Proton Mail MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Proton Mail MCP?

Proton Mail MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @alexendros/proton-mail-mcp.

Is Proton Mail MCP still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect Proton Mail MCP?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @alexendros/proton-mail-mcp straight from npm; nothing to host, nothing to sign up for.
