- Rate limits: Same as Public API.
- Restricted states: If your account has state‑based restrictions, MCP returns compliant results (fields may be null).
Troubleshooting
- ''I don't see the tools in Claude'': Confirm connector is added and you have permission to use tools. Restart the app.
- Credits: If a call returns partial or no results, charges follow API rules (no charge on failed lookups).
Security tips
- Store API keys in secure credentials (Claude/OS keychain, n8n credentials).
- Limit tool permissions in Claude Connectors to the minimum needed.
