Overview

iterm-mcp is a Model Context Protocol server that provides access to your iTerm session. It allows a model to execute commands, inspect output, and interact with REPLs in the current iTerm session. The server is designed for efficient token use, natural integration with iTerm, and full terminal control. It's built with minimal dependencies and can be run via npx, making it easy to add to Claude Desktop and other MCP clients. However, the user is responsible for safe usage, as iterm-mcp does not evaluate the safety of commands.
