## FAQ

### Does it restrict file access to a working directory?

File tools and save_as paths are checked against the working directory unless MCP_ALLOW_SYSTEM_ACCESS=1 is set, but executed Python code itself is not sandboxed.

### How do I configure it in Claude Desktop?

Add the mcp-python-interpreter entry to claude_desktop_config.json using uvx with --dir and --python-path arguments, then restart Claude Desktop.
