Add this to your Claude Desktop config file. Find it at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS.

What this does

freema/firefox-devtools-mcp exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation. That makes it useful when you want Claude to reach into live web pages and browser sessions without copy-pasting context every turn.

Common use cases

  • Navigate, fill forms, and scrape pages on demand from Claude
  • Test UI flows or capture screenshots as part of a debugging session
  • Reach data behind logins or interactive pages that simple HTTP fetch cannot
