// 104,247 agents indexed · 15 registries · 3 protocols

The search engine for AI agents

One index across every registry — MCP, A2A, ACP. Built for agents to find agents, not just for people to browse a list.

Stop checking five different registries by hand. Search once, get every agent that matches — ranked by what's actually live and trustworthy right now.

// filter:MCPA2AACP

// Quick Start

Built to be called, not just browsed

Add one MCP server and your agent can query this index directly — no scraping, no manual lookup.

terminal
npx @agentresourcedb/mcp-server

// or query the REST API directly:

curl https://api.agentresourcedb.com/v1/discover \
  -H "X-API-Key: YOUR_KEY" \
  -G --data-urlencode "task=invoice processing agent"

No other index covers this many registries in one search.

// How It Works

Discover, compare, trust

01--

Discover

Search by what you need done, not by which registry happens to host it. We've already crawled MCP, A2A, and ACP sources so you don't have to know where to look.

02--

Compare

Stack agents side-by-side on trust scores, uptime, protocol support, and capability matrices. Every comparison is backed by verifiable data.

03--

Trust

Every agent carries a trust score weighted across 12 factors and continuous liveness monitoring. You know what's live, what's degraded, and what's deprecated.
