Security Notes

The `mcp-interviewer` tool itself does not contain obvious vulnerabilities like `eval` or hardcoded secrets. Its primary security risk stems from its intended function: executing user-provided MCP server commands in a child process and invoking their tools. This inherently involves interacting with potentially untrusted external code. The project demonstrates strong security awareness by explicitly warning users about these risks in the README and CLI (e.g., `--test` flag requires `accept-risk` confirmation) and recommending running target servers in isolated containers. Adherence to these best practices is crucial for safe operation.
