What the code does
We read the source, 9 h ago · rules 3dff92dd89df
What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
server_host_key: str | None = Field(default=None, description="Remote server SSH host key in OpenSSH format (as would appear in ~/.ssh/known_hosts). When provided, the server's host key must match exactly.")

This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
