How to Use the Liveblocks MCP in VS Code Copilot

Q: How do we share the Liveblocks configuration in VS Code Copilot?

You write a .vscode/mcp.json file containing the server details and commit it to your repository. Everyone on the team gets instant access to tools like listrooms in Copilot Chat.

Q: Can my team use the Liveblocks MCP Server in VS Code Copilot to inspect active users?

Yes. Your developers can ask Copilot to run listactiveusers to see who is currently connected to a specific collaborative space during live testing.

Q: How does VS Code Copilot handle Liveblocks user authorization?

Copilot executes authorizeuser to generate temporary access tokens. This lets your team test client-side room connections with realistic security profiles.

Q: Can we modify collaborative storage structures?

Yes. Copilot uses initializestorage to set up schemas and patchstorage to apply updates, allowing you to test state mutations directly from the chat.

Team-wide Liveblocks workflows inside VS Code Copilot

Commit your `.vscode/mcp.json` to your repository so your entire engineering team can access the same Liveblocks MCP Server. Your team can ask Copilot to inspect live rooms using `get_room` or list active environments with `list_rooms` without sharing manual scripts. This shared setup ensures everyone can debug live multiplayer states instantly. Whether verifying permissions or checking active rooms, the whole team uses the same secure endpoints.

Debug Yjs documents with Copilot Chat

Dealing with binary Yjs updates is notoriously difficult to debug. This MCP Server lets your Copilot agent call `get_ydoc` to convert the binary state into a readable JSON format directly inside your chat panel. If you need to push a quick fix, tell Copilot to execute `update_ydoc` with the correct binary payload. It saves you from writing custom local debugging tools just to see what is happening in your shared document.

Manage threads and rooms directly from your editor

When developing comment systems, you need to verify thread states. Copilot can list active discussions using `list_threads` or create a test conversation using `create_thread` to check if your UI renders comments correctly. You can also manage room lifecycles during local testing. Use `create_room` to spin up fresh testing environments and `delete_room` to clean them up when you are done.

Setup guide

Set up Liveblocks MCP in VS Code Copilot

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
2

Add the Liveblocks MCP

Paste the JSON snippet shown on the right into your .vscode/mcp.json. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Switch to Agent mode

Open Copilot Chat (Cmd+Shift+I / Ctrl+Shift+I) and switch to Agent mode using the dropdown. MCP tools are only available in Agent mode — they do not appear in Edit or Ask modes.
4

Verify the connection

In the Copilot Chat input, type # to list available tools. You should see the Liveblocks tools listed. Try asking: "List my recent Liveblocks transactions" and Copilot will invoke them automatically.

.vscode/mcp.json

{
  "mcpServers": {
    "liveblocks-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
