# Java & Spring MCP
|
|
|
|
Java SDK for the Model Context Protocol (MCP), providing seamless integration between Java and Spring applications and MCP-compliant AI resources and tools.
|
|
|
|
## Overview
|
|
|
|
Provides Java 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.

## Modules
|
|
|
|
The project consists of two main modules:
|
|
|
|
### [mcp](./mcp/README.md)
|
|
|
|
Java implementation of the Model Context Protocol specification. It includes:
|
|
- Synchronous and asynchronous [MCP Client](https://github.com/spring-projects-experimental/spring-ai-mcp/blob/main/mcp/README.md#client-usage-examples) and [MCP Server](https://github.com/spring-projects-experimental/spring-ai-mcp/blob/main/mcp/README.md#server-usage-examples) 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/basic/transports/#stdio) and [SSE](https://spec.modelcontextprotocol.io/specification/basic/transports/#http-with-sse) transport implementations.
|
|
- [Find more](./mcp/README.md).
|
|
|
|
### [spring-ai-mcp](./spring-ai-mcp/README.md)
|
|
|
|
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)
|
|
|
|
## Requirements
|
|
|
|
- Java 17 or later
|
|
- Maven 3.6 or later
|
|
- Spring AI 1.0.0-M4 or later
|
|
|
|

|
Add the following dependencies to your Maven project:
|
|
|
|
```xml
|
|
<!-- For core MCP functionality -->
|
|
<dependency>
|
|
<groupId>org.springframework.experimental</groupId>
|
|
<artifactId>mcp</artifactId>
|
|
<version>0.4.0-SNAPSHOT</version>
|
|
</dependency>
|
|
|
|
<!-- For Spring AI integration -->
|
|
<dependency>
|
|
<groupId>org.springframework.experimental</groupId>
|

|
|
|
## Example Demos
|
|
|
|
Explore these MCP examples in the [spring-ai-examples/model-context-protocol](https://github.com/spring-projects/spring-ai-examples/tree/main/model-context-protocol) repository:
|
|
|
|
- [SQLite Simple](https://github.com/spring-projects/spring-ai-examples/tree/main/model-context-protocol/sqlite/simple) - Demonstrates LLM integration with a database
|
|
- [SQLite Chatbot](https://github.com/spring-projects/spring-ai-examples/tree/main/model-context-protocol/sqlite/chatbot) - Interactive chatbot with SQLite database interaction
|
|
- [Filesystem](https://github.com/spring-projects/spring-ai-examples/tree/main/model-context-protocol/filesystem) - Enables LLM interaction with local filesystem folders and files
|
|
- [Brave](https://github.com/spring-projects/spring-ai-examples/tree/main/model-context-protocol/brave) - Enables natural language interactions with Brave Search, allowing you to perform internet searches.
|
|
- [Spring-ai-mcp-sample](./spring-ai-mcp-sample/) - Showcases how to create and use MCP servers and clients with different transport modes and capabilities.
