plugin Software development

The agent eval standard for MCP. Score every agent output for quality, safety, and cost. 12 built-in eval rules cover completeness, relevance, safety (PII detection, prompt injection), and cost thresholds. Log traces with hierarchical spans, evaluate outputs inline, and track costs across all your agents. No SDK, no code changes — add one line to your MCP config. Open source, MIT licensed.
