What It Does

Implements a local-first bridge for the Hermes Agent-to-Agent (A2A) HTTP+JSON subset so agents can exchange messages over a minimal A2A API. Exposes a lightweight HTTP JSON endpoint that translates Hermes agent messages to the A2A shape, enabling local dev and LAN-based multi-agent interactions. Distinctive for being local-first and simple to run as a small Python bridge for testing and integration. Event-Driven Agent Pattern

The Value Proposition

As agents communicate with one another, having a small, local A2A bridge makes it easy to exercise agent-to-agent flows without deploying infrastructure. This repo lowers friction for debugging interactions, logging exchanges, and validating message shapes — all useful signals when building agent track records or running A2A evaluation. Until you can reliably simulate and capture inter-agent traffic, trust and reputation assessments remain speculative; lightweight bridges like this let teams reproduce real interaction patterns locally. Audit Trail Model Context Protocol (MCP)

When to Use

Developers who need a simple, local A2A-compatible HTTP bridge to test Hermes agent message flows and capture interaction logs. Agent Protocol

Applications

  • Replay and inspect Hermes agent message exchanges locally for debugging
  • Validate A2A HTTP+JSON message shapes before deploying multi-agent systems
  • Capture inter-agent logs to feed into A2A evaluation or reputation tooling
