I've seen a number of them. Some are a simple listing, others do some level of validation and ranking based on various heuristics, others are an actual service that will run the mcp servers for you in an encapsulated form so that it becomes more of an app store-like experience and you don't need to do manual configuration in your client. mcp.run is basically this - they run the servers in a webassembly sandbox for you. I'm probably not doing it real justice, but it's a really interesting concept in a very interesting space(MCP) right now.
