  openapi/greenbrier-cos-*-openapi.yml. Searched for a first-party Greenbrier MCP server on
  2026-09-12 - gbrx.com, every product host, npm and PyPI - and found none.
status: candidate
note: >-
  Greenbrier ships no MCP server, hosted or local. This is a CANDIDATE tool list derived from the
  operations Greenbrier actually serves, offered as a design, not as something an agent can call
  today. No endpoint is asserted because none exists; inventing one would read as a verified agent
  surface and there is nothing to verify. Every tool below maps 1:1 onto a real, anonymously
  callable operation in the specs in openapi/, so this list is implementable by anyone without
  Greenbrier's involvement.
