## The Hook

Claude Agent SDK is Anthropic’s MIT toolkit to embed the Claude Code-style agent loop — tools, permissions, and sessions — inside your own Python or TypeScript product.

## What's Good

MIT (anthropics/claude-agent-sdk-python ★8,186; TypeScript sibling exists). Programmatic access to agent sessions, built-in tools, permission hooks, and Claude Code–aligned workflows without forking the CLI. Docs at platform.claude.com Agent SDK overview. ★8,186 (Python) on GitHub as of 2026-09-29.

## The Catch

Vs Claude Code (paid terminal product) and OpenAI Agents SDK / Google ADK / Microsoft Agent Framework: this is Anthropic’s first-party embeddable agent runtime, not a multi-provider framework and not the Claude Code subscription UI. You still pay Claude API (or auth) tokens; SDK license is MIT, model usage is not free.

## Verdict

MIT Anthropic Agent SDK when you want Claude Code’s loop inside your app — not the Claude Code Max plan, not a multi-vendor agent framework.
