Reference

The complete reference — every tool, every saved prompt, every error code.

All 16 tools

Nine read tools, seven that change something. What each returns and its limits.

Saved prompts & widgets

Four ready-made questions and seven dashboard cards.

Error codes

Every refusal the connector can return, and what it means.

​

Endpoints

For completeness — you normally only ever paste the first one.

Endpoint	Purpose
POST /mcp	The connector. Requires Authorization: Bearer nl_mcp_…. The only data path.
GET /mcp	405 by design. The connector answers each request and offers no streaming channel; 405 tells a client to stop trying to open one.
GET /healthz	Liveness. With a token it also reports that token’s store, allowed tools and expiry — see Other AI clients.
