note: >-
  Channel99 runs three machine surfaces over the same marketing-performance data set. Only one
  of them - the Pulsar REST API - publishes a readable contract. This crosswalk records what can
  honestly be bound and, just as importantly, what cannot: the MCP tool list is OAuth-gated and
  the GraphQL endpoint is 401 on introspection, so NO tool names are invented here. crosswalk[]
  is deliberately empty rather than speculatively populated.

      The Swagger UI and its embedded OpenAPI document are served anonymously at

    note: >-
      Channel99's own MCP documentation states the MCP services are built over the same schema
      as the Snowflake share (fact tables Visit, Pageview, Impression plus ad, audience, company,
      vendor and channel dimensions) - the same entity set the Pulsar REST operations return.

  mcp_tools: null
  bound: 0
  mcp_only: 0
  rest_only: 17
  bindable: false
  bindable_reason: >-
    A crosswalk needs one enumerable tool list. Channel99's is behind OAuth and no tool manifest
    is published anywhere public, so 0 of 17 REST operations can be bound to a named tool today.
    Re-run this artifact after an authenticated tools/list and the bindings will be real.
