chrome-devtools-mcp and firefox-devtools-mcp
These are complements that serve the same automation purpose across different browsers—developers would use them together to achieve cross-browser testing and control, with Chrome DevTools providing vastly more mature tooling through its established Remote Debugging Protocol implementation compared to Firefox's nascent MCP server.

Chrome DevTools for coding agents
This project helps AI coding assistants like Gemini or Copilot interact with a live Chrome browser. It enables your assistant to automate browser tasks, debug web pages, and analyze website performance by providing real-time control and inspection. Web developers, quality assurance engineers, and AI developers building agent-based tools would use this.

Model Context Protocol server for Firefox DevTools - enables AI assistants to inspect and control Firefox browser through the Remote Debugging Protocol
This tool helps AI assistants like Claude automate tasks in Firefox. It allows an AI to control a Firefox browser to perform actions like navigating pages, clicking elements, filling forms, taking screenshots, and inspecting network requests and console messages. This is useful for AI developers creating agents that need to interact with websites through a real browser.
