Setup

1. Clone and install dependencies

git clone https://github.com/ssk-machines/email-mcp-postale.git
cd email-mcp-postale
pip install -r requirements.txt
# or with uv:
uv pip install -r requirements.txt

2. Create configuration

cp config.json.example config.json

Then edit config.json — add an account entry for each mailbox:

{
  "accounts": [
    {
      "name": "My Account",
      "email": "me@example.com",
      "imap_host": "mail.postale.io",
      "imap_port": 993,
      "smtp_host": "mail.postale.io",
      "smtp_port": 465,
      "username": "me@example.com",
      "password": "your-password"
    },
    {
      "name": "Support",
      "email": "support@example.com",
      ...
    }
  ]
}

Tip: On Postale.io, the username is always the full email address.

3. Test

python server.py

If no errors appear, the server is running correctly in stdio mode.

4. Add to Claude Desktop

Open ~/Library/Application Support/Claude/claude_desktop_config.json and add:

With uv:

{
  "mcpServers": {
    "email": {
      "command": "uv",
      "args": [
        "--directory", "/path/to/email-mcp-postale",
        "run", "server.py"
      ]
    }
  }
}

Or with Python directly:

{
  "mcpServers": {
    "email": {
      "command": "python3",
      "args": ["/path/to/email-mcp-postale/server.py"],
      "env": {
        "EMAIL_MCP_CONFIG": "/path/to/email-mcp-postale/config.json"
      }
    }
  }
}

Replace /path/to/email-mcp-postale with the actual path where you cloned the repo.

5. Restart Claude Desktop

After saving the config, fully quit and reopen Claude Desktop. The email connector should appear as active under "Connectors".

Scheduled Tasks (Cowork)

   - 🟡 REPLY NEEDED: Needs a reply, but not time-critical
   - 🟢 FYI: Just read, no action needed
   - ⚪ UNIMPORTANT: Newsletters, marketing, spam
3. Draft a reply for each 🔴 and 🟡 email using save_draft.
4. Mark ⚪ emails as read with mark_as_read.
5. Create a clear summary as a briefing.

Every Friday at 5:00 PM:
1. Search all accounts for newsletter and marketing emails from the past week.
2. Create a list for batch deletion.
3. Show me the list for confirmation before deleting.
