Spring Ai Mcp

NOTE: This project has been graduated and moved to the MCP Java SDK and Spring AI MCP. See you there! This repository is now archived.

Java & Spring MCP

[](https://github.com/spring-projects-experimental/spring-ai-mcp/actions/workflows/continuous-integration.yml)

Set of projects that provide Java SDK and Spring Framework integration for the Model Context Protocol. It enables Java applications to interact with AI models and tools through a standardized interface, supporting both synchronous and asynchronous communication patterns.

Projects

MCP Java SDK

Java implementation of the Model Context Protocol specification. It includes:

• Synchronous and asynchronous MCP Client and MCP Server implementations
• Standard MCP operations support (tool discovery, resource management, prompt handling, structured logging). Support for request and notification handling.
• Stdio and SSE transport implementations.

MCP Transports

Core Transports

• Stdio-based (StdioClientTransport, StdioServerTransport) for process-based communication
• Java HttpClient-based SSE client (HttpClientSseClientTransport) for HTTP streaming
• Servlet-based SSE server (HttpServletSseServerTransport) for HTTP SSE Server streaming using traditional Servlet API

Optional SSE Transports

• WebFlux SSE Transport - Reactive HTTP streaming with Spring WebFlux (Client & Server)
• WebMvc SSE Transport - Spring MVC based HTTP SSE transport (Server only).

You can use the core HttpClientSseClientTransport transport as a SSE client.

Spring AI MCP

The Spring integration module provides Spring-specific functionality:

• Integration with Spring AI's function calling system
• Spring-friendly abstractions for MCP clients
• Auto-configurations (WIP)

Installation

Add the following dependencies to your Maven project:

    org.springframework.experimental
    mcp

    org.springframework.experimental
    mcp-webflux-sse-transport

    org.springframework.experimental
    mcp-webmvc-sse-transport

    org.springframework.experimental
    spring-ai-mcp

This is a milestone release, not available on Maven Central. Add this repository to your POM:
