  • Broadcasting events via `broadcast-event` sends real-time messages to all connected users in a room immediately.

Privacy notes

  • Room metadata, collaborative storage content, Yjs document state, thread and comment content, and user notification settings from your Liveblocks project are surfaced in Claude's context.
  • Your `LIVEBLOCKS_SECRET_KEY` grants full project API access — keep it out of source control and only add it to a trusted MCP config after selecting a verified install source.

Prerequisites

  • A Liveblocks account — sign up at liveblocks.io.

About this resource

Overview

The Liveblocks MCP Server is the official Model Context Protocol server from Liveblocks, the platform for building real-time collaborative features. It provides 39 tools covering rooms, collaborative storage, Yjs documents, threads, comments, inbox notifications, and notification settings — giving Claude direct management access to your Liveblocks collaboration infrastructure. Apache-2.0 licensed.

Note: This entry is not marked installable because the upstream MCP server is currently documented as a direct GitHub install rather than a versioned package registry artifact. Wait for a published package, signed release, or maintainer-reviewed immutable commit pin before adding it to Claude.

Key capabilities

  • Rooms — create, get, update, and delete collaboration rooms; get active users.
  • Events — broadcast real-time events to all users in a room.
  • Storage — retrieve collaborative storage documents.
  • Yjs documents — get Yjs document state from rooms.
  • Threads — create, manage, and resolve comment threads.
  • Comments — create, edit, and react to comments within threads.
  • Inbox notifications — get, trigger, and mark notifications.
  • Notification settings — update and retrieve notification preferences.

Liveblocks MCP is the only real-time collaboration infrastructure MCP with integrated comment threads, Yjs document access, and inbox notification management.

Installation

This entry intentionally does not provide a copyable install command yet. The upstream documentation currently uses a mutable GitHub package specifier, which can execute whatever code is on the repository default branch at install time. Use this MCP server only after Liveblocks publishes a versioned package, signed release, or immutable commit-pinned install source that you have reviewed and trust.

Get your secret key from Dashboard → Project Settings → API Keys → Secret key (format: sk_prod_... or sk_dev_...).

Requirements

  • A Liveblocks account with at least one project.
  • Secret key (sk_...) from the Liveblocks Dashboard.
  • A reviewed, immutable install source for the MCP server.
  • An MCP client (Claude Code or Claude Desktop).

Security

  • LIVEBLOCKS_SECRET_KEY grants full project API access — never commit it or share it.
  • Broadcasting events is instant — confirm the target room before triggering.
  • Use separate sk_dev_... keys for development to avoid affecting production rooms.
  • Avoid running mutable GitHub package specifiers directly with npx; prefer a versioned package, signed release, or reviewed immutable commit pin.

Source Verification Notes

Verified on 2026-06-18:

  • Official repository liveblocks/liveblocks-mcp-server (Apache-2.0) documents LIVEBLOCKS_SECRET_KEY configuration (format sk_...), all 39 tools across rooms, events, storage, Yjs, threads, comments, inbox notifications, and notification settings.
  • Claude Code MCP documentation at code.claude.com/docs/en/mcp describes the stdio connector pattern used above.

Safety notes✓Tools can create, update, and delete rooms, threads, and comments — changes affect your live Liveblocks collaboration infrastructure. Broadcasting events via `broadcast-event` sends real-time messages to all connected users in a room immediately.✓The server runs entirely offline — no network requests are made during queries. All skill content is bundled with the npm package.✓Mutation operations (write, update, delete) require `confirm_write=true` to be passed explicitly, adding a confirmation step before any destructive action. The API key scope determines what operations are available — use least-privilege scopes for your use case.✓Tools can create, update, and delete projects, issues, wikis, and pull requests — changes affect your live Backlog space. Use `ENABLE_TOOLSETS` to restrict which tool groups are available if you only need read access.
Privacy notes✓Room metadata, collaborative storage content, Yjs document state, thread and comment content, and user notification settings from your Liveblocks project are surfaced in Claude's context. Your `LIVEBLOCKS_SECRET_KEY` grants full project API access — keep it out of source control and only add it to a trusted MCP config after selecting a verified install source.✓No API keys, user data, or query content is sent to any external service. All lookups happen locally against the bundled skill snapshot.✓User records, database documents, function logs, team memberships, and messaging data from your Appwrite project are surfaced in Claude's context. Your `APPWRITE_API_KEY` grants project-level access — keep it in the MCP config env and never commit it to version control.✓Issue content, comments, wiki pages, pull request details, and user information from your Backlog space are surfaced in Claude's context.
