Overview Installation

Overview

Proton Safe MCP is a Model Context Protocol server that lets you read and search your Proton Mail inbox, then compose human-approved draft emails without any send capability. It integrates directly with AI assistants like Claude, exposing email operations as tools the model can invoke securely on your behalf.

The server runs locally on your machine as a Python package. Install it via uvx proton-safe-mcp, and it communicates with your AI client over stdio. You'll need to set the PROTON_BRIDGE_USER environment variable to connect to Proton Mail. The latest release is v1.0.2, published under the MIT license with full source code available at fbossiere/proton-safe-mcp on GitHub.

Proton Safe MCP belongs in the Communication category and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain this project, you can claim this listing to verify ownership and keep the information up to date.
