What your AI can do

143 tools total. Read operations run instantly. Write operations (send email, delete event) show a preview and require confirmation.

Install

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

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. Two one-click options:

• Claude Desktop users → download the one-click extension at local-mcp.com/install/mcpb and double-click it. No terminal, no config.
• Everyone else → get the Mac app from local-mcp.com, drag it to Applications, and open it. The menu-bar app walks you through connecting ChatGPT, Claude.ai, or Grok — no setup files to edit.

Requirements: macOS 12+ (Monterey or later, Apple Silicon or Intel). LMCP also runs on Windows (beta — Outlook, Teams, Slack, OneDrive, Office, Microsoft To Do, Explorer) and Linux (cloud / server agents — Microsoft 365, Slack, Google Drive, Office).

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:

1. Install LMCP (above) and open the menu bar app → Settings → Connect. Enter your email, click Connect, then toggle Cloud Data Forwarding ON.
2. On chatgpt.com (web only — Plus/Pro/Business/Enterprise/Edu): Settings → Apps & Connectors → Advanced settings → enable Developer mode.
3. Apps & Connectors → Create: Name LMCP, URL https://www.local-mcp.com/mcp, Authentication OAuth.
4. 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.
5. 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:

~/Library/Containers/com.microsoft.teams2/.../IndexedDB/https_teams.microsoft.com_0.indexeddb.leveldb

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.

Comparison with alternatives

Looking for an Apple MCP server alternative? LMCP is the zero-config, signed-app option that also covers Teams, Slack and WhatsApp.

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)
• One server for Mail, iMessage & Teams — yes, a single MCP server does all three, locally
• Microsoft Teams without Graph API — reads the local Teams cache, no Azure AD or admin consent
• WhatsApp on Mac — connect your AI to personal WhatsApp (no Business API)
• Connect ChatGPT to your Mac · Give Claude your email · Best MCP server for Mac

Privacy & security

• 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 — there is no cloud component to process your data
• Destructive operations always show a preview and require explicit confirmation

Supported AI clients

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 Zapier, Make, or n8n? Those route your data through their cloud. 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 cloud automation platform when you want hosted multi-step workflows.

How is it different from Composio or a Microsoft 365 / Graph connector? 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? Yes (beta): Outlook Mail/Calendar/Contacts, Microsoft To Do, OneDrive, Teams, Slack, Office (Word/Excel/PowerPoint/PDF), File Explorer, and Stocks.

How much does it cost? Free, no paid tier yet — a permanent license, not a 14-day trial, no subscription.

Roadmap

• Persistent AI memory across sessions

Have a feature in mind? Run request_feature from any AI client, or open an issue.

Uninstall

Run this in Terminal to completely remove LMCP:

curl -fsSL 'https://local-mcp.com/uninstall' | bash

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_bug or request_feature
• GitHub: open an issue
• Email: ctpo@colibird.co
• Website: local-mcp.com
