Overview
Implements a TypeScript Agent-to-Agent Protocol (A2A) with gRPC transport, AgentCard identity objects, task primitives, and a CLI for local testing. Provides a lightweight Node 22+ runtime SDK for agents to discover, authenticate, and exchange tasks over gRPC. Notable features include AgentCard-based identity metadata and a small CLI to spin up and inspect agent interactions. This stack also aligns with patterns like the Evaluation-Driven Development Pattern.
Key Benefits
As agents communicate directly, a shared protocol and identity model is foundational to any agent trust or reputation system. agent-to-agent-ts gives teams a concrete, interoperable A2A stack to log, inspect, and standardize interactions — the raw material you need to build agent track records and reputation signals. Until there are standard A2A fabrics, having a TypeScript reference with gRPC makes it easier to integrate evaluation and monitoring tooling into multi-agent flows towards a Multi-Agent System.
Ideal For
Developers prototyping agent-to-agent communication and collecting structured interaction data in Node.js environments, using approaches from the Event-Driven Agent Pattern.
Real-World Examples
- Prototyping agent-to-agent protocols and identity exchange with AgentCard
- Capturing structured interaction logs for downstream agent evaluation and reputation scoring
- Local testing of multi-agent task delegation flows using the provided CLI
