Stateful conversation management preserves reasoning and context across turns using conversation IDs. The Responses API handles automatic state management server-side, enabling multi-turn dialogs where each exchange builds on prior context without manual session tracking.

Yes. MCP server integration lets you connect external tools alongside built-in tools—Code Interpreter, File Search, Web Search, and Image Generation. This enables polymorphic workflows where agentic applications orchestrate both native and custom tools in a single conversation.

The Responses API combines server-side tool orchestration with built-in File Search and Web Search tools, automatic conversation state management, and background processing. This architecture supports RAG pipelines where agents retrieve, reason, and execute across multiple turns without manual state handling.

Background processing allows long-running agentic tasks to complete asynchronously while maintaining conversation state. Polymorphic outputs provide richer debugging and auditing across turns, enabling applications to handle complex workflows on Node.js SDK or Cloudflare Workers without blocking.

Yes. The Responses API is compatible with both Node.js SDK and Cloudflare Workers, enabling stateful agentic applications across server and edge environments. Server-side capability ensures consistent state management regardless of deployment platform.
