How do I install the cli mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

The recorded environment keys are `ALLOWED_DIR`, `ALLOWED_COMMANDS`, `ALLOWED_FLAGS`, `MAX_COMMAND_LENGTH`, `COMMAND_TIMEOUT`, `ALLOW_SHELL_OPERATORS`. Keep credentials outside committed files and confirm the configuration required by your installed version.
