Firefox Devtools

Firefox DevTools MCP is a Model Context Protocol server designed for automating the Firefox browser through WebDriver BiDi, often using the Selenium WebDriver. It allows developers, testers, and automation engineers to programmatically control Firefox for tasks like navigation, input, screenshotting, network monitoring, extension management, profiling, and running custom scripts. The tool is for those looking for deep browser automation via MCP-compatible clients such as Claude Code, Cursor, and others, and works locally with a Firefox installation.
