Claude Firefox

概要

This project provides a Model Context Protocol (MCP) server that establishes a robust bridge between the Claude Code CLI and the Firefox browser. Utilizing a Deno-based server and a dedicated Firefox extension, it allows Claude to execute a wide array of browser interactions. Capabilities include capturing screenshots, navigating to specified URLs, reading detailed page content via the accessibility tree, interacting with elements through clicks and typing, filling out forms, and comprehensive tab management. The architecture relies on a standard I/O connection for MCP communication with Claude Code and a WebSocket connection to the Firefox extension, facilitating sophisticated AI-driven browser automation and orchestration.
