此技能提供了一套基於 LangChain4j 的設計模式與實作範例，專門用於建構遵循模型上下文協定（MCP）的 Java 伺服器。它能協助開發者快速建立可被 AI 代理呼叫的 Java 工具，並將這些工具透過標準化介面暴露給大型語言模型。此外，該技能也涵蓋了 MCP 客戶端的整合方式，讓 LangChain4j 應用程式能夠連結外部 MCP 伺服器，以擴展 AI 服務的工具呼叫能力。對於需要為代理工作流程實作安全工具暴露的 Java 開發者而言，這是一套不可或缺的參考資源，支援如 Claude Code、Cursor 等主流平台。

Use when setting up RDS connections in Spring Boot, configuring connection pooling, or managing database credentials securely.
Provides Amazon Bedrock patterns using AWS SDK for Java 2.x. Invokes foundation models (Claude, Llama, Titan), generates text and images, creates embeddings for RAG, streams real-time responses, and configures Spring Boot integration. Use when asking about Bedrock integration, Java SDK for AI models, AWS generative AI, Claude/Llama invocation, embeddings for RAG, or Spring Boot AI setup.
Provides AWS SDK for Java 2.x client configuration, credential resolution, HTTP client tuning, timeout, retry, and testing patterns. Use when creating or hardening AWS service clients, wiring Spring Boot beans, debugging auth or region issues, or choosing sync vs async SDK usage.
Provides Amazon DynamoDB patterns using AWS SDK for Java 2.x. Use when creating, querying, scanning, or performing CRUD operations on DynamoDB tables, working with indexes, batch operations, transactions, or integrating with Spring Boot applications.
Provides AWS Key Management Service (KMS) patterns using AWS SDK for Java 2.x. Use when creating/managing encryption keys, encrypting/decrypting data, generating data keys, digital signing, key rotation, or integrating encryption into Spring Boot applications.
