summary: >-
  Crosswalk binding each candidate MCP tool to its backing Gateway V3 OpenAPI
  operationId. Because the MCP surface is derived 1:1 from the OpenAPI (no
  published server, no GraphQL), every tool maps with high confidence to exactly
  one REST operation and inherits that operation's parameters + requestBody as its
  real inputSchema. No mcp_only tools; the Direct PCI spec re-exposes a subset of
  the same operations on secure.tillpayments.com.
