What is an MCP client? It is the part inside apps like Claude, Cursor and VS Code that opens one connection to one MCP server to fetch tools and data.

Why we built a single directory for AI agents, MCP servers and agent skills, and how to get your product listed.
The agentic AI ecosystem has exploded into three interlocking layers: AI agents that do the work, MCP servers that connect them to tools and data, and skills that extend what they can do. Discovery, however, is still fragmented: agent directories ignore MCP servers, MCP registries ignore agents, and skills mostly live in scattered GitHub readmes.
AI Agents Listing indexes all three verticals in one place and cross-links them, so you can go from an agent to the MCP servers it works with, or from a skill to the agents that support it.
Each listing has a structured profile: what it does, category, links, screenshots and setup notes. Listings are free to submit, and makers can claim their page, upgrade placement or feature their product.
If you build agentic tooling, submit your product. It takes less than five minutes.
One email a week. New agents, MCP servers and skills, and what is actually getting traction.
