Overview

Implements the Agent2Agent (A2A) protocol in .NET to enable secure, interoperable communication between autonomous agents. Provides a JSON-RPC-based messaging stack, authentication/authorization hooks, and pluggable transport adapters so agents across frameworks can exchange structured messages. Notable for a C# SDK and reference server patterns that make it easy to adopt A2A in .NET agent projects. This repository also aligns with established patterns like reference server patterns.

The Value Proposition

As agents talk to other agents, a common, secure transport is required to compare behavior, log interactions, and build reputations. A standard A2A implementation makes agent-to-agent evaluation and cross-framework traceability practical by producing consistent, inspectable message traces. This repository helps teams standardize communication so tools like reputation trackers and evaluators can consume the same interaction signals across vendors, guided by the A2A protocol pattern.

Ideal For

.NET/C# teams who need a reference A2A implementation to connect heterogeneous agents and emit consistent interaction logs for evaluation. Learn from the Agent-to-Agent Protocol (A2A) reference as you adopt the approach.

Applications

Standardize inter-agent messaging across .NET services to enable cross-framework evaluation
Emit consistent JSON-RPC interaction logs for downstream reputation or evaluation systems
Integrate secure agent communication into production .NET agent frameworks with pluggable transports
