A native Swift server that hooks into macOS Messages and Contacts databases to give Claude read and send access to your iMessage history. Instead of raw SQL queries, you get 11 intent-aligned tools like find_chat, search, and get_messages with automatic contact resolution and session grouping. The attachment handling is smart: images come back as vision, thumb, or full variants to control token cost, and you can see what's local versus offloaded to iCloud before fetching. Useful when you need Claude to search conversations, pull context around specific messages, or send replies to exact threads after confirming recipients. Requires Full Disk Access for chat.db and Contacts permission for name resolution.
