A managed agent runtime that layers your tools, agents and objectives so teams can test agent behavior safely and iterate fast.

Key features

  • Unified Tool Layer: Connect MCP servers, OpenAPI specs and existing endpoints once, and expose them to every agent through a single managed interface.
  • Model-Agnostic Variations: Set a default model and run canary variations on other providers side by side to compare behaviors before promoting a change.
  • Progressive Tool Discovery: Tool schemas stay out of the context window until an agent asks for them, with configurable max tools per search, search hints and a rerank threshold, so every request gets smaller.
  • Live Token Metering: Track cost as it accrues across loops, active variations, memory entries and widgets, so usage is visible rather than discovered on the invoice.
  • Webhooks and SSE Streaming: Push agent events — assistant messages, tool results, approval requests, sub-agent spawns, compaction, timeouts — into your own apps in real time.
  • Memory Layers: Attach stored documents such as playbooks and policy sets to an agent so its guidance persists across objectives.
  • Outcome Feedback Scoring: Collect scored comments on each objective, attributed to the variation and model that produced it, to see which behaviors actually work.
  • Embeddable Widgets: Drop an agent experience into any frontend as a widget rather than building the conversational surface yourself.

Best for

  • Operational Exception Handling: Run an agent that detects stalled shipments or orders and reroutes them through your dispatch API within policy.
  • Safe Model Migration: Evaluate a new frontier model as a canary variation against live objectives before switching the default.
  • Wrapping Existing APIs: Turn internal OpenAPI endpoints into agent-callable tools without rewriting the services behind them.
  • Embedding Agent Chat in a Product: Ship a conversational agent surface into an existing frontend using widgets instead of building it in-house.
  • Cost Control at Scale: Use progressive discovery and live metering to keep context size and per-loop cost down as agent traffic grows.
  • Agent Quality Review: Compare scored feedback across variations to understand which prompt or model changes improved real outcomes.
