Model Context Protocol: scoped tools on your real processes.

AI editors connect to Rig’s local MCP hub and call tools (logs, status, restart) scoped to projects — not a raw shell on your machine.

Rig runs the hub locally; one-click link for Cursor, Claude, Codex, Copilot CLI, OpenCode, Pi, Windsurf, or VS Code. Any other MCP client can paste the hub JSON.
