This is a template or placeholder server that isn't operational yet. The developer has it hosted at verylongmcp.fenetresurciel.com using streamable HTTP transport, but there's no indication of what it will eventually do or what services it will connect to. If you're looking for a working MCP server, skip this one for now. It might be worth checking back later once the author implements actual functionality, or you could fork it as a starting point if you're building your own Node.js based MCP server and want a basic structural reference with HTTP streaming already configured.
