The core application code is relatively safe, reading API keys from environment variables and using standard libraries. No direct 'eval' or command injection vulnerabilities are apparent. However, the setup documentation and example configuration files ('claude_desktop_config.json', 'SETUP_CLAUDE_DESKTOP.md') explicitly show users how to embed the 'POLYGON_API_KEY' directly into the configuration file's 'args' array or 'env' dictionary. While a security note is present, this practice can lead to accidental exposure of sensitive API keys if the configuration file is committed to version control or shared improperly.
