We built a free MCP server that lets Claude Code use the apps on your Mac

LMCP is a Mac app that transforms your existing applications into tools for AI to access. Once installed, Claude Desktop, Claude Code, Cursor, Codex, and other MCP clients can interact with various apps like Mail, Calendar, Teams, Slack, WhatsApp, iMessage, Outlook, OneDrive, Google Drive, Zoom, Office files, your web browser, and terminal.

Over 190 tools are compatible, and many function without requiring any additional account connections. The app simplifies the process of setting up MCP servers by providing a single installation that connects to the tools already running on your machine.

The server operates on your Mac, and the tools execute locally. LMCP leverages the data already stored in your apps, avoiding the need for cloud APIs. For instance, Teams' local cache on your device can be read instead of using Microsoft Graph. Upon installation, LMCP identifies the AI applications you have and configures them accordingly. Claude Code will be ready for use in your next session.

Users have utilized LMCP in various ways, such as opening analytics dashboards, extracting data from browser sessions without needing explicit credentials, summarizing recent Slack conversations, locating invoice PDFs, and checking calendars for upcoming meetings. The platform allows for the creation of reusable workflows, enabling users to automate tasks like daily order processing and email analysis.

However, it's important to note that while LMCP enhances the capabilities of AI tools, it doesn't bypass the security measures or permissions of the underlying applications.
