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 use a code-hosting token (GitHub/GitLab).
  • Based on its description and topics, it likely needs to run shell commands.

Before you install

  1. Use a fine-grained token limited to the repos it needs.
  2. Keep tool-call approval on, and run it in a container if you can.
  3. Pin the version you reviewed instead of always installing the latest release.
  4. Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.
