247afk Block Editor MCP Server

Lets AI assistants (Claude Desktop, Cline, Cursor, and any MCP-compatible client) build and edit block editor scripts in real time.

How it works

1. The MCP server runs locally and starts a WebSocket bridge on 127.0.0.1:3002

2. Open a script in the 247afk editor, the site will connect to your websocket.

3. Your ai assistant can now use the MCP server to make changes in scripts.
