Authorize

Complete Darwin OAuth and verify the seven current tools.
Replit documents self-serve custom servers and install links, but no public third-party catalog submission form. Keep any SDK fallback credential in Replit Secrets and persist Action IDs outside chat. Open the Darwin client guide or Replit’s MCP guide.
