Proton Mail Mcp

Overview

Proton Mail Mcp is a Model Context Protocol (MCP) server: Proton Mail MCP via Bridge (IMAP/SMTP) · 13 tools · dual transport stdio + HTTP. Because it speaks the Model Context Protocol, AI assistants can use Proton Mail Mcp as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the npm package @alexendros/proton-mail-mcp speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need PROTON_USERNAME, PROTON_PASSWORD. The current release is v0.1.2, published under the AGPL-3.0 license, with source at Alexendros/proton-mail-mcp on GitHub.

On mcp.site, Proton Mail Mcp sits in the AI & Agents category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
