Zen Mcp

sh6drack/zen-mcp

This connects Claude to Zen Browser through WebDriver BiDi over WebSocket, no Selenium or Playwright needed. You get 20 tools covering navigation, tab management, form filling with proper event dispatch for React and Vue apps, screenshots, page text extraction, and JavaScript evaluation. It handles auto-reconnect with exponential backoff and zombie session recovery when connections drop. Point it at Zen running with the remote debugging flag on port 9222 and you can automate browsing workflows directly from Claude Desktop or Cursor. Useful if you're already running Zen and want Claude to drive web interactions without spinning up a separate automation framework.

Zen Browser remote debugging port

Readme

zen-mcp

The first MCP server for Zen Browser. Automate Zen from Claude Code, Cursor, or any MCP client.

No Selenium. No Playwright. No browser drivers. Just WebSocket.

Setup (2 minutes)

1. Start Zen with remote debugging

/Applications/Zen.app/Contents/MacOS/zen --remote-debugging-port 9222

Pro tip: Add alias zen='open /Applications/Zen.app --args --remote-debugging-port 9222' to your shell config. Then just run zen.

2. Add to Claude Code

# Option A: npm (recommended)
npm install -g zen-mcp

# Option B: Clone
git clone https://github.com/sh6drack/zen-mcp.git && cd zen-mcp && npm install

Add to ~/.claude/mcp_servers.json:

{
  "mcpServers": {
    "zen-browser": {
      "command": "zen-mcp"
    }
  }
}

If you cloned instead of npm install, use "command": "node", "args": ["/absolute/path/to/zen-mcp/server.mjs"]

Add to ~/.claude/settings.json:

{
  "permissions": {
    "allow": ["mcp__zen-browser__*"]
  }
}

That's it. Start a new Claude Code session and the zen_* tools are available.
