MCP Email Server

A Dockerized, OpenAPI-based MCP email assistant for law firms and legal teams.

Integrates:

• IMAP/SMTP email operations
• Shared/public folder support
• New-message tracking and flagging
• Conflict check search
• CalDAV/CardDAV (e.g., Nextcloud) for calendar and contacts
• Triage guidance using personnel/chain-of-command

Designed to be consumed by LLMs via OpenAPI tool servers (e.g., Open WebUI).
