Functionary provides a declarative way to register custom tools — JavaScript functions encapsulating API calls, database queries, or business logic. It wraps an LLM interaction to analyze user prompts, determine which tools to execute, and parse the tool outputs back into conversational responses. The framework supports memory, error handling, and chaining of actions, offering hooks for pre- and post-processing. Developers can quickly spin up agents capable of dynamic function orchestration without boilerplate, enhancing control over AI-driven workflows.

Cloudflare Agents is an AI agent platform built on top of Cloudflare Workers, offering a developer-friendly environment to design autonomous agents at the network edge. It integrates with leading language models (e.g., OpenAI, Anthropic), providing configurable prompts, routing logic, memory storage, and data connectors like Workers KV, R2, and D1. Agents perform tasks such as data enrichment, content moderation, conversational interfaces, and workflow automation, executing pipelines across distributed edge locations. With built-in version control, logging, and performance metrics, Cloudflare Agents deliver reliable, low-latency responses with secure data handling and seamless scaling.
