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.

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

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_bugorrequest_feature - GitHub: open an issue
- Email: ctpo@colibird.co
- Website: local-mcp.com
