MCP Overview

The Model Context Protocol (MCP) enables AI assistants like Claude to directly access and interact with your MoMail data through a standardized interface.

What is MCP?

MCP (Model Context Protocol) is an open standard for connecting AI assistants to data sources. With MoMail’s MCP server, Claude can:

• Search your emails using natural language
• Retrieve specific emails and conversation threads
• List your mailboxes and their contents
• Access email metadata and attachments

Architecture

MoMail implements the MCP protocol using StreamableHTTP transport:

┌─────────────┐      StreamableHTTP       ┌─────────────┐
│   Claude    │  <───────────────────>   │ MoMail MCP  │
│   Desktop   │      (HTTP POST)         │   Server    │
└─────────────┘                           └─────────────┘
                                                 │
                                                 ▼
                                          ┌─────────────┐
                                          │  MoMail     │
                                          │  Database   │
                                          └─────────────┘
