note: >-
  Customers Bank exposes the ReadMe GENERIC MCP server, whose tools are spec/documentation
  meta-tools rather than one tool per API operation. There is therefore no 1:1 tool->operationId
  binding; instead a single execute-request tool can invoke ANY of the 211 REST operations by
  HAR request. This crosswalk records that divergence honestly rather than fabricating per-operation tools.
surfaces:
  openapi:
    files: 10
    operations: 211
    gated: false
    note: OpenAPI 3.0.1 specs are public via the ReadMe portal; the live API host is partner-gated (OAuth2).
  mcp:
    url: https://cubiapi.readme.io/mcp
    gated: false
    note: tools/list returns anonymously; execute-request against the live API requires an OAuth2 Bearer token.

crosswalk: []
mcp_only:
  - tool: list-endpoints
    reason: Meta-tool that enumerates spec paths/methods; not backed by a single REST operation.
  - tool: get-endpoint
    reason: Meta-tool returning spec detail for one path/method; reads the OpenAPI, does not call the API.
  - tool: search-endpoints
    reason: Meta-tool that searches across all specs; no single backing operation.
  - tool: list-specs
    reason: Enumerates the 10 OpenAPI documents; no backing REST operation.
  - tool: search
    reason: Documentation search; no backing REST operation.
  - tool: fetch
    reason: Documentation content retrieval by id; no backing REST operation.
  - tool: execute-request
    reason: >-
      Universal HAR executor. It can invoke any of the 211 REST operations (accounts, ach,
      wires, instant payments, transfers, consumer lending, partners, webhooks, security),
      so it maps to ALL operations rather than one; its real input contract is the target
      operation's parameters + requestBody in the referenced OpenAPI.
rest_only:
  note: >-
    All 211 REST operations are reachable only through the generic execute-request tool; none
    has a dedicated MCP tool. Capability groups below are addressable via execute-request.
  groups:
    - {api: accounts, operations: 29}
    - {api: ach, operations: 20}
    - {api: consumerlending, operations: 12}
    - {api: instantpayments, operations: 31}
    - {api: itoperations, operations: 9}
    - {api: partners, operations: 35}
    - {api: security, operations: 3}
    - {api: transfers, operations: 34}
    - {api: webhooks, operations: 17}
