The official Java implementation of the Model Context Protocol, developed in collaboration with the Spring AI team. Provides sync and async MCP clients and servers with protocol-complete tool, resource, and prompt handling; integrates naturally with Spring Boot starters for auto-configuration. Completes the official MCP SDK language matrix — TypeScript, Python, Go, Rust, C#, Swift, Kotlin, and now Java.

What it does

  • Java SDK (Java 17+) supporting both synchronous and asynchronous communication patterns
  • Published on Maven Central as io.modelcontextprotocol.sdk:mcp, with a BOM for dependency management
  • Spring AI builds on top: client and server Boot starters plus annotation-based method handling via MCP Annotations
  • Reference docs split into features, architecture, client and server guides on the SDK site

When to use it

The base layer for JVM MCP integrations — Spring Boot teams reach it through Spring AI's starters.
