Cursor config and which tool to call.

Markdown Full spec OpenAPI

Endpoint: https://mcp.fulldatasets.com/mcp

Transport: streamable HTTP (JSON-RPC). Same Bearer key as REST.

Read the tool list in MCP tools. Full agent spec: https://fulldatasets.com/docs.md

Cursor

{
  "mcpServers": {
    "fulldatasets": {
      "url": "https://mcp.fulldatasets.com/mcp",
      "headers": {
        "Authorization": "Bearer fds_live_<kid>_<secret>"
      }
    }
  }
}

The header value is Bearer plus one space plus the key. Do not nest a second Bearer.

After connect, initialize returns instructions that point at this docs set. tools/list is the live tool catalog.

Check

lookup_isbn 9780593135204 should return Project Hail Mary, Andy Weir, and a description.

Auth failures

401 on POST /mcp means the header is wrong or the key is revoked. Tool names are not the problem.

Rate limits are enforced on the API behind the service binding (120 / 60s per key), same as REST.
