## README

# NOTE: This project has been graduated and moved to the [MCP Java SDK](https://github.com/modelcontextprotocol/java-sdk/tree/main/mcp) and [Spring AI MCP](https://docs.spring.io/spring-ai/reference/api/mcp/mcp-overview.html). See you there! This repository is now archived. 

# Java & Spring MCP
[![Build Status](https://github.com/spring-projects-experimental/spring-ai-mcp/actions/workflows/continuous-integration.yml/badge.svg)](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](https://modelcontextprotocol.org/docs/concepts/architecture). 
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](https://docs.spring.io/spring-ai-mcp/reference/mcp.html)

Java implementation of the Model Context Protocol specification. It includes:
- Synchronous and asynchronous [MCP Client](https://docs.spring.io/spring-ai-mcp/reference/mcp.html#_mcp_client) and [MCP Server](https://docs.spring.io/spring-ai-mcp/reference/mcp.html#_mcp_server) implementations
- Standard MCP operations support (tool discovery, resource management, prompt handling, structured logging). Support for request and notification handling.
- [Stdio](https://spec.modelcontextprotocol.io/specification/2024-11-05/basic/transports/#stdio) and [SSE](https://spec.modelcontextprotocol.io/specification/2024-11-05/basic/transports/#http-with-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](https://github.com/spring-projects-experimental/spring-ai-mcp/tree/main/mcp-transport/mcp-webflux-sse-transport) - Reactive HTTP streaming with Spring WebFlux (Client & Server)
- [WebMvc SSE Transport](https://github.com/spring-projects-experimental/spring-ai-mcp/tree/main/mcp-transport/mcp-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](https://docs.spring.io/spring-ai-mcp/reference/spring-mcp.html)

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)
