Claude Agent SDK

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.
