Cloudflare Agents

What it is

An SDK for building AI agents as persistent, stateful units on Cloudflare Workers, each backed by a Durable Object with its own SQLite storage. It covers real-time state sync over WebSockets, scheduled tasks, durable workflows with human approval, AI chat with resumable streaming, MCP servers and clients, voice, email, and sandboxed code execution. Developers building per-user or per-session agents on Cloudflare use it along with React hooks and a plain JavaScript client to connect frontends.
