MCP Client node

1. Add an MCP Client node.
2. Endpoint: https://mcp.altlaboratories.com/mcp
3. Authentication: header Authorization = Bearer alt_live_...
4. The node discovers all tools; pick one (e.g. oos_check_interactions) and map inputs.

Plain HTTP Request node

Any endpoint from the API reference works directly:

• Method: GET
• URL: https://platform.altlaboratories.com/v1/oos/search?q={{ $json.query }}
• Header: Authorization: Bearer alt_live_...

Responses are JSON with cursor pagination (next_cursor) and, for health content, a disclaimer field your workflow should carry through to any user-facing output.
