Ness Gate MCP Server

Give NessGate a domain and your client's capabilities, and it tells you how that client can connect - and what's still missing. One call turns "here's a domain" into a concrete, sourced connection plan: which protocol to use, at which endpoint, over which transport, and exactly what authentication the service published - or, if it can't be done yet, the precise field the service is missing.

Teams that work with a2a, agentic web and ard and want a hosted endpoint instead of running a local process. The project is written in JavaScript.
