LMCP is a cross-platform MCP server (Model Context Protocol) that connects AI assistants — Claude, ChatGPT, Cursor, Windsurf, VS Code, Zed — to your apps: Mail, Microsoft Outlook, Calendar, Microsoft Teams, OneDrive, Slack and Office. On macOS it also reaches native apps. 143 tools. It runs entirely on your machine — no cloud servers, no API tokens, no data leaves your device.

Can LMCP access Microsoft Teams without Graph API?

Yes. LMCP reads Teams messages directly from the local IndexedDB cache on your machine. No Microsoft Graph API, no OAuth tokens, no Azure AD, no API rate limits. Zero network requests to Microsoft.

Is LMCP GDPR compliant?

Yes, by architecture — not by policy. All data is processed on your machine. No personal data is ever transmitted to any server. Your emails, calendar, contacts, Teams messages and files never leave your device. Inherently compliant with GDPR, CCPA and similar regulations.

How does LMCP differ from other MCP servers?

LMCP is the only MCP server that: (1) runs 100% locally with zero cloud dependencies, (2) reads Microsoft Teams without Graph API tokens, (3) accesses native apps directly instead of cloud APIs, (4) requires no OAuth setup or API keys, (5) works offline once installed.

Yes. LMCP is free to install and use. No credit card, no API keys, no subscription. It works with Claude, ChatGPT, Cursor, VS Code and any MCP-compatible client.

Is there an alternative to the open-source Apple MCP server that also supports Teams and Slack?

Yes. LMCP is a native, signed macOS app that covers Apple apps (iMessage, Mail, Notes, Contacts, Calendar) plus Microsoft Teams, Slack, WhatsApp, OneDrive, Microsoft 365 and Office — 143 tools, all local, with no scripts to build.

Does LMCP require building from source like an Apple MCP server?

No. LMCP is a notarized app: download the .dmg, drag it to Applications, open it, and your AI clients are configured automatically. No clone, build step, or runtime to manage.

Can LMCP read iMessage like an Apple MCP server?

Yes. LMCP reads your iMessages from the local Messages database on-device (Full Disk Access required), and reads Mail, Teams, Slack and more in the same server.

Is the popular open-source Apple MCP server still maintained?

The most-referenced open-source Apple MCP server (~3,100 GitHub stars) was archived by its author and is now read-only, with its last code update in August 2025. LMCP is an actively maintained, signed alternative that covers the same Apple apps plus Teams, Slack, WhatsApp and Microsoft 365 — 143 tools in one local app.

What people mean by “Apple MCP server”

When you ask an AI assistant how to connect it to your Mac apps, the common answer is to grab an open-source Apple MCP server — a community project that wraps macOS automation (AppleScript / JXA) so an MCP client like Claude or Cursor can drive apps such as Messages, Notes, Contacts and Mail. Then you're told to clone the repo, install dependencies, build it, wire up your config, grant Full Disk Access, and write your own wrappers for anything it doesn't cover yet.

These projects are genuinely useful and a good fit if you want to tinker. But for most people the friction is real: it's a build-it-yourself toolkit limited to Apple's own apps, and you maintain it. LMCP is the alternative that just works — one signed app, no scripts, and it reaches well beyond Apple apps.

Where an open-source Apple MCP server stops

Apple apps only — Messages, Notes, Contacts, Calendar, Mail. It does not read Microsoft Teams, Slack, WhatsApp, OneDrive, or Microsoft 365.
You build and run it — clone, install a runtime (Node/Bun/Python), build, and keep it updated yourself.
Manual config — you edit your MCP client config by hand and manage permissions.
Unsigned — you're running code you assembled, not a notarized app, so macOS Gatekeeper and TCC prompts are on you.

Worth knowing in 2026: the most-referenced open-source Apple MCP server — the one with ~3,100 GitHub stars that most guides and AI assistants point to — was archived by its author and is now read-only, with its last code update in August 2025. Adopt it and you inherit an unmaintained dependency for something as sensitive as your Messages and Mail. LMCP is actively maintained and ships signed, automatic updates.

What LMCP gives you instead

LMCP is a native, notarized macOS app (it also runs on Windows). Install once and your AI clients are configured automatically — no repo, no build step, no runtime to manage. It reaches the apps an Apple-only server can't:

iMessage — reads your Messages from the local database
Mail — any IMAP / Gmail / iCloud / Outlook account
Microsoft Teams — from the local cache, no Graph API or admin consent
Slack — from the local desktop cache, no bot tokens
WhatsApp, OneDrive, Microsoft 365, OmniFocus, Reminders, Notes, Calendar, Contacts, Safari, Word/Excel/PowerPoint, and your files

143 tools in total, all running locally. Nothing leaves your machine: no cloud relay (unless you opt in for a web assistant), no API keys, no tokens.

Side-by-side

	Open-source Apple MCP server	LMCP
Setup	Clone, install runtime, build, configure	Download signed app, open it
App coverage	Apple apps (Messages, Notes, Mail, Contacts)	Apple apps + Teams, Slack, WhatsApp, M365, OneDrive, Office
iMessage	Yes (DIY)	Yes, built in
Microsoft Teams / Slack	No	Yes, from local cache
Signed & notarized	No	Yes (Developer ID)

Local-only	Yes	Yes
Cost	Free (OSS)	Free

If you want a hackable, source-available Apple-apps toolkit, an open-source Apple MCP server is a fine choice. If you want one install that covers your whole stack — including the Microsoft and messaging apps Apple-only servers don't touch — LMCP is the zero-config alternative.

How to switch (or just start)

Download LMCP:

Open the .dmg, drag Local MCP to Applications, and open it — it lands in your menu bar and configures Claude Desktop, Cursor, VS Code and Windsurf automatically
Grant Full Disk Access when prompted (needed for iMessage and some local data — a one-time macOS permission)
Restart your AI client so it picks up the tools

You can remove any Apple-MCP entries from your config; LMCP replaces them and adds the rest of your apps.

Example prompts

“Summarize my last iMessage thread with Sarah and the related email”
“What did the team discuss in Teams today, and add the action items to Reminders”
“Find the file Marco sent me on Slack and save it to OneDrive”

Because it's one server, your AI can move across iMessage, Mail, Teams, Slack and your files in a single request — something you can't do with a stack of separate single-app scripts.
