What is the MCP Catalog MCP server?

MCP Catalog MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. MCP server for searching and discovering 24,500+ MCP servers and AI agents. Semantic search, trust scores, vulnerability tracking.

What you get

MCP server that connects your AI assistant to the KnyazevAI search engine — the largest unified index of MCP servers and AI agents (24,500+ entries across 8 registries).

What the assistant can call

Once MCP Catalog is connected, these are the calls the assistant has available:

  • search_servers — Semantic search by task description
  • list_servers — Browse with filters (category, sort)
  • get_server — Get full details by server UUID
  • discover — Task-based search across MCP + A2A agents
  • get_server_vulnerabilities — Check CVE/GHSA for a server
  • get_catalog_stats — Catalog overview

Setting it up

The server ships on npm as knyazevai-mcp-catalog, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

Choosing this one

Plenty of planning and project tracking servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. MCP Catalog's toolset — search_servers, list_servers, get_server and 3 more — is a fair guide to whether it matches your workflow. It is maintained by knyazev741; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the mcp catalog mcp server does with a few real requests.

Frequently asked questions

It connects MCP Catalog to MCP-compatible AI assistants such as Claude and Cursor, exposing 6 tools (search_servers, list_servers, get_server, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with MCP Catalog directly.
