📧 Mailing Manager MCP (v1.1.0)

Enterprise-grade Multi-Account Email Orchestration powered by Model Context Protocol

📋 Overview

Mailing Manager MCP is the most advanced, secure, and production-ready Model Context Protocol (MCP) server for email management. Designed for AI agents (Gemini, Claude, GPT), it transforms your mailboxes into a structured, searchable, and intelligent memory bank.

It allows AI assistants like Claude and Cursor to manage multiple email accounts with advanced features while keeping your credentials ultra-secure.

🌟 Killer Features

🔐 Universal Secure Handshake (A+B+C)

Configure any account safely across any environment:

• Method A (Local): Fast setup via local browser.

• Method B (Direct): Quick injection for trusted environments.

• Method C (Public Tunnel): Configures remote clients (n8n, mobile) via secure temporary SSH tunnels (Pinggy).

🧠 FTS5 Local AI Memory

Don't let your AI drown in tokens. Mailing Manager syncs your emails to a Local SQLite Full-Text Search (FTS5) table:

• Instant Search: Sub-millisecond lookups across all accounts.

• Token Optimization: Extracts clean text, removing heavy HTML and technical headers.

• Attachment Awareness: The AI sees what's available to download without fetching binaries.

🔄 Delta Synchronization

Intelligent incremental sync logic that only fetches what's new.

• Performance: Syncs newest first and stops at the last known email.

• Control: Configurable limits (Default 30, Max 100 per session).

• Sync Status: View last synced UID, total count, and date range with get_sync_status.

• Reset Sync: Clear local cache and force full re-sync with reset_sync.

🧵 Thread-Aware Intelligence (v1.1.0)

Smart conversation threading for context-rich AI replies:

• Thread Detection: Auto-detects conversations via Message-ID, In-Reply-To, and References headers.

• Thread Fetching: get_email_thread retrieves all emails in a conversation chronologically.

• Thread Summary: get_thread_summary generates condensed summaries (key participants, topic, timeline).

• Auto-Context Injection: Reply with thread_aware: true to automatically inject thread history into your reply body.

📜 360° Activity Audit

Full transparency for both the user and the AI. Every action is logged in a dedicated activity journal:

• Read/Sent: Know exactly what was accessed or dispatched.

• Sync/Download: Track background memory updates and file transfers.

• Task/Directive: Monitor automated workflows.
