Pack: mozilla-observatory · Endpoint: https://gateway.pipeworx.io/mozilla-observatory/mcp

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/observatory_grade_distribution for the schema, then POST the same URL with its arguments for the data.

Grade distribution across every site the MDN HTTP Observatory has scanned — how many sites hold each grade from A+ to F. Use it to say where one site’s grade sits relative to the web (e.g. “a B beats X% of scanned sites”). Keyless, no arguments.
