Iterm-Mcp – AI Terminal/REPL Control for iTerm2

In plain words

Iterm-mcp is an MCP server that connects AI assistants like Claude Desktop to iTerm2 terminals, allowing direct interaction with command-line environments. Users can point their AI assistant at terminal output to get debugging help, run commands, start REPLs, and explore data. The tool integrates with Model Context Protocol compatible clients and optimizes token usage by letting the AI request only relevant output portions. It's designed for developers who want AI assistance directly within their terminal workflow.

From the sources

A Model Context Protocol server that executes commands in the current iTerm session - useful for REPL and CLI assistance - ferrislucas/iterm-mcp

A Model Context Protocol server that provides access to your iTerm session. Efficient Token Use: iterm-mcp gives the model the ability to inspect only the output that the model is interested in. The model typically only wants to see the last few lines of output even for long running commands. Natural Integration: You share iTerm with the model. You can ask questions about what's on the screen, or delegate a task to the model and watch as it performs each step. Full Terminal Control and REPL support: The model can start and interact with REPL's as well as send control characters like ctrl-c, ctrl-z, etc. Easy on the Dependencies: iterm-mcp is built with minimal dependencies and is runnable…from github.com

In the maker’s words, at launch

Hi HN! Ever wish you could just point your AI assistant at your terminal and say 'what's wrong with this output?' That's why I built iterm-mcp. It lets MCP clients like Claude Desktop directly interact with your iTerm2 terminal - reading logs, running commands, using REPLs, and helping debug issues. Want to explore…

  Tetris in a PDF▲1,289

  I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…

  I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!
