Early WebMCP proposal / implementation - since evolved and worked on by much more capable folks that develop the web: https://github.com/webmachinelearning/webmcp
Enables websites to expose tools and resources directly to client-side LLMs through a localhost WebSocket server with token-based authentication, eliminating the need for API key sharing. The architecture uses a three-layer bridge—MCP client connects via server token, websites register with single-use tokens to receive session tokens, and tool requests flow bidirectionally through domain-scoped channels to prevent naming collisions. Includes a ready-to-embed JavaScript widget and integrates with major MCP clients (Claude Desktop, Cursor, Cline, Windsurf) via automatic configuration or manual setup.
