protonmail-mcp: give an agent email access without a blank check

An email is untrusted input

Asking an agent to summarize your messages is useful. But other people wrote those messages. A sender can place instructions in one, telling the agent to send data elsewhere, delete a message, or ignore the original request. Giving the agent unrestricted mailbox access can turn a reading task into a risk of unintended action.

I built protonmail-mcp around this boundary. The server connects an MCP client to Proton Mail through Proton Bridge, which exposes IMAP and SMTP locally. It offers specific tools to the agent instead of allowing arbitrary IMAP or SMTP commands.

Introduction

Manually juggling SSH keys across different projects and hosts is both tedious and error‑prone. I built ssh-keybuild to provide a lightweight, reliable, all-in-one solution to:

Quickly generate ed25519 or RSA keys
Auto‑add the key to your SSH agent
Copy the public key to your clipboard
Update ~/.ssh/config without duplicates

In this post, we’ll explore the script’s main features and how to get up and running in minutes.
