Real-time observability for agent-to-agent protocol communications. Monitor, analyze, and optimize how your AI agents talk to each other.
Purpose-built for the Agent-to-Agent protocol. Every message, every task lifecycle, every agent card discovery — captured, indexed, and visualized.
Full distributed tracing across agent-to-agent request chains. Follow a task from client initiation through server execution, across multiple agent hops.
Live topology of your agent network. See which agents are discovering each other via Agent Cards, their capabilities, and connection health.
Track tasks through every state transition — submitted, working, input-required, completed, failed. Identify bottlenecks and failure patterns.
Inspect every artifact produced by remote agents — documents, images, structured data. Content-type negotiation visibility included.
See both MCP tool calls and A2A agent communications in a single timeline. Understand the full picture of how your agents work.
Real-time monitoring of Server-Sent Events streams between agents. Measure throughput, detect dropped connections, track partial results.
Drop the A2A Traffic agent into your existing multi-agent system. No code changes required.
Add the A2A Traffic agent to your ecosystem. It discovers peers through standard Agent Card exchange.
Transparent proxy layer captures all JSON-RPC messages, SSE streams, and push notification payloads between agents.
Real-time dashboards show agent health, message flow, and task completion rates. Smart alerts on anomalies.
Use insights to improve agent coordination, reduce latency, and scale your multi-agent system with confidence.
The Agent2Agent (A2A) protocol, launched by Google and now maintained by the Linux Foundation, is the open standard for AI agents to communicate across platforms, frameworks, and vendors.
A2A Traffic sits at the observation layer of this protocol — giving you full visibility into how agents discover capabilities via Agent Cards, negotiate content types, manage long-running tasks, and stream results via SSE.
While MCP handles agent-to-tool connections, A2A handles agent-to-agent collaboration. A2A Traffic monitors both.

A2A Traffic doesn't live inside the [&] capability composition — it sits above it. The observability layer that sees every agent handshake, every task delegation, every message bounce across the entire stack.
Every agent in the [&] portfolio speaks A2A. FleetPrompt orchestrates them. Agentelic builds them. SpecPrompt defines them. WebHost.Systems runs them.
A2A Traffic is the only thing that sees all of it happen — every JSON-RPC call, every Agent Card discovery, every SSE stream, every task state transition across the entire composition.
Think of it as the final line on ampersandboxdesign.com — the quiet reveal that says: "oh, and we can see everything."
SEE THE FULL [&] STACK →A2A Traffic gives you eyes on every agent-to-agent interaction in your system. The protocol is open. Your visibility shouldn't be blind.
