Before you install Firefox Devtools MCP

Firefox Devtools MCP has not been scanned by AgenticMart yet. It has no open-source license we can detect, so it can only be scanned once the maintainer claims it. Until then, here is what it can likely access and what to check before you install it.

What it can access

  • An MCP server is a program your AI app starts and talks to. A local one runs with your user's permissions: it can see the files, environment variables and network your account can.
  • Based on its description and topics, it likely needs to control a web browser (visit sites, fill in and submit forms).

Before you install

  1. Run it in a separate browser profile without your logged-in accounts.
  2. Pin the version you reviewed instead of always installing the latest release.
  3. Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.
  • Maintained by mozilla on GitHub, 534 stars and 73 forks. Popularity is not proof of safety.
  • Last code change: Oct 30, 2026.
  • No open-source license detected: check the repository before using it commercially.
