Click Clack MCP Server

MCPOpen SourceApache-2.023.3

by JasonSteving99 • Tools & CLI

Automatically discovers Python click/asyncclick commands and exposes them as an MCP server and simple web UI so agents and Claude Desktop can run your local scripts as tools.

Example Use Cases

1
Invoke local Python click/asyncclick commands as callable tools without writing custom wrappers.
2
Register and use command-line utilities inside Claude Desktop (or other MCP clients) via an auto-generated MCP server.
3
A quick, auto-generated web UI to prompt for command arguments and test CLI scripts interactively.

Description

Click Clack crawls a project for @click.command-decorated functions, imports them, and auto-generates a minimalist web UI and an MCP server wrapper. It uses Marimo for the UI and FastMCP for MCP server functionality, and can be run via uv to register tools with clients like Claude Desktop. When used as an MCP tool it captures stdout/stderr from commands and returns that output as the tool response. It supports many common click parameter types (str, int, float, bool, Choice, Path, File, DateTime, ranges, etc.).
