How to Set Up and Use iMCP
iMCP is a native macOS menu bar app that turns your Mac's built-in Apple services—Calendar, Contacts, Messages, Reminders, Maps, Location, and Weather—into MCP tools that any AI assistant can call. It requires no code, no API keys, and no cloud services; it simply grants the AI structured access to data already on your device using macOS permission dialogs. Users install it once, enable the services they want, and their AI assistant can immediately answer questions like 'What meetings do I have tomorrow?' or 'Find John's phone number' using real local data.
Prerequisites
- macOS 15.3 (Sequoia) or later
- iMCP app downloaded from iMCP.app or installed via Homebrew
- Claude Desktop, Claude Code, Cursor, or Amp as your MCP client
- macOS system permissions granted for each service you enable (Calendar, Contacts, etc.)
Install iMCP
Download iMCP from the official site or install via Homebrew. The app places a menu bar icon in your macOS status bar.
brew install --cask mattt/tap/iMCP
# Or download directly from: https://imcp.app/downloadEnable desired services
Click the iMCP menu bar icon and click each service you want to activate (Calendar, Contacts, Location, Maps, Messages, Reminders, Weather). Grant macOS permission prompts as they appear. Active services show colored icons instead of gray ones.
Connect to Claude Code
Add iMCP as a user-scoped MCP server in Claude Code using the absolute path to the installed CLI binary.
claude mcp add --scope user iMCP -- /Applications/iMCP.app/Contents/MacOS/imcp-serverConnect to Claude Desktop
In Claude Desktop, go to Settings > Developer > Edit Config. Then in the iMCP menu bar app, click 'Configure Claude Desktop' to auto-populate the configuration.
{
"mcpServers": {
"iMCP": {
"command": "/Applications/iMCP.app/Contents/MacOS/imcp-server"
}
}
}Connect to Amp
Add iMCP to Amp using its CLI command.
amp mcp add iMCP -- /Applications/iMCP.app/Contents/MacOS/imcp-serverVerify the connection
Ask your AI assistant a question that requires one of the enabled services, such as checking your calendar. The assistant should return real data from your device.

}
}Prompts to try
Once iMCP is connected and services are enabled, try these natural language queries.
- "What meetings do I have tomorrow?"
- "Find John Smith's phone number in my Contacts"
- "What's the weather like where I am right now?"
- "Show me my reminders due this week"
- "How long does it take to drive from my current location to SFO?"
- "Read my last 5 messages from my sister"
- "Create a reminder to call the dentist on Friday at 10am"Troubleshooting iMCP
A service icon stays gray and the tool returns no data
Click the service icon in the iMCP menu bar to activate it, then grant the macOS permission prompt. If no prompt appears, go to System Settings > Privacy & Security and manually enable access for iMCP for the relevant category (Calendar, Contacts, etc.).
Messages tool cannot read message history
Messages require SQLite database access. When prompted, use the macOS file picker to grant iMCP access to ~/Library/Messages/chat.db. This is required due to macOS sandbox restrictions and cannot be automated.
imcp-server binary not found at /Applications/iMCP.app/Contents/MacOS/imcp-server
Verify iMCP is installed in /Applications (not ~/Applications). If using Homebrew, check the installed path with `brew info --cask mattt/tap/iMCP`. Update the path in your MCP client config accordingly.
