Feedthrough MCP Server

Debug with AI - from inside your app. Feedthrough injects a lightweight debug bridge into any running web page, then exposes everything - DOM state, console logs, network requests, and user interactions - as MCP tools. Any MCP-compatible AI agent can inspect and drive the page conversationally, in real time. It runs locally over stdio via the published package.

People connecting browser automation tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Feedthrough

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add feedthrough-feedthrough -- npx -y @feedthrough/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "feedthrough-feedthrough": {
      "command": "npx",
      "args": [
        "-y",
        "@feedthrough/mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
