Iterm-mcp is a Model Context Protocol server that provides access to your iTerm session. It enables the model to observe terminal output efficiently by focusing on the portion of the stream it needs, typically the last few lines, enabling efficient token usage. The server supports natural integration by sharing the iTerm session with the model, allowing it to ask questions about what's on screen or delegate tasks and watch it execute steps. It provides full terminal control and REPL support, enabling the model to start and interact with REPLs and send control characters (e.g., ctrl-c, ctrl-z). It is designed with minimal dependencies and can run via npx, facilitating easy integration with Claude Desktop and other MCP clients. Tools exposed include write_to_terminal (writes commands to the active terminal and returns lines of output), read_terminal_output (reads a requested number of lines), and send_control_character (sends control characters). Requirements include iTerm2 running and Node 18+. The README also covers installation via Claude Desktop config or Smithery, and development/debugging approaches using the MCP Inspector.
