description: Candidate MCP tool surface derived from the Apperio OpenAPI operations. Apperio publishes
  no official hosted/remote MCP server; this is a governance starting point mapping each REST operation
  to a prospective MCP tool. Operations have no operationIds in the spec, so tools are keyed by method
