Overview
SUMMARY: Lists and indexes live, hosted AI agents that speak the A2A protocol. Open Agent Specification Curates community-submitted agent endpoints, metadata, and status so you can discover running agents and their capabilities. Capability Discovery Pattern Focuses on real-world availability rather than synthetic examples, making it easy to find agents to connect or evaluate.
The Value Proposition
WHY IT MATTERS: As agent ecosystems grow, discovery of real, running agents is a bottleneck for testing trust and interoperability. A community registry surfaces who is actually online, what interfaces they expose, and basic provenance information — data critical for agent-to-agent evaluation and tracking agent track records. Agent Registry Pattern Without such a directory, testers and integrators spend time reimplementing connectors or guessing compatibility.
Ideal For
BEST FOR: Developers and researchers who need to discover and connect to live A2A agents for testing, integration, or evaluation. Open Agent Specification
Applications
- Find running A2A agents to include in agent-to-agent evaluation or RepKit-style experiments
- Discover agent endpoints and metadata for integration into multi-agent orchestration or testing pipelines
- Verify agent availability and provenance before running continuous agent evaluation or benchmark suites
