Deputy

Deputy is a browser tool extension that lets AI coding agents read pages and fill forms.

Deputy is a browser extension and Model Context Protocol plugin that connects coding agents like Claude Code, Codex, Gemini CLI, Copilot, and Cursor to your open browser. It turns the web page in front of you into typed tools, allowing agents to read pages, fill forms, and click elements without taking screenshots. The system runs locally on your computer through Node.js, keeping page data between your browser and the local program. The free tier provides basic page reading and form filling with ten tools, while the pro tier adds screenshots, tab management, console access, network tools, and hosted models. It supports multiple Chromium browsers and integrates with a wide range of AI development agents.
