- The core module has been refactored to remove unnecessary abstraction between the SSE transport and the STDIO transport. - Tests have been improved and no longer complain about multiple subscriptions to single-subscriber Sink. - SSE transport layer is now assuming non-blocking execution and no longer makes thread hops when not needed. - Decouple ObjectMapper and error handling from AbstractMcpTransport and remove later. Additional improvements: - Rename transport classes to better reflect client-side role (*ServerTransport -> *ClientTransport) - Introduce fluent builder pattern for client configuration - Simplify DefaultMcpSession by removing ObjectMapper dependency - Move unmarshal responsibility to transport layer - Update documentation and diagrams to reflect new architecture - Clean up test implementations

# Spring AI 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
|
|
|
|
Spring AI MCP is an experimental project that 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-core](./spring-ai-mcp-core/README.md)
|
|
|
|
The core module provides a Java implementation of the Model Context Protocol specification. It includes:
|
|
- Synchronous and asynchronous client implementations
|
|
- Standard MCP operations support (tool discovery, resource management, prompt handling). Support for request and notificaiotn 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](./spring-ai-mcp-core/README.md).
|
|
|
|
### [mcp-spring](./spring-ai-mcp-spring/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
|
|

|
|
|
|
