# Cloudflare Agents A platform and SDK for developers building AI agents with persistent state and tools. - Findings24: - ウェブサイト: - 料金: Freemium - カテゴリー: AIエージェントビルダー, AIエージェント基盤, AI SDK ## Cloudflare Agentsとは？ Cloudflare Agents is Cloudflare’s platform for building AI agents that receive input, reason with language models, retain state, and act through tools. It brings together the Agents SDK and Cloudflare services for inference, execution, storage, and communication. Developers can run models with Workers AI or connect to external providers through AI Gateway. Durable Objects and Workflows support stateful, multistep execution, including returning to a model to revise a plan. The platform is suited to applications that coordinate ongoing tasks across APIs, user interactions, and scheduled actions. ## Cloudflare Agentsでできること ### Email, chat, and voice input Receive input through Email Workers, WebSockets and Workers, or Cloudflare Calls, allowing agents to participate in different communication channels. ### Model hosting and provider connections Use Workers AI for inference on Cloudflare or AI Gateway to connect to external model providers for planning, reasoning, and content generation. ### Persistent state and workflow execution Combine Durable Objects for state with Workflows for compute to carry out multiple steps and revisit decisions as new variables emerge. ### Tools for external actions and data access Connect agents to APIs through MCP servers and use Browser Rendering, Vectorize, and D1 to interact with web content, vector data, and databases. ### Scheduled actions and shared state The SDK example demonstrates scheduled methods, callable agent methods, and state updates sent to connected users, supporting recurring tasks and collaborative interactions. ### WebSocket hibernation Durable Objects can shut down during inactivity while maintaining WebSocket connections, reducing the cost of agents with long-lived connections. ## 利用シーン ### Collaborative lunch selection An office lunch agent can research nominated restaurants, store menus in Vectorize, collect coworkers’ votes, and generate an announcement explaining the selected option. ### Remote MCP servers Developers can use the Agents SDK to build remote MCP servers. The homepage cites Knock’s use of the SDK to ship a server for its customers. ### Tasks that wait on external responses Build agents whose work includes LLM calls, API requests, or human input. Persistent state and execution services support tasks that span these waiting periods. ## よくある質問 ### How does Cloudflare describe agentic AI? It describes agents as systems that plan, iterate, and interact with their environment to achieve objectives, extending beyond generating responses to individual prompts. ### How does usage-based billing apply to agents? The homepage describes Workers AI as charging for usage and Workers execution billing in terms of CPU time rather than time spent waiting on I/O. It also highlights Durable Objects WebSocket hibernation as a way to reduce idle connection costs. ### What does the SDK code example show? The TypeScript example extends Agent, marks methods with @callable(), schedules recurring actions, starts a restaurant research workflow, updates voting state, and calls a Workers AI model to compose the lunch result. ## クイック情報 - **Product category**: AI agent development platform and SDK - **Provider**: Cloudflare - **Primary users**: Developers building agent applications and remote MCP servers - **Example language**: TypeScript - **Official website**: https://agents.cloudflare.com/
