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 run shell commands.
Before you install
- Keep tool-call approval on, and run it in a container if you can.
- 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 Atomburstofficial on GitHub, 170 stars and 9 forks. Popularity is not proof of safety.
- Last code change: Sep 21, 2026.
- Open-source license: MIT.
