Proton Mail MCP server

This is a small helper that connects your AI assistant to your Proton Mail account. Once it is set up, you can ask your AI to read, search, send, reply to, and tidy up your email in plain language. It is handy if you use Proton Mail and want to save time on everyday inbox chores.

What this MCP server does

You ask your AI something about your email, like find a message or send a reply. The AI passes your request to this helper program running on your computer. The helper talks to Proton Mail through Proton Mail Bridge and your SMTP login. Then it brings the answer back into your chat, or makes the change you asked for, like moving a message or sending a reply.

Try asking your AI

• “Show me the five most recent unread emails in my inbox”
• “Find every email from my landlord in the last three months”
• “Reply to the last message from Anna and say I will send the file tomorrow”
• “Move all newsletters from this week into the Newsletters folder”

What it gives back to you

You get answers in plain chat: lists of messages with sender, subject and date, short previews, counts, and folder summaries. When it sends or changes something, it tells you what it did, like the Message-ID of a sent email or a note that a message was moved to Trash. For bulk actions you can ask for a preview first, so you see what would happen before anything changes.
