openclaw-a2a-gateway is a plugin by win4r that implements the A2A (Agent-to-Agent) v0.3.0 protocol for OpenClaw, enabling bidirectional communication between separate agent instances. With zero-config setup, it allows OpenClaw agents to discover and message each other without manual endpoint registration or custom networking code.
The A2A protocol standardizes how autonomous agents communicate across different runtimes and providers. By implementing v0.3.0, this plugin makes OpenClaw agents first-class participants in multi-agent networks that include non-OpenClaw agents — any system implementing the same protocol can interoperate. This is particularly useful for hybrid architectures where OpenClaw handles one role (e.g., user-facing chat) while a specialized agent handles another (e.g., data retrieval or code execution).
The plugin is actively maintained by win4r as part of their broader OpenClaw integration portfolio. It pairs naturally with ClawTeam-OpenClaw for fully orchestrated multi-agent deployments, but can also be used standalone to add A2A capabilities to a standard OpenClaw install.
