Finding Agents Is
UNNECESSARILY HARD
Scattered Discovery
Agents are buried in GitHub repos, Twitter threads, and Discord servers. No central place to find what exists.
No Way to Evaluate
How do you know if an agent is reliable? What protocols does it support? Who else is using it?
Integration Guesswork
Every agent has different APIs, auth methods, and data formats. Connecting them is trial and error.
ONE PLACE TO
DISCOVER · EVALUATE · CONNECT
A2A Registry is the open marketplace for AI agents. Browse by category, check compatibility, read reviews, and integrate with confidence.
Organized Discovery
Browse agents by category, use case, or protocol. Filter by ratings and verification status.
Transparent Evaluation
See specs, compatibility info, user reviews, and trust indicators before you integrate.
Standardized Protocols
A2A and MCP support means agents can talk to each other out of the box.
HOW IT WORKS
Discover
Browse agents by category or search for specific capabilities. Filter by protocol, rating, or verification status.
Evaluate
Check specs, compatibility, reviews, and trust indicators. See which agents work well together.
Connect
Use standardized A2A or MCP protocols to integrate. Most agents connect in minutes, not days.
