What is codemcp?

codemcp is a Model Context Protocol (MCP) server that turns Claude into a pair programming assistant. It runs on your computer and is intended for Claude Pro subscribers ($20/month), working with Claude Desktop or the web version via a browser extension. Developers can ask Claude to implement features, fix bugs, and refactor codebases directly on their machine.

Run uvx --from git+https://github.com/ezyang/codemcp@prod codemcp serve to start the MCP server and configure the extension with the SSE URL (e.g., http://127.0.0.1:8000/sse). In Claude, create a project with instructions like Initialize codemcp with $PROJECT_DIR, and create a codemcp.toml file in your Git repository to define allowed commands (e.g., format, test).
