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.

Download Local MCP for Claude Desktop

macOS · Windows · Linux — ~16 KB bootstrap, native runtime downloads on first launch

How to install

1Click the download button above. Your browser saves a file named local-mcp.mcpb.
2Double-click the file. Claude Desktop opens with an install dialog.
3Click Install. The extension appears in Settings → Extensions and Claude can immediately call any of the 75+ tools.
4The first time Claude calls a tool that needs it, your OS will ask permission (Calendar, Contacts, Mail… on macOS; UAC prompts on Windows). That's normal — Local MCP runs entirely on your machine.

Troubleshooting

“This extension is unsigned” warning: Click Install Anyway. We're rolling out code signing in an upcoming release; the bundle behaviour is identical.
Double-click does nothing: Make sure Claude Desktop is installed and has been opened at least once. Then drag the .mcpb file onto the Claude Desktop window.
Download button fails or MCPB registry is down: The installer file is served directly from LMCP — you do not need the public MCPB registry. Retry download or use the full macOS / Windows installer.
I want auto-update, the menu bar Tray, or to use Local MCP from Cursor / ChatGPT: Use the full installer instead — it includes the Tray app, LaunchAgent, auto-updates and the cloud connector. Download the macOS installer.

Other install methods

macOS .pkg / Windows .exe — recommended if you also use Cursor, ChatGPT or want auto-update. Download.
