How to add Proton Mail to Cursor
- Open Cursor Settings → MCP and add a new server, or edit
~/.cursor/mcp.json(or.cursor/mcp.jsonin a project). - Paste the remote URL, or the install config from the server page for a local server.
- Sign in if the server asks, then use it in Agent chat.
Menus change, so check Cursor's MCP docs. Every server page has a copy-paste config for Cursor.
Is it safe to connect Proton Mail to Cursor?
Check the publisher and trust grade first. Proton Mail doesn't run an official MCP server we can verify, so every server here comes from a third party and can see whatever your account can.
