+{
+  "sql": "SHOW REGIONS FROM TABLE expenses"
+}
+```
+
+## Configuration
+
+### Required Fields
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `type` | string | Must be `cockroachdb-execute-sql` |
+| `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 |
+
+## Parameters
+
+The tool accepts a single runtime parameter:
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `sql` | string | The SQL statement to execute |
+
+## Best Practices
+
+### Use for Exploration, Not Production
+
+This tool is ideal for:
+- Interactive database exploration
+- Ad-hoc analysis and reporting
+- Debugging and troubleshooting
+- Schema inspection
+
+For production use cases, use [cockroachdb-sql](./cockroachdb-sql.md) with parameterized queries.
+
+### Be Cautious with Data Modification
+
+While this tool can execute any SQL statement, be careful with:
+- `INSERT`, `UPDATE`, `DELETE` statements
+- `DROP` or `ALTER` statements
+- Schema changes in production
+
+### Use LIMIT for Large Results
+
+Always use `LIMIT` clauses when exploring data:
+
+```sql
+SELECT * FROM large_table LIMIT 100
+```
+
+### Leverage CockroachDB's SQL Extensions
+
+CockroachDB supports PostgreSQL syntax plus extensions:
+
+```sql
+-- Show database survival goal
+SHOW SURVIVAL GOAL FROM DATABASE defaultdb;
+
+-- View zone configurations
+SHOW ZONE CONFIGURATION FOR TABLE expenses;
+
+-- Check table localities
+SHOW CREATE TABLE expenses;
+```
+
+## Error Handling
+
+The tool will return descriptive errors for:
+- **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
+tools:
+  get_user_with_orders:
+    type: cockroachdb-sql
+    source: my_cockroachdb
+    description: Get user details with their recent orders
+    statement: |
+      SELECT u.name, u.email, o.id as order_id, o.order_date, o.total_amount
+      FROM users u
+      LEFT JOIN orders o ON u.id = o.user_id
+      WHERE u.id = $1
+      ORDER BY o.order_date DESC
+      LIMIT 10
+    parameters:
+      - name: user_id
+        type: string
+        description: The user's UUID
+```
+
+### Handle NULL Values
+
+Use COALESCE or NULL checks when dealing with nullable columns:
+
+```sql
+SELECT id, description, COALESCE(notes, 'No notes') as notes
+FROM expenses
+WHERE user_id = $1
+```
+
+## Error Handling
+
+The tool automatically handles:
+- **Connection errors**: Retried with exponential backoff
+- **Serialization conflicts**: Automatically retried using cockroach-go library
+- **Invalid parameters**: Returns descriptive error messages
+- **SQL syntax errors**: Returns database error details
+
+## Advanced Usage
+
+### Aggregations
+
+```yaml
+tools:
+  expense_summary:
+    type: cockroachdb-sql
+    source: my_cockroachdb
+    description: Get expense summary by category for a user
+    statement: |
+      SELECT 
+        category,
+        COUNT(*) as count,
+        SUM(amount) as total_amount,
+        AVG(amount) as avg_amount
+      FROM expenses
+      WHERE user_id = $1
+        AND expense_date >= $2
+      GROUP BY category
+      ORDER BY total_amount DESC
+    parameters:

+### Other Levels

 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.

-  How to add pre and post processing to your JS toolbox applications.
---
-
-## Prerequisites
-
-This tutorial assumes that you have set up a basic toolbox application as described in the [local quickstart](../../getting-started/local_quickstart_js).
-
-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.
-
-```js
-{{< include "js/adk/agent.js" >}}
-```
-
-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 %}}
-{{% 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" >}}
-```
-
-For more information, see the [LangChain Middleware documentation](https://js.langchain.com/docs/introduction/middleware).
-You can also add model-level (`wrap_model`) and agent-level (`before_agent`, `after_agent`) hooks to intercept messages at different stages of the execution loop. See the [LangChain Middleware documentation](https://js.langchain.com/docs/introduction/middleware) for details on these additional hook types.

 ```py
 {{< include "python/langchain/agent.py" >}}
 ```

-For more information, see the [LangChain Middleware documentation](https://docs.langchain.com/oss/python/langchain/middleware/custom#wrap-style-hooks).
 You can also add model-level (`wrap_model`) and agent-level (`before_agent`, `after_agent`) hooks to intercept messages at different stages of the execution loop. See the [LangChain Middleware documentation](https://docs.langchain.com/oss/python/langchain/middleware/custom#wrap-style-hooks) for details on these additional hook types.

+## Results
+
+The output should look similar to the following. Note that exact responses may vary due to the non-deterministic nature of LLMs and differences between orchestration frameworks.
+
+```
+AI: Booking Confirmed! You earned 500 Loyalty Points with this stay.
+
+AI: Error: Maximum stay duration is 14 days.
