iMessage MCP is a Deno-based monorepo providing a robust solution for accessing iMessage conversations and macOS contacts directly from your computer. It features a core library for read-only database access and a Model Context Protocol (MCP) server specifically designed for seamless integration with Large Language Models (LLMs). This allows external applications to programmatically search messages by content, contact, or date, list chats, retrieve contacts, and access specific conversations, all while ensuring data security with its read-only design.
