Every TypeScript agent SDK I tried treated Azure OpenAI as a second-class citizen. Stratus flips that. It's built Azure-first and includes everything you'd expect: tools, subagents, handoffs, sessions, streaming, structured output with Zod, guardrails, hooks, tracing, and MCP client support. Plus Code Mode, which lets the model write code to orchestrate tools in a loop instead of one call per turn. If you're on Azure and tired of adapter tax, this is for you.

Hey everyone, I built Stratus because every TypeScript agent SDK I tried treated Azure OpenAI as a second-class citizen. Adapters, quirks around the Responses API, features that silently didn't work on Azure deployments. So I built one that starts from Azure instead of bolting it on. It has what you'd expect: agents, tools, subagents, handoffs, sessions, streaming, Zod-based structured output, guardrails, hooks, tracing, and MCP client support. The piece I'm most curious to see in the wild is Code Mode, where the model writes code to orchestrate your tools in a loop instead of doing one call per turn. Big latency win for complex workflows. It's open source and on npm as @usestratus/sdk. Would love feedback from anyone building on Azure.
