@callable RPC methods, and automatic client state sync via React hooks like useAgent. - Chat & Streaming: Build streaming chat agents with AIChatAgent, resumable streams, tool calling, and human-in-the-loop approval flows. - Background Processing: Run durable Workflows, FIFO queues with retries, cron scheduling, and fibers that survive Durable Object eviction. - Integrations: Connect to or build MCP servers, handle email routing, webhooks, push notifications, voice (STT/TTS), and browser automation. - Use Case: Build a customer support chat agent that persists conversation history, schedules follow-up reminders, calls MCP tools, and streams responses to a React frontend. ## Quick Start Use the agents-sdk skill to create a Cloudflare Worker agent class with persistent state and a callable RPC method, then connect it to a React client.High-intent search queries and answers about installing and using this skill.
Extend the Agent class from the agents package, define typed state with initialState, and expose methods with @callable. Configure a Durable Object binding and a new_sqlite_classes migration in wrangler.jsonc, then route requests with routeAgentRequest.
Use AIChatAgent from @cloudflare/ai-chat and implement onChatMessage with streamText from the AI SDK. Pass abortSignal and onFinish for proper cleanup and message persistence; streams resume automatically on client reconnect.
Yes, agents include a multi-server MCP client via this.addMcpServer, supporting OAuth flows and Streamable HTTP, SSE, or RPC transports. You can also build MCP servers using the McpAgent class with the @modelcontextprotocol/sdk package.
Enabling experimentalDecorators in tsconfig conflicts with the decorators used by the Agents SDK and breaks @callable methods. Extend the agents/tsconfig configuration instead, which applies the correct compiler settings.
Use the built-in queue() for background tasks under 30 seconds with FIFO ordering. Use AgentWorkflow for long-running multi-step tasks, automatic retries, and human-in-the-loop approval flows that must survive failures.
