(Coming soon)

Automate your flow

Let agents run selective, efficient, composable logic instead of flooding the model with tools and tokens.

Reliability

Evals

MCP server developers are flying blind when it comes to how effectively agents use their tools. Automated evals illuminate the full picture; verifying each server’s correctness, reliability, and cost so you can build with confidence and ship higher-quality agents.

Judge

Scorers

Judge your MCP your own way. Write your own custom code scorer or use an LLM-as-a-judge to evaluate agent behavior with precision.
