How clients sign in

OAuth sign-in. Client ID Metadata Documents: no. Dynamic Client Registration: yes. PKCE S256: yes.

  • authorization server metadata issuer "https://rapid-pole-17.authkit.app" differs from "https://rapid-pole-17.authkit.app/" only by a trailing slash; the spec requires an identical string, so strict clients reject it

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
