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

Quick version: LMCP is a Mac app that turns the apps you already use into tools your AI can call. Install it once and Claude Desktop, Claude Code, Cursor, Codex and other MCP clients can work with Mail, Calendar, Teams, Slack, WhatsApp, iMessage, Outlook, OneDrive, Google Drive, Zoom, Office files, your browser and your terminal. That's 190+ tools, and most of them work without connecting a single account.

Why we built it

If you've wired MCP servers by hand, you know the drill. One server per app, an API key here, an OAuth app registration there, and for anything Microsoft, a trip to your IT admin for consent. Meanwhile all that data is already sitting on your machine, inside apps you're logged into.

So we built one install that reaches what's already there.

How it works, briefly

The MCP server runs on your Mac and the tools execute there. Where it can, LMCP uses what the apps already keep locally instead of going through cloud APIs. Teams is the fun example: instead of Microsoft Graph, we read the local cache the Teams app keeps on disk, so there's no Azure app to register and no admin consent to chase.

The installer finds the AI apps you have and configures them for you. If you use Claude Code, it's just there the next time you start a session.

What people actually do with it

A few things that work well from Claude Code or Codex:

• "Open our analytics dashboard, grab this week's numbers and put them in a spreadsheet." The browser tools use your existing logged-in sessions, so no credentials to hand over.
• "Summarize what happened in the #launch Slack channel since Monday."
• "Find last week's invoice PDF in my Downloads and pull the totals into an Excel file."
• "What's on my calendar tomorrow, and is there anything in my inbox I should read before those meetings?"

The fun part is chaining. Once your agent can read mail, check your calendar and drive the browser, small workflows you'd never bother scripting become one prompt.

Turning it into automations

Where it gets interesting is when you stop typing the prompt every time.

LMCP has recipes: you save a multi-step workflow once ("every morning, pull new orders from the dashboard, add them to the sheet, flag anything unusual") and run it again whenever you want. And since Claude Code and Codex can run without you sitting there, you can hook those workflows into a script or a scheduled job. Your Mac does the clicking, the agent does the thinking.

Some of the heaviest setups we've seen look less like "a person chatting with Claude" and more like small pipelines running on their own: scraping a few sites, checking a couple of inboxes, writing the results somewhere useful.

What it doesn't do

Worth being upfront about this:

• Tools run on your Mac, but your AI provider still sees whatever you ask it to read. LMCP doesn't make Claude or ChatGPT local.
• It doesn't bypass app permissions or company policies.
• Web AIs like claude.ai or ChatGPT can use it through an optional cloud connector, which is off by default. Desktop and CLI clients don't need it.

Try it

It's free. If you're comfortable with a shell:

curl -fsSL 'https://local-mcp.com/install?ref=devto-g1' | bash

Or npx -y local-mcp@latest setup, or the signed installer at local-mcp.com. Restart your AI client afterwards, since MCP tools load at startup.
