About

Claude Agent SDK packages the agent loop and tools behind Claude Code as a programmable library for Python and TypeScript. It lets developers build agents that can inspect files, run commands, search the web, edit code, and coordinate custom tools without implementing the execution loop from scratch.

Key features

Built-in file, shell, web, and code-editing tools
Python and TypeScript packages
Context management and autonomous tool execution
Custom tools through in-process MCP servers
Support for Anthropic API, Amazon Bedrock, Google Vertex AI, and Microsoft Azure

It is designed for production agents that need to take concrete actions in a controlled computing environment.
