Universal Native MCP Server Hub

Universal Model Context Protocol (MCP) Server Hub for Claude Code, Cursor, Windsurf, and Antigravity

With the rise of autonomous coding assistants and agents (Claude Code, Cursor, Windsurf, Antigravity, CrewAI, LangChain), the Model Context Protocol (MCP) has become the universal standard for tool calling.

Instead of installing 19 separate local servers or bloated Docker containers, Universal Native MCP Server Hub bundles 19 production-grade AI primitives into a single serverless edge hub running with 0ms cold-start latency across 300+ global Cloudflare locations.
