Anthropic's SDK for building agents on the Claude Code harness

The Claude Agent SDK gives programmatic access to the same agent loop that powers Claude Code, including file tools, bash execution, custom in-process MCP tools, and hooks for controlling agent behavior. It is MIT-licensed with Python and TypeScript versions; usage requires Claude API access.
