概要

What is click-mcp?

click-mcp is a Python library that extends Click applications with Model Context Protocol (MCP) support, allowing AI agents to discover and interact with CLI tools programmatically. It provides a simple decorator that converts Click commands into MCP tools.

How to use click-mcp?

Install via pip (pip install click-mcp), then decorate your Click group with @click_mcp(). Run the MCP server using python my_app.py mcp (or a custom command name if configured). The decorator automatically converts Click commands into MCP tools with named parameters and dot‑notation for nested groups.

Key features of click-mcp

  • Simple @click_mcp decorator syntax
  • Automatic conversion of Click commands to MCP tools
  • Support for nested command groups
  • Support for positional arguments
  • Stdio‑based MCP server for easy integration

Use cases of click-mcp

  • Turn any existing Click CLI into an MCP‑compatible tool
  • Allow AI agents to invoke CLI commands with structured parameters
  • Expose complex nested command hierarchies as discoverable MCP tools

FAQ from click-mcp

What is the Model Context Protocol (MCP)?

MCP is an open standard for AI agents to interact with tools and applications in a structured way.

What are the dependencies or runtime requirements?

click-mcp requires Python and the Click library. The README assumes a standard Python environment.

How can I customize the MCP command name?

Use the command_name parameter in the @click_mcp decorator, e.g. @click_mcp(command_name="start-mcp").

How are command errors handled?

When a Click command raises an exception, click-mcp captures the error and returns it as part of the MCP response, enabling AI agents to handle errors gracefully.

How are nested commands named when exposed as MCP tools?

Nested commands use dot notation (e.g., users.create).
