H Index
Semantically discover verified MCP servers and capabilities when you are assembling or extending your agent stack.
Overview
H-Index is a Build-phase MCP server that provides semantic search over verified MCP server listings as a capability registry for agents.
What is this MCP server?
- Streamable HTTP remote at https://h-index.xr-utilities.ai/mcp
- Semantic search over verified MCP server listings
- Positioned as a capability registry for the agentic economy
- Useful when comparing MCP options instead of scrolling static directories
- Server version 1.0.0 from ai.xr-utilities/h-index
- Remote: streamable-http at h-index.xr-utilities.ai
- Focus: verified MCP server listings (count not stated in manifest)
What problem does it solve?
The MCP ecosystem is noisy and duplicate-heavy, so picking a verified server for your next integration wastes hours of manual directory scrolling.
Who is it for?
Solo builders assembling MCP stacks who want agent-native discovery of verified servers across the journey.
Skip if: Builders who already know one fixed server URL and only need execution tools, not a registry search layer.
What do I get? / Deliverables
Your agent can semantically search verified MCP listings and narrow stack choices before you commit config slots in your client.
- Ranked MCP server candidates from semantic registry search
- Shorter shortlists for integration design in agent projects
- Documentation pointers to verified listings before you wire remotes
Recommended MCP Servers
Journey fit
Build/agent-tooling is the canonical shelf because the registry exists to help you pick and wire MCP capabilities while implementing agents—not to run marketing analytics. Agent-tooling matches a capability registry: semantic search over verified listings supports tool selection, stack design, and iteration on integrations.
How it compares
MCP capability registry and search MCP, not a domain data connector like analytics or social APIs.
Common Questions / FAQ
Who is H Index for?
Indie developers and agent authors who need to find and evaluate verified MCP servers without manually combing GitHub and static lists.
When should I use H Index?
Use it whenever you are discovering tools, planning integrations, or refactoring which MCP remotes your agent loads.
How do I add H Index to my agent?
Register the streamable HTTP endpoint https://h-index.xr-utilities.ai/mcp in your MCP client, then ask your agent to search the registry for capabilities matching your task.
