Cloudflare Agents

This is Cloudflare's official framework for building AI agents that run on Workers. You get tool registration, streaming responses, and bindings for D1, KV, R2, and Durable Objects baked in. The documentation is comprehensive with 13 templates covering everything from basic agents to browser automation, RAG, and MCP integration. It supports OpenAI, Anthropic, and Google models out of the box. If you're already on Cloudflare's platform and want to build agentic workflows without managing separate infrastructure, this gives you a batteries-included approach. The state management and workflow guides are especially thorough at 388 and 637 lines respectively, which suggests they've thought through the hard parts of running stateful agents at the edge.
