Originally published at HOL
The Universal Agent Registry now indexes 104,504 agents across 15 registries. This is the first edition of a monthly report we're publishing to track how the AI agent ecosystem is evolving — who's building, where they're building, and what's actually getting traction.
We aggregate data from MCP, A2A, ERC-8004, Virtuals Protocol, NANDA, OpenRouter, x402 Bazaar, and more via the Registry Broker API. The numbers below are a point-in-time snapshot.

Who's Leading
AgentVerse (Fetch.ai) holds the largest share at 36,338 agents (34.8%), followed by ERC-8004 (Ethereum) (18,344) and PulseMCP (16,510).
The ecosystem has 6 registries above 5% share and 7 still under 0.5% — early-stage protocols that are worth monitoring as they grow.

What Agents Are Built For
The registry tracks declared capabilities across all indexed agents. Here's what the current distribution looks like:
| Capability | Agents |
|---|---|
| Text Generation | 61,649 |
| API Integration | 32,013 |
| Workflow Automation | 8,348 |
| Data Integration | 7,790 |
| Knowledge Retrieval | 868 |
| Code Generation | 626 |
| Multi-Agent Coordination | 179 |
| Market Intelligence | 72 |
Text Generation dominates at 61,649 agents, but the spread across 19 distinct capabilities shows the ecosystem is diversifying beyond simple chatbots.
What's Next
This is the baseline. Starting next month, we'll track month-over-month growth across every registry and surface which protocols are gaining momentum — and which are stalling.
Highest Trust Scores
Trust scores are computed by the Registry Broker using availability, benchmarks, community reputation, and on-chain signals. These are the current top 5:
- Google: Gemini 3 Flash Preview — 100/100 (OpenRouter)
- Google: Gemini 2.5 Pro — 100/100 (OpenRouter)
- Google: Gemini 3 Pro Preview — 100/100 (OpenRouter)
- xAI: Grok 4.1 Fast — 100/100 (OpenRouter)
- Google: Gemini 2.5 Pro Preview 06-05 — 100/100 (OpenRouter)
