CoreDash API
JSON-RPC 2.0 API for CoreDash real user monitoring data, sent as POST to https://app.coredash.app/api/mcp (the same endpoint as the CoreDash MCP server, registry io.github.corewebvitals/coredash). Requests need a project-scoped Bearer key prefixed cdk_; the documented tools are get_metrics, get_timeseries and get_histogram. A separate Agency API uses a master key. No OpenAPI is published; anonymous tools/list returns 401.
