Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
제작자가 쓴 설명(영어 원문)
Read-only MCP server for your mail — provider-agnostic IMAP that never marks a message as read.
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.

A read-only MCP server for reading your mail. Provider-agnostic: it speaks IMAP, so it works with Outlook.com, Gmail, Fastmail, iCloud, or a self-hosted server — the provider is a line of config, not a code change.
Read-only by construction. Folders are opened with EXAMINE, never SELECT, and bodies are fetched with BODY.PEEK, so reading a message does not even mark it as read. There are no send, move, delete, or flag code paths, and a test asserts none are ever added.
📖 Full documentation: [https://bgalmes.github.io/rubit-mcp-mail/](https://bgalmes.github.io/rubit-mcp-mail/)
Download the installer for your system from the latest release and run it:
| System | File |
|---|---|
| Windows | rubit-mcp-mail-setup-windows.exe |
| Linux | rubit-mcp-mail-setup-linux — chmod +x it first |
Nothing needs to be installed beforehand: Python and every dependency are inside that one file. A window asks for your provider and email address, signs you in, and registers the mail server with Claude Desktop and Claude Code if it finds them — restart Claude Desktop afterwards and your mail is there. It also leaves you a rubit-mcp-mail Settings shortcut for everything you want to change later. No terminal, at any point.
There is no macOS installer; on a Mac, install from source (below).
A note on antivirus warnings. Windows Defender or Avast may flag this .exe. This is a known false positive common to unsigned PyInstaller-built applications, not anything this project's code does — see the install guide for what to do about it. Every published SHA-256 is listed on the changelog.
| Tool | What it does |
|---|---|
list_accounts | Configured accounts and whether each is authenticated |
list_folders | Folders with normalized roles and unread counts |
list_messages | Browse a folder, newest first, paginated |
search_messages | Server-side search by text, sender, subject, date range, unread |
read_message | Full headers, body text, attachment metadata |
get_attachment | Save one attachment into the download directory |
Folders are addressed by role — inbox, sent, drafts, junk, trash, archive — so you never need to know that Outlook calls it Junk Email while Gmail calls it [Gmail]/Spam. Raw folder names work too.
Full arguments and return shapes: Tools reference.
If you already have Python 3.11+ and would rather not run an installer:
pip install rubit-mcp-mail
rubit-mcp-mail install # the same setup wizard, from the terminal
cd /path/to/rubit-mcp-mail
conda create -p ./.venv python=3.12 pip -y # this machine has no python3-venv ./.venv/bin/python -m pip install -e .
Then configure an account, rubit-mcp-mail auth , and rubit-mcp-mail doctor. The Windows variant and the full walkthrough are in Install from source.
Microsoft has retired basic auth for Outlook.com, so Outlook needs a free Azure app registration — seven steps, done once, written out in Setting up Outlook. Everything else takes an app password:
[accounts.personal]
provider = "generic" email = "you@fastmail.com" host = "imap.fastmail.com"
Known hosts: Gmail imap.gmail.com, Fastmail imap.fastmail.com, iCloud imap.mail.me.com, Yahoo imap.mail.yahoo.com. Gmail and iCloud require an app-specific password, not your login password.
If your Microsoft account genuinely can't register one, you can use the public client ID that other open-source mail tools already share for this purpose — Thunderbird's, 9e5f94bc-e8a4-4e73-b8be-63364c29d753. Paste it in as client_id. The consent screen will say "Thunderbird", and because the ID is outside our control Microsoft could rotate it. Details and caveats: Can't register your own app?.
Any account-scoped tool can be forbidden for a given account with disabled_tools in config.toml, or by unticking a box on the settings window's Permissions tab. A blocked call returns a plain Error: ... string to the model rather than failing silently. See Permissions.
claude mcp add rubit-mail --scope user -- "$(pwd)/.venv/bin/rubit-mcp-mail" serve
Claude Desktop needs a JSON entry instead, and on Linux it needs the session environment passed explicitly or the keyring is unreachable — Register with Claude has both, and Troubleshooting has the logs.
skills/rubit-mail/SKILL.md tells an agent when to reach for the mail tools and how to chain them, and reminds it that the server is read-only and that mail content is untrusted. For Claude Code, copy it into your user (or a project's .claude/) skills directory:
mkdir -p ~/.claude/skills && cp -r skills/rubit-mail ~/.claude/skills/
Any other agent that reads SKILL.md files works the same way. See Agent skill.

Those are the same checks CI runs. Commit messages follow Conventional Commits and drive automatic versioning — see CONTRIBUTING.md and AGENTS.md. Building the installers and adding a provider are covered in Contributing.

Every merge to main prepares a release PR carrying only the pyproject.toml and CHANGELOG.md diff; a maintainer merges it by hand, which publishes the prerelease and builds the installers; promote-release.yml is dispatched manually to drop the -rc.N suffix. The human merge is load-bearing — GitHub raises no events for anything GITHUB_TOKEN does. Full flow: CONTRIBUTING.md and How releases work.
IMAP search is substring-based, bodies are truncated at 20,000 characters, only text parts are downloaded, and Microsoft is actively tightening third-party mail access. The details are in Notes and limits.
