Registry, directory or marketplace: Best MCP Marketplace
Answer in brief
A registry lists, a client directory reviews, and a marketplace sells. Start in the one that matches what you need next.
A registry lists
The official MCP Registry is where servers publish their metadata, with a REST API for clients and aggregators to discover them. It is in preview.1
A client directory reviews
Claude's connectors directory lists over 950 MCP servers, and OpenAI reviews each plugin before it appears in ChatGPT and Codex.23
A marketplace sells
A marketplace adds buying. Conecto sells business tools per call from one balance, so an agent pays for what it uses.4

What should I verify first?
Decide whether you need to find a server, install a reviewed one, or buy usage, and start in that place.
