Features

  • Zero Boilerplate: Dynamically parses OpenAPI paths into standard MCP tool schemas on the fly.

  • Backend Architecture: Powered by a real-time, isolated multi-account routing pipeline using Supabase and Render.

  • Protocol Compliant: Handshakes cleanly with the official MCP Inspector for tool listings, discovery, and execution.

Note: The core routing and isolation engine codebase for this gateway is maintained in a private repository for security infrastructure purposes.

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd
