Summary
The smallest surface there is: one tool, a command, and a directory to run it in.
There is nothing to learn — the interface is a command string and where to run it — which makes this the general-purpose fallback for the many jobs that have no dedicated server. The tool describes security restrictions without enumerating which, so treat the boundary as yours to establish before pointing an agent at a machine that matters.
What it is
A one-tool server that executes a terminal command in a specified working directory, with security restrictions applied by the server.
What you get
- Any shell command executed on the machine running the server, through a single call
- A workingDir argument on that call, so the command runs where you meant it to rather than wherever the server started
Requirements
No account and no key. What it does need is a machine you are content to let it run commands on: the tool takes a command and a workingDir and executes them locally.
Setup effort
One command — npx -y @smithery/cli install @weidwonder/terminal-mcp-server --client claude
