Frequently asked questions

What are the prerequisites?

Python 3.13 (e.g., via `mise`) and `uv` (e.g., via Homebrew).

How do I add a new tool?

Create a shell script in the `./commands/` directory (e.g., `command_name.sh`) and reload the MCP server.

What precautions should I take?

Each script must include a shebang, have execute permission (auto‑adjusted), and be intended for local use only. Only place scripts you fully understand.

How do I change the working directory for script execution?

Set the `COMMAND_DIRECTORY` environment variable in your MCP client’s configuration for the server entry.
