About AI Agent in Browser

A developer tool for WebMCP. It lists the tools a page registers through document.modelContext, lets you run them by hand, and lets a Gemini agent call them for you, with a readable transcript. Requires Chrome with the WebMCP flag or origin trial enabled on the page. A fork of Model Context Tool Inspector (Apache-2.0). Not affiliated with Google.
