summary: |
  Cash App publishes a docs-search MCP server (single searchDocs tool) alongside a large REST
  surface (100 operations across the Cash App Pay Partner API and Afterpay Global API). The MCP
  tool and the REST operations do NOT overlap: searchDocs is a documentation retrieval tool with
  no backing REST operation, and every REST operation is exposed only over HTTP. This crosswalk
  records that divergence honestly rather than fabricating REST bindings for a docs tool.
