What is the Claude Agent SDK?

It is Anthropic's official library (formerly Claude Code SDK) for building autonomous AI agents that can use tools and perform multi-turn tasks in TypeScript and JavaScript.

How do I handle persistent conversations in the SDK?

You can use the ClaudeSDKClient class for stateful interactions or capture the session_id from a query() response to resume interactions with preserved context.

Can I use this with AWS Bedrock or Google Vertex AI?

Yes, the SDK supports multiple providers via environment variables such as CLAUDE_CODE_USE_BEDROCK, CLAUDE_CODE_USE_VERTEX, or CLAUDE_CODE_USE_FOUNDRY.

How do I create custom tools without a separate server?

The SDK provides a createSdkMcpServer function that allows you to define in-process tools directly within your TypeScript code without needing a standalone MCP process.
