This page provides instructions for installing the Anthropic Java SDK, setting up a client, and making your first API calls. It covers the essential steps to integrate Claude AI capabilities into your

What began as an experimental project last November has turned into an exciting collaboration with the Spring AI team and Anthropic. We're thrilled to announce that the experimental project has been moved into the official MCP Java SDK. This SDK is the latest language binding of the protocol, alongside the Python, TypeScript, and Kotlin SDKs, on modelcontextprotocol.io.

This guide covers the essentials for contributing to the Anthropic Java SDK. The project uses modern Java development practices with Gradle as the build system and GitHub Actions for CI/CD.

This document covers the core operations for interacting with Claude AI models through the Anthropic Java SDK's Messages API. You'll learn how to create messages, stream responses, and count tokens, w

Learn about Anthropic's APIs, SDKs, and other development tools · Python SDK · TypeScript SDK · Java SDK · Go SDK · Ruby SDK · Understand the Messages API · Process multiple Messages API requests at once with the Message Batches API · Optimize your API usage with prompt caching ·

You can register custom Java Tools with the AnthropicChatModel and have the Anthropic Claude model intelligently choose to output a JSON object containing arguments to call one or many of the registered functions. This is a powerful technique to connect the LLM capabilities with external tools and APIs.

The Anthropic Java SDK provides support for accessing Claude models through Google's Vertex AI platform.

# Add default JVM options here. You can also use JAVA_OPTS and GRADLE_OPTS to pass JVM options to this script.

All batch operations support both synchronous and asynchronous programming models through the Anthropic Java SDK.
