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 who work with agentic web, browser automation and dom inspector and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Feedthrough

before you install - you'll need

FEEDTHROUGH_PORT

Environment variables documented in the project's README - it lists which are required and which have defaults.

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

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package @feedthrough/mcp - published under the repo owner's npm scope (@feedthrough)

registry namespace io.github.feedthrough is GitHub-verified and matches the repo owner

06 · Feedthrough FAQ

What is Feedthrough?

Is Feedthrough still maintained?

Yes - as of 2026-09-18, its last commit was 2026-09-04 and it shipped 1 release in the last 90 days. We re-verify nightly.

How do I install Feedthrough?

Run `npx -y @feedthrough/mcp`. The README documents one environment variable (FEEDTHROUGH_PORT) to set first. You can also paste the ready-made client config above.

Does Feedthrough run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
