iMCP is a macOS application that provides an MCP server (named iMCP) to connect your digital life with AI. It bundles a command-line executable, imcp-server, that speaks the MCP protocol over a stdio transport. The app and CLI communicate locally via Bonjour for automatic discovery, with both advertising a local _mcp._tcp service. The project leverages the official Swift SDK for MCP servers and clients, and includes Madrid for reading the iMessage database (chat.db) via a typedstream reader. It exposes a curated set of capabilities—Calendar, Contacts, Location, Maps, Messages, Reminders, and Weather—each requiring macOS permissions and toggle-able activation in the UI. Importantly, iMCP does not collect or store user data; however, some data may be sent off-device by MCP clients like Claude Desktop during tool calls. Claude Desktop can be configured automatically through Settings → Developer → Edit Config to use the imcp-server, or manually by copying the server command into claude_desktop_config.json. The project also supports debugging tools such as the MCP Inspector and Companion for testing and exploration, and runs in App Sandbox to minimize data access. Tools return JSON-LD documents, enabling structured data exchange.
