Adapter SDK to bridge agent frameworks to a shared A2A protocol

Overview
Provides an adapter SDK to connect different agent frameworks to a common A2A protocol. Implements client and server-side hooks so agents built on diverse runtimes (Python SDKs, workflow tools, or bot frameworks) can exchange messages and follow a shared A2A contract. Includes adapters and examples for popular stacks so integration requires minimal glue code. Agent-to-Agent Protocol (A2A)
The Value Proposition
As agents interact more with each other, a consistent A2A surface is required to observe, test, and compare behavior across implementations. This adapter SDK makes those interactions interoperable, enabling standardized logging, message shapes, and handshake semantics that feed evaluation and reputation systems. Without adapters, agent-to-agent evaluation and tracking is fragmented — adapters let you collect comparable signals across runtimes. Audit Trail
Ideal For
Developers integrating heterogeneous agent frameworks who need a common A2A protocol surface for testing, logging, or cross-agent orchestration. A2A protocol See also the interoperability baseline in Open Agent Specification (Agent Spec).
Applications
- When you need to instrument heterogeneous agents for consistent interaction logging and evaluation
- When you want to route messages between agents built on different frameworks without rewriting protocols
- When you need a baseline A2A client/server contract to feed reputation or RepKit-style tracking systems
