RU-1006: Keyless MCP endpoint does not serve this tool

The call reached the keyless MCP endpoint (no API key) asking for a tool that endpoint does not serve. The keyless endpoint serves the read-only outage tools over public measurement data; every tool that reads or changes an account stays on the keyed endpoint.

On the wire

Ships with HTTP status 403, carrying "code": "RU-1006" in the response body alongside the human-readable error message. Existing fields are never replaced by the code: it is additive.

Common causes

  • An MCP client configured against the keyless endpoint tried an account tool such as list_checks or create_check.
  • A client copied a tool name from the keyed API reference while pointed at the keyless URL.

How to fix it

  1. Generate an API key from your dashboard's API & MCP access section.
  2. Point the client at the keyed MCP endpoint with `Authorization: Bearer <api key>` and retry.
  3. To use the keyless endpoint, call only the outage tools it lists in tools/list.
