  Crosswalk binding the DERIVED candidate MCP tool surface (mcp/mx-mcp.yml) to
  its backing MX Platform API OpenAPI operations. There is no published MX MCP
  server or GraphQL surface, so every tool maps 1:1 to a REST operationId with
  high confidence (the tool inherits that operation's parameters as its real
  inputSchema). rest_only captures the ~160 additional Platform API operations
  not surfaced as candidate tools.
