Let your AI actually use your Mac. Ask ChatGPT, Claude or Cursor to read & reply to your email, manage your calendar, text over iMessage, find your files, and pull data from PDFs — it just does it. It even reaches iMessage and your local apps that the web AIs can't. Tools run on-device — for desktop AIs nothing leaves your Mac; an optional, opt-in encrypted relay lets web AIs reach it. No API keys, free.
Installs in 2 minutes. Auto-configures Claude Desktop, Claude Code, Cursor, Windsurf, VS Code, and Zed. Free — no paid tier yet.

Auto-detects and configures: Claude Desktop · Claude Code · Cursor · Windsurf · VS Code · Zed
Restart your AI client once. That's it.
Prefer not to use the terminal?
You don't need the command line. Get the Mac app from local-mcp.com, drag it to Applications, and open it. The menu-bar app walks you through connecting Claude Desktop, ChatGPT, Claude.ai, or Grok — no setup files to edit. (The terminal install above also auto-configures Claude Desktop, Cursor, VS Code, and more.)
Requirements: macOS 13+ (Ventura or later, Apple Silicon or Intel). Windows & Linux are on the waitlist at local-mcp.com.
Use with ChatGPT (web)
ChatGPT can call your Mac apps through LMCP's Cloud Relay. The full walkthrough with
screenshots is at local-mcp.com/guides/chatgpt-mac —
the short version:
Install LMCP (above) and open the menu bar app → Settings → Connect. Enter your
email, click Connect, then toggle Cloud Data Forwarding ON.
On chatgpt.com (web only — Plus/Pro/Business/Enterprise/Edu):
Settings → Apps & Connectors → Advanced settings → enable Developer mode.
On the Authorize ChatGPT page, paste your token (Settings → Connect → Copy next to
Token) and click Authorize. The token is your secure per-machine credential — no email step.
New chat → + → More → LMCP, then ask "Summarize my unread emails."
Using Claude Desktop, Cursor, VS Code, Windsurf, or Zed? Skip all of this — curl … | bash
auto-configures them locally and nothing leaves your Mac.

Why native?
Most MCP servers call cloud APIs. LMCP talks directly to macOS frameworks:
EventKit for Calendar — reads all providers (iCloud, Google, Exchange)
AppleScript/JXA for Mail — works with any IMAP account
LevelDB for Teams — reads the local IndexedDB cache, no Graph API needed
CNContactStore for Contacts — native framework, no app launch required
File system for OneDrive, Word, Excel, PowerPoint
This means: no API keys, no OAuth, no rate limits, works offline, sub-second responses.
Microsoft Teams without Graph API
The most technically interesting part: Teams messages are read directly from the local LevelDB cache at:
No Azure AD registration, no tenant admin approval, no OAuth tokens. Just the messages already cached on your Mac.
Cloud Relay (optional)
Claude.ai and ChatGPT can't reach localhost. Enable Cloud Relay in the menu bar app — a secure WebSocket tunnel routes requests to your local server. Your data is encrypted in transit and never stored.
How LMCP compares
There are several Mac MCP servers — they optimize for different things. An honest read:
LMCP
Apple-native only (e.g. iMCP)
Cloud aggregators (e.g. Composio)
GUI automation (e.g. Macuse)
Apple apps (Mail, Calendar, iMessage…)

Where LMCP is unique: the work & messaging apps most people live in — Microsoft Teams, Slack, WhatsApp, Microsoft 365 — read locally with no API keys, and reachable from web AIs like ChatGPT and Claude.ai. Apple-native-only servers stop at Apple apps; cloud aggregators need OAuth and route your data through their servers.
Full head-to-head with the other Mac-native servers: LMCP vs Macuse vs iMCP — capabilities, pricing and privacy, kept honest and current.
Schedule a meeting end-to-end — find a free slot, message the person on email and WhatsApp with options, and book it when they confirm. (No cloud scheduler reaches a personal WhatsApp; LMCP does.)
Triage across every channel — "Across my Slack, WhatsApp, Teams and email, what did clients ask that I haven't answered?"
Mirror busy time — copy work meetings onto your personal calendar as private Busy blocks.
Anything the agent sends is preview-and-confirm — you approve before it leaves your Mac.
Popular guides
The things people most often want their AI to reach — and the ones cloud connectors can't:
Read your iMessages — the only MCP server that does it (iMessage has no API; LMCP reads the local database on-device)
All data stays on your Mac — nothing is sent to external servers
No API keys, OAuth tokens, or cloud accounts required
Uses standard macOS TCC permissions (the same "Allow access?" prompts any app uses)
Calendar, Contacts, and Reminders access can be revoked anytime in System Settings
GDPR and CCPA compliant by architecture — tool results are produced on your Mac, and our backend never stores your tool inputs or outputs (see SECURITY.md)
Destructive operations always show a preview and require explicit confirmation

Common questions
Does LMCP send my data to the cloud?
No. The tools run on your own machine and read directly from your installed apps. There is no cloud processing and LMCP's servers never store your data. The optional Cloud Relay is an encrypted tunnel that lets a cloud AI (ChatGPT, Claude.ai, Grok) trigger a tool on your machine — the result is produced locally and the backend doesn't persist tool responses.
Can ChatGPT, Claude, or Cursor read my email, calendar, or Teams without API keys or OAuth?
Yes. LMCP exposes them as MCP tools that read your local apps directly — no Microsoft Graph tokens, no Google API keys, no OAuth setup for the data.
How is this different from a cloud automation platform?
Cloud automation platforms route your data through their servers. LMCP runs the tools on your computer and returns results straight to your AI, so nothing transits a third-party cloud. Choose LMCP when privacy and local-first matter; choose a hosted platform when you want cloud-hosted multi-step workflows.
How is it different from a cloud MCP connector or a Graph-API integration?
Those authenticate against vendor cloud APIs (OAuth tokens, tenant-admin consent). LMCP reads the apps already on your machine — Mail, the local Teams/Slack cache, synced OneDrive — with no API keys and no admin approval for the data.
Can it read Microsoft Teams or Slack without the Graph API or admin tokens?
Yes. It reads the Teams and Slack data already cached locally on your machine.
Can my AI read and write local Excel, Word, PowerPoint, or PDF files?
Yes — it reads and creates Office documents and reads PDFs locally, without uploading them anywhere.
Does it work on Windows?
Not yet — LMCP is macOS-only today. Windows & Linux are on the waitlist at local-mcp.com.
How much does it cost?
Free, no paid tier yet — a permanent license, not a 14-day trial, no subscription.
Roadmap
Shipped:
Cloud connectors — ChatGPT, Claude.ai, Grok, Perplexity, and OpenClaw via the encrypted relay
Microsoft Teams — read and send chats and channel messages (no Graph API)
Already works today via the file tools: any local folder is searchable and
readable right now — including your Obsidian vault and your Google Drive
or Dropbox sync folders — with fs_search, fs_read, and the Finder tools.
No dedicated integration needed to read those files.
Have a feature in mind? Run request_feature from any AI client, or open an issue.
This stops all background processes, removes the auto-start LaunchAgent, deletes the app and binaries, and cleans up the MCP entries from Claude Desktop, Cursor, and other AI clients. Your emails, calendar, and other data are never stored by LMCP and remain untouched.
Support
In your AI client: ask Claude to run report_problem or request_feature
