Summary
Gives Claude direct shell access through two tools: execute for running bash commands with optional timeouts and background mode, and get_job_status for checking on long-running jobs. Reach for this when you need Claude to handle build scripts, file operations like find and grep, or system inspection commands. The background job support means you can start a dev server or watch process, then query its status later without blocking. Ships with both stdio and HTTP transports, so you can run it locally via npx or host it as a service. The usual warnings apply: this executes arbitrary commands on your system, so think carefully about where you deploy it.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.
