H-Index is a Model Context Protocol (MCP) server: Capability registry for the agentic economy. Semantic search over verified MCP server listings. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.
It's a hosted (remote) server — point your client at https://h-index.xr-utilities.ai/mcp and you're connected, with nothing to install locally. The current release is v1.0.0.
You'll find H-Index in the Search category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below. If you maintain H-Index for xr-utilities.ai, claim this listing to verify ownership, earn the Verified badge, and keep the details current.
