What is the Liveblocks MCP Server?

Connect your Liveblocks account to any AI agent to orchestrate multiplayer experiences and real-time collaboration features through natural language.

What you can do

  • Room Management — List, create, update, and delete rooms to manage your application's collaborative spaces.
  • User Authentication — Generate access tokens and identify users with specific permissions using authorize_user and identify_user.
  • Collaborative Storage — Inspect and patch room storage state or manage Yjs documents for shared editing.
  • Comments & Threads — Query, create, and resolve comment threads to keep track of team discussions within rooms.
  • Real-time Presence — List active users in a room or broadcast custom events to connected clients.

How it works

  1. Subscribe to this server
  2. Enter your Liveblocks Secret Key
  3. Start managing your real-time infrastructure from Claude, Cursor, or any MCP-compatible client

Who is this for?

  • Full-stack Developers — quickly debug room storage, manage user permissions, or clear stale rooms without leaving the terminal or IDE.
  • Product Managers — monitor active collaboration sessions and review comment threads across different project rooms.
  • DevOps Engineers — automate the provisioning of collaborative environments and manage access rules programmatically.

FAQ

Frequently asked questions

01

How can I filter rooms by specific metadata using the AI?

You can ask the agent to use the list_rooms tool and provide a JSON string in the metadata parameter. For example, ask to 'List rooms where the project metadata is alpha'.

02

Can I generate a temporary access token for a user to join a room?

Yes. Use the authorize_user tool. Provide the Room ID and User ID, and the agent will return a token that grants access to that specific room.

03

Is it possible to permanently delete a room and its data?

Yes, the delete_room tool allows you to permanently remove a room and all associated storage, comments, and metadata. Use this with caution as it is irreversible.

04

How does LangChain connect to MCP servers?

Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.

05

Which LangChain agent types work with MCP?

All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.

06

Can I trace MCP tool calls in LangSmith?

Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
