Summary
Implements a peer-to-peer agent communication mesh for A2A (agent-to-agent) messaging in Go. Provides a concrete MCP-style transport and discovery layer that routes, encrypts, and multiplexes agent messages across a secure mesh. Notable features include p2p mesh networking primitives, connection management, and focus on secure agent interoperability. Agent-to-Agent Protocol (A2A) and Capability Discovery Pattern.
Key Benefits
As agents communicate and delegate work to other agents, a consistent and auditable transport layer is essential for trust and evaluation. SAM supplies a standardized A2A/mcp implementation so you can record, inspect, and enforce message flows between agents—making agent interaction logs and provenance easier to gather. Until now teams often stitched custom networking code; a reference mesh helps align instrumented communications for reputation and evaluation tooling. Human-in-the-Loop Pattern.
Ideal For
Teams building distributed agent systems that need a reference Go implementation of secure A2A/mcp networking for interoperability and auditability. Open Agent Specification (Agent Spec)
Use Cases
- Bootstrapping a secure peer-to-peer transport for multi-agent systems
- Capturing agent interaction logs and transport-level metadata for evaluation
- Prototyping interoperable A2A communication that conforms to MCP-style semantics
