Share live room management across your team

The `list_rooms` tool allows your team's development agent to query and filter active collaborative environments directly inside the editor. By committing the MCP configuration to your repository, every engineer gets instant access to the same live environment data. This keeps everyone aligned on which rooms are active during testing. If a team member needs to modify permissions on a shared testing room, the agent runs `update_room` to apply the changes. There is no need for team members to share administrative credentials or log into a separate console. The agent handles the updates securely using your team's shared configuration.

Inspect and patch shared storage on the fly

The `get_storage` tool retrieves the live LSON or JSON storage tree of a room so your team can verify data consistency during collaborative sessions. When multiple developers are testing concurrent updates, the agent can inspect the exact state of the room to identify race conditions. If you need to fix a broken state during a live test, the agent can run `patch_storage` to apply JSON Patch operations directly. This lets you correct data anomalies in your testing environments without writing custom database scripts. It keeps your team's development velocity high.

Monitor real-time presence and events

The `list_active_users` tool lets your development agent see exactly who is connected to a collaborative room in real time. This is incredibly useful for debugging presence-related bugs, like ghost cursors or stale connection states, during team-wide testing sessions. Your agent can also use `broadcast_event` to simulate user actions and events across the room. This allows you to verify that your frontend event handlers are reacting correctly to incoming payloads under real-world conditions. It provides a reliable way to stress-test your collaborative features before deployment.

Setup guide
