Keep the instrumentation you have
Your existing agent
Your agent runs in your own process; Hue hosts the simulated apps it calls.
The same tools
Connect your agent to Hue simulations just as it connects to the real apps: API, MCP, Composio, Pipedream, and more.
Traces from any OpenTelemetry tool
Bring traces through Hue’s SDKs or OpenTelemetry to reconstruct the app state they capture.
