Unofficial self-hosted MCP connector for Proton Mail Bridge and SimpleLogin.
이 세 가지는 절대 하나의 점수로 합치지 않아요. 의견, 측정, 인기는 서로 다른 것이니까요.
이 서버는 아직 쉬운 말로 된 요약을 쓰지 못했어요. 아래는 레지스트리에서 읽어 온 사실이에요.
쓰고 있는 AI 앱을 고른 다음 설정을 복사하세요.
PROTON_BRIDGE_USERNAME, PROTON_BRIDGE_PASSWORD, PROTON_BRIDGE_EMAIL, SIMPLELOGIN_API_KEY비밀로 표시된 값은 내 계정의 열쇠예요. 절대 다른 사람과 공유하거나 채팅에 붙여 넣지 마세요.

Proton Workflow Connector (PWC) is a self-hosted MCP connector for reading, sending, organizing, and automating Proton Mail through Proton Mail Bridge. It works with any MCP client or local agent runtime that can launch a stdio server or call a Streamable HTTP MCP endpoint. SimpleLogin support is optional.
This is an unofficial project. It is not affiliated with, endorsed by, or sponsored by Proton AG. The connector uses Bridge-generated IMAP/SMTP credentials. It does not accept Proton account passwords or store Proton login sessions.

Use one local server for the mail work agents usually have to piece together:
dry_run, sanitize outbound HTML by default, bound bulk operations, and allow only configured sender addresses.The server exposes 68 tools in total. See the complete tool reference.
PWC is an MCP server. Your client starts it over stdio or connects to it over Streamable HTTP.
The connector talks to Proton Mail Bridge over local IMAP/SMTP. Bridge must be installed, signed in, and running on the same machine as the connector. One connector process serves one Bridge account.
SimpleLogin is optional. If SIMPLELOGIN_API_KEY is set, PWC adds alias, contact, mailbox, and new-alias polling tools. If it is unset, the Proton Mail tools still work.
For automation, run proton-workflow-watch or call the polling tools from your MCP client. Watcher output can go to a webhook, a JSONL file, or a command.
git clone https://github.com/NtrpyDev/proton-workflow-connector.git
cd proton-workflow-connector python -m venv .venv source .venv/bin/activate python -m pip install .
On Windows PowerShell, activate the environment with .venv\Scripts\Activate.ps1.
Keep the environment file outside the repository:
mkdir -p ~/.config/proton-workflow-connector
cp .env.example ~/.config/proton-workflow-connector/env chmod 600 ~/.config/proton-workflow-connector/env
Edit the copied file with the connection details shown in Proton Mail Bridge. Set PROTON_BRIDGE_EMAIL to the default sender and list every permitted sender address in PROTON_BRIDGE_SENDER_ADDRESSES.
proton-workflow-connector --transport stdio \
--env-file ~/.config/proton-workflow-connector/env
Any MCP client or local agent runtime can use PWC as long as it supports stdio or Streamable HTTP:
proton-workflow-connector --transport stdio --env-file ...--transport streamable-http and point the client at /mcpClaude Code stdio example:
claude mcp add --transport stdio --scope user proton-workflow \
-- "$PWD/.venv/bin/proton-workflow-connector" --transport stdio \ --env-file ~/.config/proton-workflow-connector/env
Codex stdio example:
[mcp_servers.proton_workflow]
command = "/absolute/path/to/repo/.venv/bin/proton-workflow-connector" args = [ "--transport", "stdio", "--env-file", "/absolute/path/to/private/proton-workflow-connector-env" ] default_tools_approval_mode = "prompt" startup_timeout_sec = 20 tool_timeout_sec = 120
Run server_status after connecting. It checks IMAP, SMTP, SimpleLogin, OAuth configuration, and the server version without returning secrets. Then run list_folders; Bridge folder names vary by account and version.
See MCP client setup for generic client configuration, localhost HTTP, hosted Streamable HTTP, Codex, Claude Code, and the plugin wrapper.
Once connected, ask your MCP client to:
billing@vendor.example using the invoices cursor."The connector returns structured data to the MCP client. The client decides how to present it and when to request approval for actions.
| Area | Included operations |
|---|---|
| Search and reading | Search one folder or all selectable folders, read messages and threads, inspect headers, and download attachments |
| Sending and drafts | Send, reply, reply-all, forward, create and update drafts, use allowed alternate senders, and attach files |
| Organization | Create and manage folders, apply Proton labels, change flags, archive, move, copy, restore, and manage Spam or Trash |
| Bounded bulk actions | Preview, mark, star, move, copy, archive, trash, restore, or permanently delete explicit UID lists |
| Automations | Poll persistent cursors or push new-message and new-alias events to a webhook, JSONL file, or command |
| SimpleLogin | Inspect account data and manage aliases, contacts, and mailboxes with an optional API key |
| Deployment | Local stdio, localhost Streamable HTTP, or OAuth/OIDC-protected hosted HTTP |
Proton Contacts are not included because Proton Mail Bridge does not expose them.
The background watcher polls for new mail or newly created SimpleLogin aliases and emits one event per new item:
proton-workflow-watch \
--env-file ~/.config/proton-workflow-connector/env \ --folder INBOX \ --webhook-url https://example.com/hooks/proton \ --interval 60
Key behavior:
UIDVALIDITY changes.--dry-run shows which events and rule actions would fire without delivering, acting, or advancing cursors.Read Triggers and webhooks for event schemas, filters, delivery guarantees, signature verification, rules, and systemd examples.
This connector processes private mail. Its defaults and boundaries are intentionally explicit:
confirm=true after explicit user intent.dry_run=true previews.content_trust: "untrusted", and outbound HTML is sanitized unless trusted_html=true.PROTON_BRIDGE_EMAIL or an address in PROTON_BRIDGE_SENDER_ADDRESSES.Read SECURITY.md before using real mail and Hosted HTTP setup before exposing the connector beyond localhost.
