Proton MCP Server について

29 MCP tools across reads (mail_list, mail_search, mail_read, labels_list, …) and writes (mail_send, mail_reply, mail_move, labels_create, mail_draft_*, …). Every write tool is gated by a YAML policy engine + Touch ID approval; every tool call writes a redacted row to a local aud

概要

What is Proton Mcp?

Proton Mcp is a signed, notarized, Touch-ID-gated bridge between Proton Mail and Claude, running entirely on your Mac. It provides 31 MCP tools that let Claude read, search, organize, draft, and send your mail, with every outgoing message requiring a Touch ID prompt showing the literal recipients.

How to use Proton Mcp?

Install via Homebrew: brew tap just-an-oldsalt/proto-mcp && brew install --cask proto-mcp. Then run protonmcp login (Proton SRP password + 2FA + key unlock), protonmcp backfill (pull message envelopes into local mirror), protonmcp daemon install (register and start the background daemon), and protonmcp install (connect to Claude Desktop + Claude Code). Restart Claude to see the tools under protonmcp in /mcp.

Key features of Proton Mcp

31 MCP tools for read, search, organize, draft, send, and attachments.
Every send re-prompts with Touch ID showing literal recipients and subject.
Default-deny: unknown tools don’t run; write tools require explicit policy.
Signed, notarized, hardened-runtime binary with startup integrity check.
Local SQLite mirror for fast, offline-capable reading.
Per-tool YAML configuration (rate limits, allowed recipients, idle lock timer).

Use cases of Proton Mcp

Ask Claude to summarize your Proton Mail inbox.
Have Claude organize newsletters into folders and mark them read.
Claude drafts and sends replies after Touch ID approval.
Search and read threads offline using the local mirror.
Automate mail filing and labeling while keeping human approval on sends.

よくある質問

What dependencies does Proton Mcp require?

macOS 13+ is required for the prebuilt signed/notarized binary. Source builds need Go 1.26.4+ and Xcode Command Line Tools (for `swiftc`). Linux builds compile but the authentication flow won’t work.

How does Proton Mcp protect my data?

Every send re-prompts via Touch ID showing literal recipients. The daemon listens on a `0600` Unix socket, never a network port. In-memory session is zeroed on screen lock, sleep, or an idle timer. An honest, redacted audit log scrubs secrets but keeps recipients literal.

Where are my mail contents stored?
