Stateful AI agents use Cloudflare Durable Objects paired with SQLite storage to maintain agent state across requests. Each agent instance gets up to 1GB of persistent storage, enabling you to store conversation history, user context, and workflow state without external databases.

Yes. Cloudflare Durable Objects support bidirectional WebSocket connections for real-time agent interaction. Combined with Server-Sent Events (SSE), you can build chat interfaces, live notifications, and event-driven workflows that communicate instantly with clients.

Cloudflare's scheduling APIs let you set cron jobs, fixed delays, and specific date triggers directly on Durable Objects. This enables agents to execute background work like polling, cleanup, or proactive notifications without external task queues.

Cloudflare Agents SDK supports multi-agent coordination through Durable Objects that can communicate with each other. Use message passing and shared state patterns to orchestrate workflows, delegate tasks, and synchronize work across multiple agent instances.

Yes. The SDK works with OpenAI, Anthropic, and Model Context Protocol servers. Bind these dependencies to your Worker to add language models and external tools, enabling agents to make decisions and take actions beyond local state management.

Per-agent SQLite storage maxes at 1GB, and Workers have CPU time limits per request. For long-running tasks, use scheduled APIs and delays. WebSocket connections rely on Cloudflare's infrastructure availability, so design agents to gracefully handle disconnects.
