A tool parameter here reaches a dangerous call
That is not a flaw by itself — but it is where things go wrong when it is not the job. We re-read this code on every release. Watch it and you hear from us the day another one appears.

The author’s registry entry marks them as required.
Optional settings from the registry entry, left out of the block above:
EMAIL_IMAP_PROVIDER (Provider — icloud, gmail, yahoo, outlook, or custom (auto-detected from email domain if unset)), EMAIL_IMAP_IMAP_HOST (Custom IMAP host (for provider=custom)), EMAIL_IMAP_SMTP_HOST (Custom SMTP host (for provider=custom)), EMAIL_IMAP_IMAP_PORT (Custom IMAP port), EMAIL_IMAP_SMTP_PORT (Custom SMTP port), EMAIL_IMAP_MAX_RECIPIENTS (Safety cap: maximum combined To+CC+BCC recipients per email_send call. Defaults to 25; raising bypasses spam-prevention guardrails against prompt-injection-driven mass sends), EMAIL_IMAP_RATE_LIMIT_PER_HOUR (Safety cap: maximum email_send calls per rolling window. Defaults to 50; protects against runaway sends when injection content escapes the LLM's intent), EMAIL_IMAP_RATE_LIMIT_WINDOW_MS (Sliding-window length for the rate limit (ms)), MCP_WORKSPACE_PATH (Workspace directory that email_get_attachment downloads into (fresh email-imap-attachment-* staging directories). Defaults to the system temp directory).
