Build stateful AI agents on Cloudflare Workers with persistent state, RPC methods, scheduling, and workflow orchestration. Your knowledge of the Agents SDK may be outdated. Prefer retrieval over pre-training for any Agents SDK task. Cloudflare docs: The Agents SDK provides: If not installed: For chat agents: Gotchas: Requests route to /agents/{agent-name}/{instance-name} : Client: useAgent({ agent: "Counter", name: "user-123" }) Custom routing: use getAgentByName(env.MyAgent, "instance-id") then agent.fetch(request) . - Core features include SQLite-backed state management, callable RPC methods via @callable() , one-time and recurring task scheduling, and durable multi-step workflows - Supports MCP server integration (both client and server modes), email routing with secure replies, and streaming chat with resumable streams on disconnect - Includes React hooks ( useAgent , useAgentChat ) for client-side state binding and real-time WebSocket communication - Agents route to /agents/{agent-name}/{instance-name} and validate state changes synchronously before persistence; always fetch current docs from the GitHub repository to stay current with SDK updates - Persistent state — SQLite-backed, auto-synced to clients via setState - Callable RPC — @callable() methods invoked over WebSocket - Scheduling — One-time, recurring ( scheduleEvery ), and cron tasks - Workflows — Durable...
