Show HN: Agent Hub MCP – Universal coordination system for AI coding assistants

Agent Hub MCP enables ANY MCP-compatible AI assistant to coordinate across repositories and platforms. Think message broker + shared state for multi-vendor AI agents.

Key insight: AI agents work better when they can communicate, regardless of the underlying platform. Mix Claude Code, Qwen, Gemini, Cursor - they all coordinate through the same hub.

Example: Qwen discovers API patterns → shares with Claude Code → both coordinate with Gemini for documentation → end-to-end feature delivery.

Platform agnostic via Model Context Protocol. One-line setup for any MCP client. Production ready with TypeScript and comprehensive testing.
