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 18, 2026, and each client's own documentation. This page refreshes every 24 hours. How the probe works, and how maintainers opt out.
