Summary
This server wraps the official MCP Registry API so you can query available servers programmatically from within your AI assistant. It exposes tools to list all registered servers with search filters, fetch version histories for specific packages, pull detailed metadata for any server version, and run health checks against the registry. You'd reach for this when building workflows that need to discover or validate MCP servers on the fly, or when you want your assistant to recommend servers based on current registry data instead of stale training knowledge. Setup is just npx with stdio transport, and it handles pagination and filtering automatically.

A Model Context Protocol (MCP) server that provides tools to query the official MCP Registry. This server enables AI assistants and applications to discover, search, and retrieve information about published MCP servers programmatically.
✨ Features
- 🔍 List Servers: Browse all registered MCP servers with pagination
- 🔎 Search: Find servers by name with filtering options
- 📦 Version Management: View all versions of specific servers
- 📝 Detailed Information: Get comprehensive server details
- 💚 Health Checks: Monitor registry availability
🚀 Quick Start
Other Clients
Sample configuration (double check the documentation of your MCP client for exact syntax and file locations):
{
"mcp-registry-mcp-server": {
"type": "stdio",
"command": "npx",
"args": ["-y", "mcp-registry-mcp-server"]
}
}
📚 How to Use
Once configured, you can ask your AI assistant natural language questions like:
- "What new MCP servers have recently been released?"
- "Search for filesystem-related MCP servers"
- "Show me the latest version of the github-mcp-server"
- "Get details about the Chrome DevTools MCP server"
- "Is the MCP registry healthy?"
The AI will automatically use the appropriate registry tools to answer your questions.
