  note: BeZero publishes a first-party MCP server on npm — but it wraps Metabase, their internal BI stack,
    not the BeZero Ratings API. There is no MCP surface over BeZero rating data. The tools[] below are
    a CANDIDATE derivation from the four operations in the published OpenAPI, not something BeZero ships.

notes:
- Every operation in the BeZero Ratings API is a GET; a candidate MCP server would be entirely read-only.
- Rate limit is 1000 requests per minute API-wide, so an MCP server fronting this API should surface Retry-After
  from the 429 response rather than retrying blind.
