mcp-server-mcpindex

An MCP server for finding MCP servers.

A drop-in MCP server that lets your agent discover, compare, and install other MCP servers from inside the agent loop. Backed by mcpindex.ai — the agent-native index of 3,500+ MCP servers indexed daily from the official registry.

Install

npm install -g mcp-server-mcpindex

Use it from Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "mcpindex": {
      "command": "npx",
      "args": ["-y", "mcp-server-mcpindex"]
    }
  }
}

Restart Claude Desktop. Then ask:

"Find me an MCP server that can read PDFs and write the contents to S3."

Claude calls recommend_mcp_for_task and returns the top 3 ranked servers with install commands.

Use it from Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "mcpindex": {
      "command": "npx",
      "args": ["-y", "mcp-server-mcpindex"]
    }
  }
}

Use it from Cline

Add to your Cline settings:

npx -y mcp-server-mcpindex
