Braintrust released an official MCP server empowering developer coding agents to inspect production telemetry, convert failed traces into regression datasets, and continuously score prompt diffs.

Key Takeaways

  • Protocol-driven observability: allows existing developer agents to query telemetry directly via MCP;
  • Automated regression pipeline: converts failed trace spans into permanent golden eval datasets programmatically;
  • Unifies cost, latency, and behavioral evaluation into actionable telemetry for iterative prompt engineering.
