“Find the unread messages from Alice this week, summarize them, and move the finished thread to Archive.”

Why this server?

🔎 Find what matters Search across folders by sender, recipient, subject, body, date, read state, and reply state.	✉️ Act without leaving the conversation Read, send, reply, move, and delete messages using natural language.
📎 Work with attachments Inspect metadata, download files, and send local attachments through explicit filesystem allowlists.	🔐 Keep control Run locally, connect directly to your mail provider, verify TLS certificates, and enforce payload limits.

What can I ask?

Goal	Example prompt
Catch up	“Summarize my unread email from today.”
Find a message	“Find messages from finance@example.com about the Q3 budget.”
Organize the inbox	“Move the completed thread from INBOX to Archive.”
Reply with context	“Reply to the latest message from Alex and keep it in the same thread.”
Handle files	“Save the PDF attachment from that message to my Downloads folder.”
Send polished email	“Send the project update with my text and HTML signature.”

Quick Start

[!IMPORTANT] Enable IMAP and SMTP for your account before starting. This server currently supports password or app-password authentication; OAuth2 is not yet supported.

Prepare your IMAP/SMTP server details and an app password where supported.
Add the server to your MCP client using one of the configurations below.
Restart or reconnect the client, then ask: “Show me unread emails from today.”

Install Node.js 22.13.0 or newer before configuring your MCP client. All examples use npx -y mcp-mail-server, so there is no need to install the server globally.
