Overview

Claude Agent SDK is a Python and TypeScript library used to build AI agents that can autonomously read files, run commands, search the web, edit code, and more. It provides the same tools, agent loop, and context management found in Claude Code, enabling developers to programmatically create agents that can interact with local file systems or external systems via the Model Context Protocol.

FAQ

What is the primary difference between using the Client SDK and the Agent SDK?+

The Client SDK requires you to implement your own tool loops and execution logic, whereas the Agent SDK provides built-in tool management and an automated agent loop.

Can I integrate existing MCP servers with the Agent SDK?+

Yes, the SDK natively supports connecting to MCP servers, allowing your agents to interact with external databases, browsers, and various APIs.
