description: 'Refuel serves a live, anonymous, remote MCP endpoint at https://docs.refuel.ai/mcp. It is
  a DOCUMENTATION server, not a Refuel Cloud API server: the three tools search and read the docs corpus
  and file docs feedback. None of them call the Refuel Cloud REST API at cloud-api.refuel.ai, so an agent
  can read Refuel''s documentation over MCP but cannot create a project, ingest a dataset, or label a
  row over MCP. See mcp/refuel-ai-tool-crosswalk.yml for the operation-level divergence.'

observations:
- The tool description advertises a virtual filesystem containing "documentation pages and OpenAPI specs",
  but `find / -name "*openapi*"` over that filesystem returns nothing and `ls -R /` lists only .mdx docs
  pages. The docs host publishes no OpenAPI; the real spec is served at https://cloud-api.refuel.ai/openapi.json,
  on the API host.
- Two of the three tool descriptions carry unedited Mintlify boilerplate examples (`/api-reference/create-customer.mdx`)
  that do not exist in Refuel's docs tree.
