Direct Answer Definition

Agent registries are the production-grade directories where autonomous AI agents discover business capabilities — the machine-economy equivalent of Google My Business, rebuilt for AI crawlers instead of human eyes. Three major registries are live in production: (1) Google Cloud Agent Registry, shipped via the gcloud alpha agent-registry CLI integrated with Google's Agent Development Kit (ADK), indexes agent-card.json manifests directly into the search framework powering Google Assistant and Gemini's native checkout. (2) AWS Bedrock AgentCore Runtime includes a native AWS Agent Registry for enterprise B2B capability matchmaking, where corporate orchestrators programmatically search for verified vendor capabilities using IAM-managed access tokens. (3) Microsoft Entra Agent ID treats autonomous agents as first-class identity citizens inside corporate networks, verifying security boundaries and cryptographic signatures via a core directory. For the open web, a2aregistry.org provides a community-driven global clearinghouse, while Cloudflare Bot Management distributes Signature Agent Registries that parse .well-known intent cards and build verified whitelists. Slickrock.dev builds the endpoints that get listed in these registries — wrapping legacy infrastructure into ADK-compliant servers that output signed agent-card.json manifests.

Frequently Asked Questions

How is an agent registry different from Google My Business?

Google My Business is built for human eyes — reviews, maps, and website links. Agent registries are built for machine crawlers — they index cryptographically signed agent-card.json manifests containing structured capability schemas, protocol compliance declarations, and authentication constraints that AI agents parse programmatically.

Do I need to register with every agent registry separately?

No. You host a single /.well-known/agent-card.json on your domain. Each registry crawls and indexes it automatically, similar to how Google indexes your website via a single sitemap.xml. SlickRock.dev builds the compliant endpoint once, and all registries discover it.

What happens if my business isn't in any agent registry?

You are structurally invisible to the machine economy. When a consumer's AI assistant or a partner's procurement agent searches for a capability, your business will not appear in results. This is the equivalent of not having a website in 2005.
