Proton Safe MCP
Draft-only Proton Mail MCP server built on Proton Mail Bridge. It can read and search mail, create drafts with attachments, and requires out-of-band human approval in a local terminal before draft creation; it deliberately cannot send email. Public GitHub repository created August 29, 2026.
