FAQ from Pandora's Shell

Is it safe to use Pandora's Shell?

No. This server grants AI assistants unrestricted ability to execute terminal commands with your user privileges. Only use in controlled environments like virtual machines (VMs) or development systems you can afford to rebuild. Never use on production systems or machines with sensitive data.

What are the system requirements?

Python 3.10 or higher, Git, and uv for package management. Claude Desktop with an active Claude Pro/Enterprise subscription is used for the configuration example.

How do I configure Pandora's Shell for Claude Desktop?

Create or edit claude_desktop_config.json in the correct configuration directory (e.g., %APPDATA%\Claude\ on Windows or ~/Library/Application Support/Claude/ on macOS). Set the command to the Python interpreter inside your virtual environment and args to the executor script path, with PYTHONPATH set to the src directory.

How do I verify the server is running successfully?

Restart Claude Desktop completely, then click the 🔌 icon to check if "pandoras-shell" appears in the Installed MCP Servers list. If not, inspect the MCP logs (e.g., %APPDATA%\Claude\Logs\mcp*.log on Windows).

What happens if a command times out?

The server sets a 5-minute timeout for command execution. If the timeout is reached, the command is terminated and error handling is applied.
