claude-sync
Local-first MCP server for multi-Claude agent coordination
What is this?
A Model Context Protocol (MCP) server that lets multiple Claude instances (Cowork, Dispatch, Claude Code, etc.) coordinate through a shared local message bus.
Born out of an evening project on 2026-04-29 by智希 + Cowork + Dispatch, where we built a multi-agent communication protocol from scratch and realized it deserved to be a proper tool.
