description: >-
  Entur publishes, in its own GitHub org, a Java/Spring AI MCP server described as a
  "poc mcp using journey-planner and geocoder apis". It wraps the Journey Planner v3
  (OpenTripPlanner transmodel GraphQL), the Geocoder and the Mobility v2 GraphQL APIs,
  and ships embedded MCP App UIs (departure board, trip map, nearby stops/mobility maps).
  The README documents running it as a stateless HTTP server at http://localhost:8080/mcp.
  The repo's Helm values name hosted ingresses (opentripplanner-mcp.entur.io for prd,
  opentripplanner-mcp.staging.entur.io for tst); both answered 403 Forbidden to an
  unauthenticated MCP initialize POST on 2026-10-09, so the hosted endpoint is not
  publicly reachable.
