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
- Run it in a separate browser profile without your logged-in accounts.
- Pin the version you reviewed instead of always installing the latest release.
- Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.
- Maintained by 0xMassi on GitHub, 2,416 stars and 239 forks. Popularity is not proof of safety.
- Last code change: Oct 30, 2026.
- Open-source license: AGPL-3.0.
