Feedthrough
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.

Many physics and chemistry experiments run inside a sealed vacuum chamber, with all the air pumped out so nothing contaminates the experiment. The catch: you still need to control instruments inside the chamber and read their measurements, and the smallest air leak ruins the run. A feedthrough is the part that solves this — a specially engineered connector that carries electrical signals through the chamber wall while keeping the vacuum perfectly intact. You can't reach inside, but the feedthrough lets you observe and control what's happening in there anyway.
