Claude Agent SDK

The Claude Agent SDK (Python, TypeScript) transforms Claude into an autonomous, production-ready agent by granting it controlled access to a computer: file operations, Bash execution, and external tool integration via the Model Context Protocol (MCP).

This SDK provides the core agent harness that powers Claude Code, enabling developers to build sophisticated, general-purpose agents. It offers official TypeScript and Python libraries for seamless integration. Agents gain powerful, safe capabilities: reading and writing files, executing sandboxed Bash commands, and leveraging a rich tool ecosystem. The framework includes essential production features (e.g., automatic context management, granular permission modes like `acceptEdits`, and built-in cost tracking). Use the open Model Context Protocol (MCP) to connect custom tools, databases, and APIs, extending Claude’s utility far beyond simple chat to complex, multi-step workflows.
