Email Summarizer

This project is designed to summarize emails using a custom IMAP client to connect to the user's email inbox and retrieve relevant messages based on specified criteria.

Features

• Connects to an IMAP server to fetch emails.
• Can filter emails by:
  • Subject
  • Date range
  • Sender email address
  • Mailbox (default is 'INBOX')

Debug

• Stdio: If you run this server in STDIO mode, all logs are saved in server.log file, in the location where you run the command. You can change this, setting the DEBUG_LOG_FILE environment variable to a custom path (absolute path).
• Docker: this mode use STDIO mode, so all logs are saved in server.log file, in the location where you run the command. You can change this, setting the DEBUG_LOG_FILE environment variable to a custom path (absolute path).
• Stream: If you run this server in stream mode, all logs are printed to the console.

}

Command (With Docker)

1. Clone the repository git clone <repository-url>
2. Build the Docker image pnpm run docker:build
3. Add the configuration to your app client.

"email-dock": {
  "command": "docker",
  "args": [
    "run",
    "-i",
    "--rm",
    "-e",
    "EMAIL_USERNAME=<your-email>",

    "EMAIL_PASSWORD=<your-app-password>",
    "-e",
    "EMAIL_PORT=993",
    "-e",
    "EMAIL_CLIENT_TYPE=gmail",

    "EMAIL_PROMPT=Summarize the following emails: {{emails}}", 
    "email-summarizer",
  ]
}

Stream HTTP requests

You can also use the HTTP API to interact with the email summarizer. The API expects the following headers:

1. Clone the repository git clone <repository-url>
2. Install dependencies pnpm install
3. Build the MCP pnpm run build
4. Start the MCP pnpm run start
5. Use the MCP serve to http://localhost:5555/mcp

• Send in headers:
  • email-username: Your email address.
  • email-password: Your email app password.
  • email-port: The port for the IMAP server (default is 993).
  • email-client-type: The type of email client (default is 'gmail').
  • email-prompt: Custom prompt for summarization (default is 'Summarize the following emails: {{emails}}'). Must include {{emails}} to insert the email content. As above, you can use a file path or a URL.

Future work

I'll be working on:

• Allow execute action as marking emails as read, deleting, etc.
• Allow override default prompt for the summarization.
• Adding more filters and options for email retrieval.
• Allow fetch whole body information of the email (text, HTML, attachments, etc.).
