A lightweight [MCP](https://modelcontextprotocol.io) server that gives AI agents
read access to a Proton Mail mailbox through a local
[Proton Bridge](https://proton.me/mail/bridge) instance.

Proton does not provide a public API for reading your mailbox. Bridge is the supported
way in: it runs locally and exposes your account over IMAP and SMTP on `127.0.0.1`.
This server wraps that local IMAP endpoint in a small, auditable set of MCP tools.

## Scope

Capabilities are opt-in through policy (see [Capability policy](#capability-policy)) and
enforced server-side:

- **read** (default): folders, messages, search, threads, digests, attachments and `.eml`
  export into a local sandbox. Mailboxes are opened with IMAP `SELECT ... READONLY`;
  nothing is modified, not even the `\Seen` flag.
- **draft**: create, preview, reply/forward, update and delete drafts, all two-phase.
- **organize**: seen/flagged state, moves with undo, label add/remove.
- **send**: submit an existing draft through Bridge SMTP after allowlist, quota, size
  and loop-guard checks.
- **delete**: permanently erase one message from Trash, with a typed confirmation phrase
  and no bulk operation.

Every mutation is prepare/commit with payload-bound confirmation tokens; see
[SECURITY.md](SECURITY.md) for the security model.
