Proton Safe MCP server

Let your AI read, search and draft Proton Mail emails, with no ability to send anything.

This is a small helper program that connects your AI assistant to your Proton Mail account, through the official Proton Mail Bridge on your own computer. It lets the AI look through your mailbox, open messages, peek inside PDF and CSV attachments, and prepare draft emails for you. It is handy if you want help dealing with a busy inbox but you still want the final say on what actually goes out.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. An MCP server is a small helper program that gives it a new skill or a connection to another app. This one gives your AI a connection to your Proton Mail account, so it can search and read your messages and prepare drafts when you ask. It does that by talking to Proton Mail Bridge, a free official Proton tool that runs on your own machine.

What this MCP server does

You ask your AI something about your mailbox, like find emails from a client last week. The AI passes that request to this helper program, which talks to Proton Mail Bridge on your computer. Bridge fetches the matching messages from your Proton account, and the helper sends the results back to the AI. Your AI then shows you a summary or the text in the chat. If you want a reply, it can prepare a draft in Proton Mail for you to review and send yourself.

What you can do with it

Search your inbox for messages by keyword or sender
Read a specific email and summarise it for you
List your folders and show how many messages are in your inbox
Extract the text inside PDF, TXT and CSV attachments so the AI can read it
Suggest reply recipients and a subject line for a reply
Prepare a draft email, with attachments, ready for you to review
Check that your Bridge connection is working

Try asking your AI

“Search my inbox for anything from my accountant in the last month and summarise it”
“Read the latest email from the supplier and tell me what they are asking for”
“Open the PDF attached to the invoice email and list the line items”
“Draft a short reply to Sara confirming the meeting on Thursday, then I will review it”

What it gives back to you

You get plain answers in the chat: lists of matching emails with their subject, sender and date, or a summary of a message you asked about. When you ask it to open an attachment, it gives back the extracted text, not the file itself. For drafts, it tells you what it prepared and where to find it. Nothing is sent, moved or deleted, so the chat is mostly information and drafts waiting for your review.

Before you start

What you need

A Proton plan that supports Proton Mail Bridge
Proton Mail Bridge installed, signed in and running on the same computer (Linux for the released version)
A working keyring on your computer, such as gnome-keyring, to store the Bridge password
Python 3.11 or newer and the uv tool if you install it from the command line

Good to know

It can create drafts in your mailbox, so check the recipients and text before you press Send in Proton Mail; it cannot send, delete or move anything by itself.
