Get the setup for your client from your agent
This page is a daily snapshot. lurq's connect_check answers for the client you are wiring this server into, with the exact steps and the config to paste in that client's own format, and lurq mcp-pin tells you when the server changes. One command connects Claude Code, Cursor, VS Code and other agents:
npx lurqrun
Free to start. How connect_check works
From lurq's credential-free probe of this server's endpoint on Sep 17, 2026, and each client's own documentation. This page refreshes every 24 hours. How the probe works, and how maintainers opt out. Source repository.
