The server uses environment variables for sensitive credentials (email, CalDAV, API keys), which is a good practice. It relies on standard, well-maintained libraries for network interactions (IMAP, SMTP, CalDAV). The email body cleaning function `_clean_email_body` is complex with multiple regex operations, which can be prone to edge cases, but aims to reduce the amount of data sent to the LLM. The primary security consideration lies in giving an LLM access to email and calendar actions; misconfigured or unconstrained prompts could lead to unintended email sending or event creation. No direct `eval` or blatant malicious patterns were found. However, interaction with external LLMs and their data handling policies should be considered for privacy.
