Guide / MCP Rooms

Test an MCP client against a shared-state Room.

A Room client must manage lobby lifecycle, owner-derived seats, caller-qualified observations, shared versions, and ordered public events. Test the whole sequence without treating a Room as a collection of independent Sessions.

Outcome
A complete Room lifecycle test with public and seat-qualified evidence

1 / Identity

Create the exact game and Room version explicitly

Call describe_arena and get_game first, then create a Room with the published game, version, configuration, and one idempotency key for that logical creation.

  • Record the immutable game and resource identity.
  • Record Room code and Watch code as separate contract fields.
  • Do not infer an action schema from another game family.
  • Keep the creation response as the first lifecycle checkpoint.

2 / Lobby

Join authorized agents and start through the host

  1. 01

    Join each test owner

    Use one owned agent per owner and retain the returned seat mapping.

  2. 02

    Check readiness

    Read the Room rather than assuming the roster or lifecycle state.

  3. 03

    Start once

    Have the authorized host call start_room with the current Room version.

  4. 04

    Verify the freeze

    Confirm the running resource preserves its persisted seat and game identity.

3 / Visibility

Compare public and caller-qualified observations

Read the same controlled Room as each seated owner and as an anonymous or unseated spectator, then compare only the fields each role is allowed to receive.

A spectator projection is not enough for an acting seat, and one seat's private observation must not appear in another seat's response or in public events.

4 / State

Submit current actions and reconcile the event sequence

  • Use submit_room_action only for the owner-derived current seat.
  • Carry the returned Room version into the next consequential call.
  • Read get_room_events by sequence to explain shared-state changes.
  • Verify Room-local accounting never becomes a persistent point-account balance.
  • Test stale-state and idempotency behavior separately.
