Getting Started
Download and open the app
First, download the iMCP app
(requires macOS 15.3 or later).
Or, if you have Homebrew installed,
you can run the following command:
When you open the app,
you'll see a
icon in your menu bar.
Clicking on this icon reveals the iMCP menu,
which displays all available services.
Initially, all services will appear in gray,
indicating they're inactive.
The blue toggle switch at the top indicates that the MCP server is running
and ready to connect with MCP-compatible clients.
Activate services
To activate a service, click on its icon.
The system will prompt you with a permission dialog.
For example, when activating Calendar access, you'll see a dialog asking "iMCP" Would Like Full Access to Your Calendar.
Click Allow Full Access to continue.
> [!IMPORTANT]
> iMCP **does not** collect or store any of your data.
> Clients like Claude Desktop _do_ send
> your data off device as part of tool calls.
Once activated,
each service icons goes from gray to their distinctive colors —
red for Calendar, green for Messages, blue for Location, and so on.
Repeat this process for all of the capabilities you'd like to enable.
These permissions follow Apple's standard security model,
giving you complete control over what information iMCP can access.
