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 — it connects to the bridge automatically
3. Your AI can now read and edit your script live through the tools below

Install

npm install -g 247afk-mcp

Get Started

Codex CLI

codex mcp add 247afk-mcp -- npx -y 247afk-mcp

Gemini CLI

gemini mcp add 247afk-mcp npx "-y 247afk-mcp"

Claude Code

claude mcp add 247afk-mcp -- npx -y 247afk-mcp

Claude Desktop

{
  "mcpServers": {
    "247afk-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "247afk-mcp"
      ]
    }
  }
}

Manual

1. Copy configuration below
2. Add it to your MCP client configuration
3. Follow your client's specific setup instructions
4. Restart your MCP client to apply changes

Configuration

{
  "mcpServers": {
    "247afk-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "247afk-mcp"
      ]
