Firefox DevTools MCP is a Model Context Protocol server that automates Firefox using WebDriver BiDi through Selenium. It enables AI assistants like Claude to control browser actions such as navigation, screenshots, and network monitoring. It integrates with various MCP clients including Claude Code, Cursor, and Cline.

firefox-devtools-mcp sits in the Browser Automation category, so it is usually better judged by workflow fit, deployment style, and team needs than by isolated features alone. Based on the available metadata, it leans most clearly toward Automate Firefox via WebDriver BiDi. A representative use case is AI-driven browser automation for testing and scraping. The listed license is MIT. GitHub stars are currently 514. Relevant tags include claude-code, firefox.
