          MCP tools/call get-full-api-description against https://api.docs.cpanel.net/mcp, after

      x-calling-conventions:
        outcome_field: result.status
        outcome_note: >-
          Every operation answers HTTP 200. Failure is reported as result.status == 0 with
          result.errors[]. Branching on the HTTP status code will read every failure as a success.
        booleans: Integers 1 and 0. Literal true/false are not accepted.
        ports: 2083 (secure cPanel), 2082 (unsecure), 2096/2095 (Webmail). Wrong port returns "Permission denied".
        auth_header: 'Authorization: cpanel <username>:<APITOKEN>' 
        pagination: api.paginate=1 with api.paginate_start / api.paginate_size / api.paginate_page (off by default)
        filtering: api.filter=1 with api.filter_column / api.filter_term / api.filter_type
        sorting: api.sort=1 with api.sort_column / api.sort_method / api.sort_reverse
        sorting_hazard: Sorting numeric values without api.sort_method makes the function fail.

        note: >-
          cPanel does not define this vocabulary in its developer portal (searched 2026-09-05),
          so it is read literally. No reversal WINDOW is published for any operation.
