  IMPORTANT — these are HundredX's own INTERNAL analyst tooling, not a customer-facing
  agent product. The hostnames (BigQuery, Jupyter, strategy-team, dag-ops) and the
  Google-federated OAuth scopes (bigquery.readonly, cloud-platform) describe employee
  access to HundredX's warehouse and notebooks. They are publicly reachable and they
  publish standards-compliant discovery metadata, which is why they are recorded here,
  but HundredX publishes no developer documentation for them and no public MCP product.
  Do not read this artifact as "HundredX ships an MCP server customers can call."

tool_crosswalk: null
tool_crosswalk_reason: >-
  No ToolCrosswalk is emitted. A crosswalk binds MCP tools to backing OpenAPI operationIds,
  and HundredX publishes neither an OpenAPI nor a GraphQL surface, and the live MCP tool
  lists are OAuth-gated. There is nothing on either side of the mapping to bind.
