What is the Liveblocks (Collaborative) MCP Server?
Connect your Liveblocks account to any AI agent to orchestrate real-time collaborative experiences and manage infrastructure through natural conversation.
What you can do
- Room Lifecycle — Create, list, update, and delete collaborative rooms with custom metadata and access controls.
- Presence & Interaction — Monitor active users in any room, set ephemeral presence, and broadcast custom events to connected clients.
- Data Synchronization — Retrieve and patch room storage or Yjs documents to manage shared state across collaborative sessions.
- Comments & Feedback — Manage collaborative threads, create new discussions, and resolve existing ones to streamline team feedback.
- User Identity — Authorize and identify users with specific permissions and group assignments via secure token generation.
How it works
- Subscribe to this server
- Enter your Liveblocks Secret Key from the dashboard
- Start managing your real-time infrastructure from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Product Managers — Monitor active collaboration sessions and review user feedback threads without leaving the chat interface.
- Full-stack Developers — Debug room storage, inspect Yjs document states, and manage room permissions directly from the IDE.
- Support Teams — Quickly identify active users in a room and verify room configurations to assist customers in real-time.

Frequently asked questions
How can I see which users are currently active in a specific collaboration room?
You can use the list_active_users tool by providing the Room ID. The agent will return a list of all users currently connected to that room, including their connection IDs and associated info.
Is it possible to inspect or modify the shared state of a room from the AI?
Yes! Use get_storage to retrieve the current LSON/JSON storage tree or patch_storage to update specific keys in the room's shared state. For Yjs-based rooms, you can use get_ydoc and update_ydoc.
Can I manage user comments and discussion threads through this integration?
Absolutely. You can use list_threads to see all discussions in a room, create_thread to start a new one, and resolve_thread to mark a discussion as completed.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Liveblocks (Collaborative) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
