Every MCP server you have configured injects its tool definitions into your context window on every single message — whether you use it that session or not. Vibedock sits in your macOS menu bar and lets you toggle MCPs on and off in one click. It automatically kills and relaunches your Claude sessions so the change actually takes effect.
Looking beyond Vibedock? Try Masko Code for watchdog-style monitoring of Claude Code, or Chive, a slick macOS companion. Need live metrics? AgentNotch pipes telemetry into the notch, while Conductor runs multiple Claude Codes in parallel.
