Can I use Model Context Protocol (MCP) with this skill?

Absolutely. The SDK includes native support for connecting to both in-process and external MCP servers via stdio, HTTP, or SSE transports.

What happens to subagents when a parent agent stops?

Currently, subagents may continue running as orphaned processes; it is recommended to use the 'Stop' hook to implement manual cleanup and process termination.

What is the primary benefit of the Claude Agent SDK?

The SDK provides a standardized framework for building autonomous agents with guaranteed JSON output validation and a robust hooks system for granular event handling.

Does this SDK support Zod for schema validation?

Yes, the SDK is fully compatible with Zod v3 and v4, allowing for seamless TypeScript inference and strict runtime validation of agent responses.

How do hooks improve agent behavior?

The 12 available hooks allow developers to intercept, modify, or block tool calls, manage session state, and implement custom approval workflows for sensitive operations.

Developer Tools

Builds production-ready autonomous AI agents with strictly validated structured outputs and event-driven workflows.

The Claude Agent SDK is a comprehensive framework designed for developers to create sophisticated, autonomous AI agents capable of handling complex coding, SRE, and security auditing tasks. By leveraging structured outputs via JSON schema and Zod, it guarantees type-safe responses and eliminates common validation errors that plague autonomous systems. The SDK's robust hooks system allows for deep integration into event-driven workflows—offering 12 distinct event triggers—while built-in support for MCP servers and subagent orchestration enables the creation of highly scalable, modular, and reliable AI systems.
