The project directly handles AWS credentials files, which are highly sensitive. The implementation includes masking of secret keys and session tokens for output/logging. It runs as a local MCP server using stdio transport, limiting direct network exposure to external agents. The README explicitly warns against sending sensitive information to LLMs when integrating with agents. No 'eval' or obvious shell injection points found. File operations are handled using 'pathlib' and 'os.chmod', which are generally safe but require careful permission management by the user for the credentials file itself (as noted in section 9 of the README).
