Christian Tzolov 86659344fc feat: add structured logging support with severity levels
- Add client and server-side logging capabilities with configurable severity levels
- Implement logging message notifications with DEBUG to EMERGENCY levels
- Add logging consumers for client-side log handling
- Update documentation with logging examples and configuration
- Add comprehensive tests for logging functionality
- Fix typo in README.md (notificaiotn -> notification)

- Centralize MCP method names as constants
  - Move all JSON-RPC method names to McpSchema class as static constants
  - Replace hardcoded method strings with constant references in McpAsyncClient
    and McpAsyncServer
  - Update test cases to use new method name constants

# 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.
<img src="docs/spring-ai-mcp-architecture.jpg" width="600">
## 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
## Installation
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>
<artifactId>spring-ai-mcp</artifactId>
<version>0.4.0-SNAPSHOT</version>
</dependency>
```
## 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.
