-title: "Invoke Tools via CLI"
-type: docs
-weight: 10
-description: >
-  Learn how to invoke your tools directly from the command line using the `invoke` command.
----
-
-The `invoke` command allows you to invoke tools defined in your configuration directly from the CLI. This is useful for:
-
-- **Ephemeral Invocation:** Executing a tool without spinning up a full MCP server/client.
-- **Debugging:** Isolating tool execution logic and testing with various parameter combinations.
-
-{{< notice tip >}}
-**Keep configurations minimal:** The `invoke` command initializes *all* resources (sources, tools, etc.) defined in your configuration files during execution. To ensure fast response times, consider using a minimal configuration file containing only the tools you need for the specific invocation.
-{{< notice tip >}}
-
-## Prerequisites
-
-- You have the `toolbox` binary installed or built.
-- You have a valid tool configuration file (e.g., `tools.yaml`).
-
-## Basic Usage
-
-The basic syntax for the command is:
-
-```bash
-toolbox [--tools-file <path> | --prebuilt <name>] invoke <tool-name> [params]
-```
-
-- `<tool-name>`: The name of the tool you want to call. This must match the name defined in your `tools.yaml`.
-- `[params]`: (Optional) A JSON string representing the arguments for the tool.
-
-## Examples
-
-### 1. Calling a Tool without Parameters
-
-If your tool takes no parameters, simply provide the tool name:
-
-```bash
-toolbox  --tools-file tools.yaml invoke my-simple-tool
-```
-
-### 2. Calling a Tool with Parameters
-
-For tools that require arguments, pass them as a JSON string. Ensure you escape quotes correctly for your shell.
-
-**Example: A tool that takes parameters**
-
-Assuming a tool named `mytool` taking `a` and `b`:
-
-```bash
-toolbox --tools-file tools.yaml invoke mytool '{"a": 10, "b": 20}' 
-```
-
-**Example: A tool that queries a database**
-
-```bash
-toolbox  --tools-file tools.yaml invoke db-query '{"sql": "SELECT * FROM users LIMIT 5"}'
-```
-
-### 3. Using Prebuilt Configurations
-
-You can also use the `--prebuilt` flag to load prebuilt toolsets.
-
-```bash
-toolbox --prebuilt cloudsql-postgres invoke cloudsql-postgres-list-instances
-```
-
-## Troubleshooting
-
-- **Tool not found:** Ensure the `<tool-name>` matches exactly what is in your YAML file and that the file is correctly loaded via `--tools-file`.
-- **Invalid parameters:** Double-check your JSON syntax. The error message will usually indicate if the JSON parsing failed or if the parameters didn't match the tool's schema.
-- **Auth errors:** The `invoke` command currently does not support flows requiring client-side authorization (like OAuth flow initiation via the CLI). It works best for tools using service-side authentication (e.g., Application Default Credentials).

-title: "Pre and Post processing"
-type: docs
-weight: 1
-description: >
-  Pre and Post processing in GenAI applications.
----
-
-Pre and post processing allow developers to intercept and modify interactions between the agent and its tools or the user.
-
-> **Note**: These capabilities are typically features of **orchestration frameworks** (like LangChain, LangGraph, or Agent Builder) rather than the Toolbox SDK itself. However, Toolbox tools are designed to fully leverage these framework capabilities to support robust, secure, and compliant agent architectures.
-
-## Types of Processing
-
-### Pre-processing
-
-Pre-processing occurs before a tool is executed or an agent processes a message. Key types include:
-
-- **Input Sanitization & Redaction**: Detecting and masking sensitive information (like PII) in user queries or tool arguments to prevent it from being logged or sent to unauthorized systems.
-- **Business Logic Validation**: Verifying that the proposed action complies with business rules (e.g., ensuring a requested hotel stay does not exceed 14 days, or checking if a user has sufficient permission).
-- **Security Guardrails**: Analyzing inputs for potential prompt injection attacks or malicious payloads.
-
-### Post-processing
-
-Post-processing occurs after a tool has executed or the model has generated a response. Key types include:
-
-- **Response Enrichment**: Injecting additional data into the tool output that wasn't part of the raw API response (e.g., calculating loyalty points earned based on the booking value).
-- **Output Formatting**: Transforming raw data (like JSON or XML) into a more human-readable or model-friendly format to improve the agent's understanding.
-- **Compliance Auditing**: Logging the final outcome of transactions, including the original request and the result, to a secure audit trail.
-
-## Processing Scopes
-
-While processing logic can be applied at various levels (Agent, Model, Tool), this guide primarily focuses on **Tool Level** processing, which is most relevant for granular control over tool execution.
-
-### Tool Level (Primary Focus)
-
-Wraps individual tool executions. This is best for logic specific to a single tool or a set of tools.
-
-- **Scope**: Intercepts the raw inputs (arguments) to a tool and its outputs.
-- **Use Cases**: Argument validation, output formatting, specific privacy rules for sensitive tools.
-
-### Comparison with 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.

-This guide demonstrates how to implement these patterns in your Toolbox applications.

-The following example demonstrates how to use `ToolboxClient` with LangChain's middleware to implement pre and post processing for tool calls.
-
-```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.
