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.

Before you install

  2. Read the tool list or scripts before the first run, and keep approval prompts on for actions that write, send or delete.
