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
- 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 modelcontextprotocol on GitHub, 3,757 stars and 1,112 forks. Popularity is not proof of safety.
- Last code change: Nov 1, 2026.
- Open-source license: MIT.
