MCP Registry Search

Semantic search API for MCP servers using the official Model Context Protocol registry.

Use as:

• REST API (search): https://mcp-registry-search.vercel.app/search?q=kubernetes&limit=2
• REST API (list): https://mcp-registry-search.vercel.app/servers?limit=10&offset=0
• MCP Server (SSE): https://mcp-registry-search.vercel.app/api/sse

Cron job reindexes the entire registry every night.

Built with:

• mcp-agent cloud
• Supabase
• Vercel

Endpoint: https://mcp-registry-search.vercel.app/api/sse

Available Tools:

• search_mcp_servers(query, limit, full_text_weight, semantic_weight) - Search servers using hybrid search
• list_mcp_servers(limit, offset) - List all servers with pagination

Add to your MCP client config:
