MCP

CrewAI 1.15.23 lets your agent pipelines be scored in production and survive rate limits — tracing-based evaluation scores each run, and throttled model calls now retry automatically. If agents carry campaign work, upgrade in staging first.

promptfoo shipped version 0.123.0 — the open-source eval harness now covers the latest frontier models, but a default switch for newer GPT models breaks some existing test configs. If you run model evals, test before upgrading.

Google shipped stateless updates to MCP that let agents scale horizontally without sticky session state — if you're pushing marketing agents toward production, this removes a core infrastructure bottleneck that has made concurrent personalization and lifecycle workflows hard to parallelize.

Three platform ships this week lower the barrier for deploying AI agents in marketing workflows — Google's MCP stateless scaling, Vercel's Claude Managed Agents in Chat SDK, and Vercel's dashboard agent deployment. But Twilio's data showing 78% of consumers actively bypass AI agents is a reminder that infrastructure readiness and consumer willingness are different problems.

Langfuse shipped a rebuilt eval experience, LangChain patched a Claude agent crash mode, and Supabase plus Bedrock added infrastructure for governed, context-aware agents — all relevant if you ship AI in marketing systems.

Google shipped a production-ready agent evaluation service in Gemini Enterprise this week — the first turnkey option for teams that need to measure agent quality without building custom testing infrastructure from scratch.
