The Model Context Protocol lets you plug arbitrary third-party servers into
your AI agent — and each one you install gets to run code, touch your
filesystem, and shape what the model does next, based entirely on tool
descriptions the agent trusts blindly. `npx some-random-mcp-server` is the
new `curl | sh`, except the thing running it also has your Claude/Cursor
session's credentials.

**mcp-sentinel scans an MCP server — source code or a live running
instance — and tells you exactly what it can do and where that's
dangerous**, before you add it to your config.

```
$ mcp-sentinel scan ./some-mcp-server
