Troubleshooting

No results returned -- state is required for search_facilities, so make sure it is set; then broaden by removing the city/treatment_type/insurance filters or trying a different state. Call list_states to see where coverage exists.
HTTP 429 (rate limited) -- the free tier allows 100 calls per IP per day, resetting at 00:00 UTC. For higher volume, see API Access above.
Can't connect -- point your client at the remote endpoint, no API key required:
Terminal
```
npx -y mcp-remote https://gth-mcp-server.pages.dev/mcp
```
403 from a browser -- the /mcp endpoint validates the Origin header to prevent DNS rebinding. Standard MCP clients (Claude Desktop, mcp-remote, server-to-server) send no Origin header and connect fine; only disallowed browser origins are blocked.
