Mailwarden MCP

A native Gmail MCP server providing full mailbox triage for AI assistants. It features mailbox-side snooze using dated labels, trusted search with live label verification, sender authentication via SPF/DKIM/DMARC headers, and scalable bulk operations. It prioritizes security by excluding send tools by default and offering structured outputs.
