概览

What is MCP Email Server?

The MCP Email Server is a Model Context Protocol server that enables LLMs to compose and send emails and search for attachments in specified directories using SMTP.

How to use MCP Email Server?

Install dependencies (pydantic, python-dotenv), create an email.json file with SMTP server configurations, set the SENDER and PASSWORD environment variables, and run the server with python -m mcp_email_server --dir /path/to/attachment/directory. Configure it in Claude.app by adding the server details to the MCP servers settings.

Key features of MCP Email Server

  • Send emails with multiple recipients and attachments
  • Search for files in directories using pattern matching
  • Secure email transmission via SMTP
  • Supports common file types for attachments (documents, archives, text, images)
  • Provides both tools and prompts for email and attachment operations

Use cases of MCP Email Server

  • An LLM assistant sending an email with attachments on behalf of a user
  • Automating email notifications by composing and sending messages from within a conversation
  • Searching a local directory for files that match a pattern before attaching them to an email
  • Integrating email capability into a Claude-based workflow without leaving the chat

常见问题

1

What dependencies are required?

The server requires `pydantic` and `python-dotenv` packages. Install them via pip.

2

How do I configure email credentials?

Set the `SENDER` environment variable to your email address and `PASSWORD` to your SMTP password or app-specific password. For Gmail and similar services, an app‑specific password may be required.

3

What file types are supported for attachments?

The server supports documents (doc, docx, xls, xlsx, ppt, pptx, pdf), archives (zip, rar, 7z, tar, gz), text files (txt, log, csv, json, xml), images (jpg, jpeg, png, gif, bmp), and other files like md.

4

How do I set up the SMTP server?

Create an `email.json` file in the server directory with an array of objects, each containing `domain` (e.g., `@gmail.com`), `server` (e.g., `smtp.gmail.com`), and `port` (typically 587).

5

Are there any security considerations?

You should use an app‑specific password for email accounts that require it. The server also restricts attachment file types to a limited list for security reasons.
