Anthropic launches Claude Agent SDK for building production AI agents

Anthropic has released the Claude Agent SDK, a TypeScript framework for building production-grade AI agents. The SDK provides tools for multi-step reasoning, tool calling, memory management, and durable execution. Key features include built-in support for MCP (Model Context Protocol) servers, structured output with schema validation, and integration with Claude 4.x models. Early adopters report 60-80% reduction in agent development time compared to building from scratch. The SDK is open source and designed to work with any deployment platform, though it integrates most tightly with Vercel for serverless execution.
