Connects Claude to Proton Mail via the local Bridge client, exposing 13 tools over IMAP and SMTP. You get read ops (list folders, search with filters, fetch full messages and attachments up to 50MB), writes (send with threading headers, move, flag, delete), and folder management. Runs dual transport: stdio for local CLI work, HTTP with bearer auth and rate limiting for remote clients like Routines. The crypto boundary stays at Bridge on your machine, so end-to-end encryption holds and nothing leaks plaintext to third parties. Ships with connection pooling, retry logic, and a full CI suite. Reach for this when you need Claude to manage a privacy-focused inbox without OAuth handoffs to SaaS providers.
