# Spring AI Model Context Protocol (MCP) Examples
|
||||
|
||||
This directory contains various examples demonstrating the usage of Spring AI's Model Context Protocol (MCP). Each example showcases different aspects of MCP implementation, including various transport methods and client-server configurations.
|
||||
|
||||
|
||||
## Transport Types
|
||||
|
||||
The examples demonstrate two main types of transport:
|
||||
|
||||
1. **STDIO Transport**
|
||||
- Process-based communication
|
||||
- Synchronous communication
|
||||
- Used in all client examples
|
||||
- Available in all server implementations
|
||||
|
||||
2. **HTTP SSE (Server-Sent Events) Transport**
|
||||
- HTTP-based streaming communication
|
||||
- Asynchronous communication
|
||||
- Available in server implementations
|
||||
- Implemented in three variants:
|
||||
- Servlet-based (Spring MVC)
|
||||
- WebFlux-based (Reactive)
|
||||
- WebMVC-based
|
||||
|
||||
## API Types
|
||||
|
||||
The examples demonstrate both synchronous and asynchronous API usage:
|
||||
|
||||
- **Synchronous API**: Used in STDIO transport implementations
|
||||
- **Asynchronous API**: Used in SSE transport implementations
|
||||
|
||||
## Getting Started
|
||||
|
||||
Each example project can be built using Maven:
|
||||
|
||||
```bash
|
||||
./mvnw clean install
|
||||
```
|
||||
|
||||
For running the examples:
|
||||
1. For STDIO transport: Run the client application directly
|
||||
2. For SSE transport: Start the server first, then run the client
|
||||
|
||||
## Note
|
||||
|
||||
- All server implementations support both STDIO and SSE transport modes
|
||||
- Transport mode can be configured using the `transport.mode` property
|
||||
- Client examples primarily use STDIO transport for simplicity
|
||||
- Server starters provide auto-configuration support for easier integration
|
||||

# Spring AI - Model Context Protocol (MCP) Brave Search Chatbot
|
||||
|
||||
This example demonstrates how to build an interactive chatbot that combines Spring AI's Model Context Protocol (MCP) with the [Brave Search MCP Server](https://github.com/modelcontextprotocol/servers/tree/main/src/brave-search). The application creates a conversational interface powered by Anthropic's Claude AI model that can perform internet searches through Brave Search, enabling natural language interactions with real-time web data.
|
||||
|
||||
<img src="spring-ai-mcp-brave.jpg" width="600"/>
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Java 17 or higher
|
||||
- Maven 3.6+
|
||||
- npx package manager
|
||||
- Anthropic API key (Claude)
|
||||
- Brave Search API key (Get one at https://brave.com/search/api/)
|
||||
|
||||
## Setup
|
||||
|
||||
1. Install npx (Node Package eXecute):
|
||||
First, make sure to install [npm](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm)
|
||||
and then run:
|
||||
```bash
|
||||
npm install -g npx
|
||||
```
|
||||
|
||||
2. Clone the repository:
|
||||
```bash
|
||||
git clone https://github.com/spring-projects/spring-ai-examples.git
|
||||
cd model-context-protocol/brave-chatbot
|
||||
```
|
||||
|
||||
3. Set up your API keys:
|
||||
```bash
|
||||
export ANTHROPIC_API_KEY='your-anthropic-api-key-here'
|
||||
export BRAVE_API_KEY='your-brave-api-key-here'
|
||||
```
|
||||
|
||||
4. Build the application:
|
||||
```bash
|
||||
./mvnw clean install
|
||||
```
|
||||
|
||||
## Running the Application
|
||||
|
||||
Run the application using Maven:
|
||||
```bash
|
||||
./mvnw spring-boot:run
|
||||
```
|
||||
|
||||
The application will start an interactive chat session where you can ask questions. The chatbot will use Brave Search when it needs to find information from the internet to answer your queries.
|
||||
|
||||
## How it Works
|
||||
|
||||
The application integrates Spring AI with the Brave Search MCP server through several components:
|
||||
|
||||
### MCP Client Configuration
|
||||
|
||||
1. Required dependencies in pom.xml:
|
||||
```xml
|
||||
<dependency>
|
||||
<groupId>org.springframework.ai</groupId>
|
||||
<artifactId>spring-ai-mcp-spring-boot-starter</artifactId>
|
||||
</dependency>
|
||||
<dependency>
|
||||
<groupId>org.springframework.ai</groupId>
|
||||
<artifactId>spring-ai-anthropic-spring-boot-starter</artifactId>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
2. Application properties (application.properties):
|
||||
```properties
|
||||
spring.ai.mcp.client.stdio.enabled=true
|
||||
spring.ai.mcp.client.stdio.servers-configuration=classpath:/mcp-servers-config.json
|
||||
spring.ai.anthropic.api-key=${ANTHROPIC_API_KEY}
|
||||
```
|
||||
|
||||
3. MCP Server Configuration (mcp-servers-config.json):
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"brave-search": {
|
||||
"command": "npx",
|
||||
"args": [
|
||||
"-y",
|
||||
"@modelcontextprotocol/server-brave-search"
|
||||
],
|
||||
"env": {
|
||||
"BRAVE_API_KEY": "${BRAVE_API_KEY}"
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Chat Implementation
|
||||
|
||||
The chatbot is implemented using Spring AI's ChatClient with MCP tool integration:
|
||||
|
||||
```java
|
||||
var chatClient = chatClientBuilder
|
||||
.defaultSystem("You are a useful assistant, expert in AI and Java.")
|
||||
.defaultTools((Object[]) mcpToolAdapter.toolCallbacks())
|
||||
.defaultAdvisors(new MessageChatMemoryAdvisor(new InMemoryChatMemory()))
|
||||
.build();
|
||||
```
|
||||
|
||||
Key features:
|
||||
- Uses Claude AI model for natural language understanding
|
||||
- Integrates Brave Search through MCP for real-time web search capabilities
|
||||
- Maintains conversation memory using InMemoryChatMemory
|
||||
- Runs as an interactive command-line application
|
||||
|
||||
The chatbot can:
|
||||
- Answer questions using its built-in knowledge
|
||||
- Perform web searches when needed using Brave Search
|
||||
- Remember context from previous messages in the conversation
|
||||
- Combine information from multiple sources to provide comprehensive answers

# Spring AI - Model Context Protocol (MCP) Brave Search Example
|
||||
|
||||
This example demonstrates how to use the Spring AI Model Context Protocol (MCP) with the [Brave Search MCP Server](https://github.com/modelcontextprotocol/servers/tree/main/src/brave-search). The application enables natural language interactions with Brave Search, allowing you to perform internet searches through a conversational interface.
|
||||
|
||||
<img src="spring-ai-mcp-brave.jpg" width="600"/>
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Java 17 or higher
|
||||
- Maven 3.6+
|
||||
- npx package manager
|
||||
- OpenAI API key
|
||||
- Brave Search API key (Get one at https://brave.com/search/api/)
|
||||
|
||||
## Setup
|
||||
|
||||
1. Install npx (Node Package eXecute):
|
||||
First, make sure to install [npm](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm)
|
||||
and then run:
|
||||
```bash
|
||||
npm install -g npx
|
||||
```
|
||||
|
||||
2. Clone the repository:
|
||||
```bash
|
||||
git clone https://github.com/spring-projects/spring-ai-examples.git
|
||||
cd model-context-protocol/brave-starter
|
||||
```
|
||||
|
||||
3. Set up your API keys:
|
||||
```bash
|
||||
export OPENAI_API_KEY='your-openai-api-key-here'
|
||||
export BRAVE_API_KEY='your-brave-api-key-here'
|
||||
```
|
||||
|
||||
4. Build the application:
|
||||
```bash
|
||||
./mvnw clean install
|
||||
```
|
||||
|
||||
## Running the Application
|
||||
|
||||
Run the application using Maven:
|
||||
```bash
|
||||
./mvnw spring-boot:run
|
||||
```
|
||||
|
||||
The application will demonstrate the integration by asking a sample question about Spring AI and Model Context Protocol, utilizing Brave Search to gather information.
|
||||
|
||||
## How it Works
|
||||
|
||||
The application demonstrates Spring AI integration with Brave Search through the Model Context Protocol (MCP). Here's an overview of the key components:
|
||||
|
||||
### Project Configuration
|
||||
|
||||
The project uses Spring AI's MCP boot starter:
|
||||
|
||||
```xml
|
||||
<dependency>
|
||||
<groupId>org.springframework.ai</groupId>
|
||||
<artifactId>spring-ai-mcp-spring-boot-starter</artifactId>
|
||||
</dependency>
|
||||
```
|
||||
|
||||
The application configuration is defined in two files:
|
||||
|
||||
1. `application.properties` - Core application settings:
|
||||
```properties
|
||||
# Application configuration
|
||||
spring.application.name=mcp
|
||||
spring.main.web-application-type=none
|
||||
|
||||
# API Keys
|
||||
spring.ai.openai.api-key=${OPENAI_API_KEY}
|
||||
|
||||
|
||||
# MCP Configuration
|
||||
spring.ai.mcp.client.stdio.enabled=true
|
||||
spring.ai.mcp.client.stdio.servers-configuration=classpath:/mcp-servers-config.json
|
||||
```
|
||||
|
||||
2. `mcp-servers-config.json` - MCP server configuration:
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"brave-search": {
|
||||
"command": "npx",
|
||||
"args": [
|
||||
"-y",
|
||||
"@modelcontextprotocol/server-brave-search"
|
||||
],
|
||||
"env": {
|
||||
}
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Auto-Configuration
|
||||
|
||||
Spring Boot's auto-configuration handles the setup:
|
||||
- Configures the application as a command-line tool (non-web)
|
||||
- Sets up the OpenAI integration using the provided API key
|
||||
- Enables the MCP STDIO client for communication with the Brave Search server
|
||||
- Provides a `List<ToolCallback>` bean containing the Brave Search capabilities, which is automatically injected into the `CommandLineRunner`
|
||||
|
||||
### Main Application
|
||||
|
||||
The `Application.java` file demonstrates a simple Spring Boot application that:
|
||||
|
||||
1. Uses Spring Boot's `CommandLineRunner` to execute a predefined question when the application starts
|
||||
2. Creates a `ChatClient` with the automatically configured MCP tools (Brave Search capabilities)
|
||||
3. Asks a specific question about Spring AI and Model Context Protocol
|
||||
4. Prints both the question and the AI assistant's response to the console
|
||||
5. Automatically closes the application after receiving the response
|
||||
|
||||
Here's the key code from `Application.java`:
|
||||
|
||||
```java
|
||||
@Bean
|
||||
public CommandLineRunner predefinedQuestions(ChatClient.Builder chatClientBuilder,
|
||||
List<ToolCallback> tools, ConfigurableApplicationContext context) {
|
||||
return args -> {
|
||||
var chatClient = chatClientBuilder
|
||||
.defaultTools(tools)
|
||||
.build();
|
||||
|
||||
String question = "Does Spring AI support the Model Context Protocol? "
|
||||
+ "Please provide some references.";
|
||||
|
||||
System.out.println("QUESTION: " + question);
|
||||
System.out.println("ASSISTANT: " + chatClient.prompt(question).call().content());
|
||||
|
||||
context.close();
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
The application automatically:
|
||||
- Injects the `ChatClient.Builder` and `ToolCallback` list (containing Brave Search capabilities)
|
||||
- Configures the chat client with the available tools
|
||||
- Executes a predefined question
|
||||
- Uses Brave Search when needed to gather information for the response
|
||||
|
||||
This setup allows the AI model to do the following:
|
||||
- Understand when to use Brave Search
|
||||
- Format queries appropriately
|
||||
- Process and incorporate search results into responses

# Spring AI MCP Quick Weather Server Sample
|
||||
|
||||
This sample project demonstrates a simplified implementation of the Spring AI Model Context Protocol (MCP). It shows how to create an MCP server that exposes weather-related tools using the National Weather Service API.
|
||||
|
||||
## Overview
|
||||
|
||||
The sample provides:
|
||||
- A Spring Boot application implementing an MCP server
|
||||
- Two transport mode implementations: Stdio and SSE (Server-Sent Events)
|
||||
- Two weather-related tools:
|
||||
- Get weather forecast by location (latitude/longitude)
|
||||
- Get weather alerts by US state
|
||||
|
||||
## Building the Project
|
||||
|
||||
```bash
|
||||
./mvnw clean package
|
||||
```
|
||||
|
||||
## Running the Server
|
||||
|
||||
The server can be started in two transport modes, controlled by the `transport.mode` property:
|
||||
|
||||
### Stdio Mode (Default)
|
||||
|
||||
```bash
|
||||
java -Dspring.ai.mcp.server.transport=STDIO -Dspring.main.web-application-type=none -Dlogging.pattern.console= -jar target/mcp-weather-server-quick-0.0.1-SNAPSHOT.jar
|
||||
```
|
||||
|
||||
The Stdio mode server is automatically started by the client - no explicit server startup is needed.
|
||||
But you have to build the server jar first: `./mvnw clean install -DskipTests`.
|
||||
|
||||
In Stdio mode the server must not emit any messages/logs to the console (e.g. standard out) but the JSON messages produced by the server.
|
||||
|
||||
### SSE Mode
|
||||
```bash
|
||||
java -Dspring.ai.mcp.server.transport=WEBFLUX -jar target/mcp-weather-server-quick-0.0.1-SNAPSHOT.jar
|
||||
```
|
||||
|
||||
## Sample Clients
|
||||
|
||||
The project includes example clients for both transport modes:
|
||||
|
||||
### Stdio Client (ClientStdio.java)
|
||||
```java
|
||||
var stdioParams = ServerParameters.builder("java")
|
||||
.args("-Dspring.ai.mcp.server.transport=STDIO", "-Dspring.main.web-application-type=none",
|
||||
"-Dlogging.pattern.console=", "-jar",
|
||||
"model-context-protocol/mcp-weather-server-quick/target/mcp-weather-server-quick-0.0.1-SNAPSHOT.jar")
|
||||
.build();
|
||||
|
||||
var transport = new StdioClientTransport(stdioParams);
|
||||
var client = McpClient.sync(transport).build();
|
||||
```
|
||||
|
||||
### SSE Client (ClientSse.java)
|
||||
```java
|
||||
var transport = new WebFluxSseClientTransport(WebClient.builder().baseUrl("http://localhost:8080"));
|
||||
var client = McpClient.using(transport).sync();
|
||||
```
|
||||
|
||||
### Claud Destop
|
||||
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"spring-ai-mcp-weather": {
|
||||
"command": "java",
|
||||
"args": [
|
||||
"-Dspring.ai.mcp.server.transport=STDIO",
|
||||
"-Dspring.main.web-application-type=none",
|
||||
"-Dlogging.pattern.console=",
|
||||
"-jar",
|
||||
"<YOUR ABSOLUTE PATH TO>/mcp-weather-server-quick-0.0.1-SNAPSHOT.jar"
|
||||
]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Available Tools
|
||||
|
||||
### Weather Forecast Tool
|
||||
- Name: `getWeatherForecastByLocation`
|
||||
- Description: Get weather forecast for a specific latitude/longitude
|
||||
- Parameters:
|
||||
- `latitude`: double - Latitude coordinate
|
||||
- `longitude`: double - Longitude coordinate
|
||||
- Example:
|
||||
```java
|
||||
CallToolResult forecastResult = client.callTool(new CallToolRequest("getWeatherForecastByLocation",
|
||||
Map.of("latitude", 47.6062, "longitude", -122.3321)));
|
||||
```
|
||||
|
||||
### Weather Alerts Tool
|
||||
- Name: `getAlerts`
|
||||
- Description: Get weather alerts for a US state
|
||||
- Parameters:
|
||||
- `state`: String - Two-letter US state code (e.g. CA, NY)
|
||||
- Example:
|
||||
```java
|
||||
CallToolResult alertResult = client.callTool(new CallToolRequest("getAlerts",
|
||||
Map.of("state", "NY")));
|
||||
```
|
||||
|
||||
## Client Usage Example
|
||||
|
||||
```java
|
||||
// Initialize client
|
||||
client.initialize();
|
||||
|
||||
// Test connection
|
||||
client.ping();
|
||||
|
||||
// List available tools
|
||||
ListToolsResult tools = client.listTools();
|
||||
System.out.println("Available tools: " + tools);
|
||||
|
||||
// Get weather forecast for Seattle
|
||||
CallToolResult weatherForcastResult = client.callTool(new CallToolRequest("getWeatherForecastByLocation",
|
||||
Map.of("latitude", "47.6062", "longitude", "-122.3321")));
|
||||
System.out.println("Weather Forcast: " + weatherForcastResult);
|
||||
|
||||
// Get weather alerts for New York
|
||||
CallToolResult alertResult = client.callTool(new CallToolRequest("getAlerts", Map.of("state", "NY")));
|
||||
System.out.println("Alert Response = " + alertResult);
|
||||
|
||||
// Close client
|
||||
client.closeGracefully();
|
||||
```
|
||||
|
||||
## Server Implementation
|
||||
|
||||
The server is implemented using Spring Boot and Spring AI's tool annotations:
|
||||
|
||||
```java
|
||||
@SpringBootApplication
|
||||
public class McpServerApplication {
|
||||
|
||||
public static void main(String[] args) {
|
||||
SpringApplication.run(McpServerApplication.class, args);
|
||||
}
|
||||
|
||||
@Bean
|
||||
public List<ToolCallback> weatherTools(WeatherService weatherService) {
|
||||
return List.of(ToolCallbacks.from(weatherService));
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The `WeatherService` class provides the tool implementations using the `@Tool` annotation:
|
||||
|
||||
```java
|
||||
@Service
|
||||
public class WeatherService {
|
||||
@Tool(description = "Get weather forecast for a specific latitude/longitude")
|
||||
public String getWeatherForecastByLocation(double latitude, double longitude) {
|
||||
// Implementation using weather.gov API
|
||||
}
|
||||
|
||||
@Tool(description = "Get weather alerts for a US state. Input is Two-letter US state code (e.g. CA, NY)")
|
||||
public String getAlerts(String state) {
|
||||
// Implementation using weather.gov API
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
The application can be configured through `application.properties`:
|
||||
|
||||
- `spring.ai.mcp.server.transport`: Transport mode to use (STDIO/WEBFLUX)
|
||||
- `server.port`: Server port for WEBFLUX mode (default: 8080)
|
||||
- `spring.main.banner-mode`: Set to 'off' for STDIO mode
|
||||
- `logging.pattern.console`: Clear this property for STDIO mode
|
||||
- `logging.file.name`: Path to log file (useful when console logging is disabled)

# Spring AI MCP Quick Weather Server Sample
|
||||
|
||||
This sample project demonstrates a simplified implementation of the Spring AI Model Context Protocol (MCP). It shows how to create an MCP server that exposes weather-related tools using the National Weather Service API.
|
||||
|
||||
## Overview
|
||||
|
||||
The sample provides:
|
||||
- A Spring Boot application implementing an MCP server
|
||||
- Two transport mode implementations: Stdio and SSE (Server-Sent Events)
|
||||
- Two weather-related tools:
|
||||
- Get weather forecast by location (latitude/longitude)
|
||||
- Get weather alerts by US state
|
||||
|
||||
## Building the Project
|
||||
|
||||
```bash
|
||||
./mvnw clean install -DskipTests
|
||||
```
|
||||
|
||||
## Running the Server
|
||||
|
||||
The server can be started in two transport modes, controlled by the `transport.mode` property:
|
||||
|
||||
### Stdio Mode (Default)
|
||||
|
||||
The Stdio mode server is automatically started by the client - no explicit server startup is needed.
|
||||
But you have to build the server jar first: `./mvnw clean install -DskipTests`.
|
||||
|
||||
In Stdio mode the server must not emit any messages/logs to the console (e.g. standard out) but the JSON messages produced by the server.
|
||||
|
||||
### SSE Mode
|
||||
```bash
|
||||
java -Dspring.ai.mcp.server.transport=WEBFLUX -jar target/mcp-weather-server-quick-0.0.1-SNAPSHOT.jar
|
||||
```
|
||||
|
||||
## Sample Clients
|
||||
|
||||
The project includes example clients for both transport modes:
|
||||
|
||||
### Stdio Client (ClientStdio.java)
|
||||
|
||||
**Note:** When running via command line, you may need to specify the full path to your Java executable since the shell environment (including `.bashrc`) might not be loaded. For example, instead of `"java"`, you might need to use the full path like `"/home/user/.sdkman/candidates/java/current/bin/java"`. You can find your Java path by running `which java` in your terminal.
|
||||
|
||||
```java
|
||||
var stdioParams = ServerParameters.builder("java") // You may need to use full path to Java executable
|
||||
.args("-Dspring.ai.mcp.server.transport=STDIO", "-Dspring.main.web-application-type=none",
|
||||
"-Dlogging.pattern.console=", "-jar",
|
||||
"model-context-protocol/mcp-weather-server-quick/target/mcp-weather-server-quick-0.0.1-SNAPSHOT.jar")
|
||||
.build();
|
||||
|
||||
var transport = new StdioClientTransport(stdioParams);
|
||||
var client = McpClient.sync(transport).build();
|
||||
```
|
||||
|
||||
### SSE Client (ClientSse.java)
|
||||
```java
|
||||
var transport = new WebFluxSseClientTransport(WebClient.builder().baseUrl("http://localhost:8080"));
|
||||
var client = McpClient.using(transport).sync();
|
||||
```
|
||||
|
||||
### Claude Desktop
|
||||
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"spring-ai-mcp-weather": {
|
||||
"command": "java",
|
||||
"args": [
|
||||
"-Dspring.ai.mcp.server.transport=STDIO",
|
||||
"-Dspring.main.web-application-type=none",
|
||||
"-Dlogging.pattern.console=",
|
||||
"-jar",
|
||||
"<YOUR ABSOLUTE PATH TO>/mcp-weather-server-quick-0.0.1-SNAPSHOT.jar"
|
||||
]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Available Tools
|
||||
|
||||
### Weather Forecast Tool
|
||||
- Name: `getWeatherForecastByLocation`
|
||||
- Description: Get weather forecast for a specific latitude/longitude
|
||||
- Parameters:
|
||||
- `latitude`: double - Latitude coordinate
|
||||
- `longitude`: double - Longitude coordinate
|
||||
- Example:
|
||||
```java
|
||||
CallToolResult forecastResult = client.callTool(new CallToolRequest("getWeatherForecastByLocation",
|
||||
Map.of("latitude", 47.6062, "longitude", -122.3321)));
|
||||
```
|
||||
|
||||
### Weather Alerts Tool
|
||||
- Name: `getAlerts`
|
||||
- Description: Get weather alerts for a US state
|
||||
- Parameters:
|
||||
- `state`: String - Two-letter US state code (e.g. CA, NY)
|
||||
- Example:
|
||||
```java
|
||||
CallToolResult alertResult = client.callTool(new CallToolRequest("getAlerts",
|
||||
Map.of("state", "NY")));
|
||||
```
|
||||
|
||||
## Client Usage Example (SampleClient.java)
|
||||
|
||||
```java
|
||||
// Initialize client
|
||||
client.initialize();
|
||||
|
||||
// Test connection
|
||||
client.ping();
|
||||
|
||||
// List available tools
|
||||
ListToolsResult tools = client.listTools();
|
||||
System.out.println("Available tools: " + tools);
|
||||
|
||||
// Get weather forecast for Seattle
|
||||
CallToolResult weatherForcastResult = client.callTool(new CallToolRequest("getWeatherForecastByLocation",
|
||||
Map.of("latitude", "47.6062", "longitude", "-122.3321")));
|
||||
System.out.println("Weather Forcast: " + weatherForcastResult);
|
||||
|
||||
// Get weather alerts for New York
|
||||
CallToolResult alertResult = client.callTool(new CallToolRequest("getAlerts", Map.of("state", "NY")));
|
||||
System.out.println("Alert Response = " + alertResult);
|
||||
|
||||
// Close client
|
||||
client.closeGracefully();
|
||||
```
|
||||
|
||||
## Server Implementation
|
||||
|
||||
The server is implemented using Spring Boot and Spring AI's tool annotations:
|
||||
|
||||
```java
|
||||
@SpringBootApplication
|
||||
public class McpServerApplication {
|
||||
|
||||
public static void main(String[] args) {
|
||||
SpringApplication.run(McpServerApplication.class, args);
|
||||
}
|
||||
|
||||
@Bean
|
||||
public List<ToolCallback> weatherTools(WeatherService weatherService) {
|
||||
return List.of(ToolCallbacks.from(weatherService));
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The `WeatherService` class provides the tool implementations using the `@Tool` annotation:
|
||||
|
||||
```java
|
||||
@Service
|
||||
public class WeatherService {
|
||||
@Tool(description = "Get weather forecast for a specific latitude/longitude")
|
||||
public String getWeatherForecastByLocation(double latitude, double longitude) {
|
||||
// Implementation using weather.gov API
|
||||
}
|
||||
|
||||
@Tool(description = "Get weather alerts for a US state. Input is Two-letter US state code (e.g. CA, NY)")
|
||||
public String getAlerts(String state) {
|
||||
// Implementation using weather.gov API
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
The application can be configured through `application.properties`:
|
||||
|
||||
- `spring.ai.mcp.server.transport`: Transport mode to use (STDIO/WEBFLUX)
|
||||
- `server.port`: Server port for WEBFLUX mode (default: 8080)
|
||||
- `spring.main.banner-mode`: Set to 'off' for STDIO mode
|
||||
- `logging.pattern.console`: Clear this property for STDIO mode
|
||||
- `logging.file.name`: Path to log file (useful when console logging is disabled)

# Spring AI MCP Sample Weather MCP Server
|
||||
|
||||
This sample project demonstrates the usage of the Spring AI Model Context Protocol (MCP) implementation. It showcases how to create and use MCP servers and clients with different transport modes and capabilities.
|
||||
|
||||
## Overview
|
||||
|
||||
The sample provides:
|
||||
- Two transport mode implementations: Stdio and SSE (Server-Sent Events)
|
||||
- Server capabilities:
|
||||
- Tools support with list changes notifications
|
||||
- Resources support with list changes notifications (no subscribe support)
|
||||
- Prompts support with list changes notifications
|
||||
- Sample implementations:
|
||||
- Two MCP tools: Weather and Calculator
|
||||
- One MCP resource: System Information
|
||||
- One MCP prompt: Greeting
|
||||
|
||||
## Building the Project
|
||||
|
||||
```bash
|
||||
./mvnw clean package
|
||||
```
|
||||
|
||||
## Running the Server
|
||||
|
||||
The server can be started in two transport modes, controlled by the `transport.mode` property:
|
||||
|
||||
### Stdio Mode (Default)
|
||||
|
||||
```bash
|
||||
java -Dtransport.mode=stdio -jar model-context-protocol/mcp-weather-server/target/mcp-weather-server-0.0.1-SNAPSHOT.jar
|
||||
```
|
||||
|
||||
The Stdio mode server is automatically started by the client - no explicit server startup is needed.
|
||||
But you have to build the server jar first: `./mvnw clean install -DskipTests`.
|
||||
|
||||
In Stdio mode the server must not emit any messages/logs to the console (e.g. standard out) but the JSON messages produced by the server.
|
||||
|
||||
### SSE Mode
|
||||
```bash
|
||||
java -Dtransport.mode=sse -jar model-context-protocol/mcp-weather-server/target/mcp-weather-server-0.0.1-SNAPSHOT.jar
|
||||
```
|
||||
|
||||
## Sample Clients
|
||||
|
||||
The project includes example clients for both transport modes:
|
||||
|
||||
### Stdio Client (ClientStdio.java)
|
||||
```java
|
||||
var stdioParams = ServerParameters.builder("java")
|
||||
.args("-Dtransport.mode=stdio", "-Dspring.main.web-application-type=none", "-jar",
|
||||
"model-context-protocol/mcp-weather-server/target/mcp-weather-server-0.0.1-SNAPSHOT.jar")
|
||||
.build();
|
||||
|
||||
var transport = new StdioClientTransport(stdioParams);
|
||||
var client = McpClient.using(transport).sync();
|
||||
```
|
||||
|
||||
### SSE Client (ClientWebFluxSse.java)
|
||||
```java
|
||||
var transport = new SseClientTransport(WebClient.builder().baseUrl("http://localhost:8080"));
|
||||
var client = McpClient.using(transport).sync();
|
||||
```
|
||||
|
||||
## Available Tools
|
||||
|
||||
### Weather Tool
|
||||
- Name: `getWeatherForecastByLocation`
|
||||
- Description: Weather forecast tool by location
|
||||
- Parameters:
|
||||
- `lat, long`: String - latitude, longitude of the locaiton
|
||||
- Example:
|
||||
```java
|
||||
CallToolResult weatherForcastResult = client.callTool(new CallToolRequest("getWeatherForecastByLocation",
|
||||
Map.of("latitude", "47.6062", "longitude", "-122.3321")));
|
||||
```
|
||||
|
||||
|
||||
## Client Usage Example
|
||||
|
||||
```java
|
||||
// Initialize client
|
||||
client.initialize();
|
||||
|
||||
// Test connection
|
||||
client.ping();
|
||||
|
||||
// List available tools
|
||||
ListToolsResult tools = client.listTools();
|
||||
System.out.println("Available tools: " + tools);
|
||||
|
||||
CallToolResult weatherForcastResult = client.callTool(new CallToolRequest("getWeatherForecastByLocation",
|
||||
Map.of("latitude", "47.6062", "longitude", "-122.3321")));
|
||||
System.out.println("Weather Forcast: " + weatherForcastResult);
|
||||
|
||||
CallToolResult alertResult = client.callTool(new CallToolRequest("getAlerts", Map.of("state", "NY")));
|
||||
System.out.println("Alert Response = " + alertResult);
|
||||
|
||||
|
||||
// Close client
|
||||
client.closeGracefully();
|
||||
```
|
||||
|
||||
## Server Usage Example
|
||||
|
||||
```java
|
||||
@Configuration
|
||||
public class CustomMcpServerConfig {
|
||||
|
||||
@Bean
|
||||
public WeatherApiClient weatherApiClient() {
|
||||
return new WeatherApiClient();
|
||||
}
|
||||
|
||||
@Bean
|
||||
public McpSyncServer mcpServer(ServerMcpTransport transport, WeatherApiClient weatherApiClient) { // @formatter:off
|
||||
|
||||
// Configure server capabilities with resource support
|
||||
var capabilities = McpSchema.ServerCapabilities.builder()
|
||||
.tools(true) // Tool support with list changes notifications
|
||||
.logging() // Logging support
|
||||
.build();
|
||||
|
||||
// Create the server with both tool and resource capabilities
|

|
||||
|
||||
This project demonstrates how to create a Spring AI Model Context Protocol (MCP) server using Spring WebFlux. It showcases how to implement MCP tools, resources, and prompts with Spring Boot's auto-configuration capabilities.
|
||||
|
||||
## Overview
|
||||
|
||||
The project provides:
|
||||
- Spring Boot starter for MCP server implementation
|
||||
- WebFlux-based transport mode
|
||||
- Server capabilities:
|
||||
- Tools support with OpenLibrary integration
|
||||
- Resources support with system information
|
||||

```
|
||||
|
||||
## Running the Server
|
||||
|
||||
The server uses WebFlux transport mode by default:
|
||||
|
||||
```bash
|
||||
java -jar target/mcp-webflux-server-starter-0.0.1-SNAPSHOT.jar
|
||||
```
|
||||
|
||||
## Available Tools
|
||||
|
||||

|
||||
- Parameters:
|
||||
- `title`: String - The book title to search for
|
||||
- Example:
|
||||
```java
|
||||
CallToolResult response = client.callTool(
|
||||
new CallToolRequest("getBooks", Map.of("title", "Spring Framework"))
|
||||
);
|
||||
```
|
||||
|
||||
#### Get Book Titles by Author
|
||||
- Description: Get book titles by author
|
||||
- Parameters:
|
||||
- `authorName`: String - The author name to search for
|
||||

||||
```java
|
||||
CallToolResult response = client.callTool(
|
||||
new CallToolRequest("getBookTitlesByAuthor", Map.of("authorName", "Craig Walls"))
|
||||
);
|
||||
```
|
||||
|
||||
### Text Processing Tool
|
||||
#### toUpperCase
|
||||
- Description: Converts input text to uppercase
|
||||
- Parameters:
|
||||
- `input`: String - The text to convert
|
||||
- Example:
|
||||
```java
|
||||
CallToolResult response = client.callTool(
|
||||
new CallToolRequest("toUpperCase", Map.of("input", "hello world"))
|
||||
);
|
||||
```
|
||||
|
||||
## Available Resources
|
||||
|
||||

|
||||
|
||||
## Available Prompts
|
||||
|
||||

|
||||
- Description: A friendly greeting prompt
|
||||
- Parameters:
|
||||
- `name`: String (required) - The name to greet
|
||||
- Returns: A personalized greeting message
|
||||
|
||||
## Configuration
|
||||
|
||||
The application can be configured through `application.properties`:
|
||||
|
||||
```properties
|
||||
# Server Configuration
|
||||
spring.ai.mcp.server.enabled=true
|
||||
spring.ai.mcp.server.name=my-webflux-server-starter
|
||||
spring.ai.mcp.server.version=0.0.1
|
||||
spring.ai.mcp.server.transport=WEBFLUX
|
||||
|
||||
# Logging Configuration (Required for proper operation)
|
||||
spring.main.banner-mode=off
|
||||
logging.pattern.console=
|
||||
logging.file.name=./target/mcp.webflux-server-starter.log
|
||||
```
|
||||
|
||||
## Implementation Details
|
||||
|
||||
### Server Configuration
|
||||
```java
|
||||
@SpringBootApplication
|
||||
public class McpServerApplication {
|
||||
@Bean
|
||||
public List<ToolCallback> tools(OpenLibrary openLibrary) {
|
||||
List<ToolCallback> tools = new ArrayList<>();
|
||||
|
||||
// Add OpenLibrary tools
|
||||
tools.addAll(List.of(ToolCallbacks.from(openLibrary)));
|
||||
|
||||
// Add toUpperCase tool
|
||||
tools.add(FunctionToolCallback
|
||||
.builder("toUpperCase",
|
||||
(Function<ToUpperCaseInput, String>) s -> s.input().toUpperCase())
|
||||
.description("To upper case")
|
||||
.inputType(ToUpperCaseInput.class)
|
||||
.build());
|
||||
|
||||
return tools;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### OpenLibrary Integration
|
||||
```java
|
||||
@Service
|
||||
public class OpenLibrary {
|
||||
@Tool(description = "Get list of Books by title")
|
||||
public List<Book> getBooks(String title) {
|
||||
// Implementation
|
||||
}
|
||||
|
||||
@Tool(description = "Get book titles by author")
|
||||
public List<String> getBookTitlesByAuthor(String authorName) {
|
||||
// Implementation
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Resource Implementation
|
||||
```java
|
||||
@Bean
|
||||
public List<McpServerFeatures.SyncResourceRegistration> resourceRegistrations() {
|
||||
var systemInfoResource = new McpSchema.Resource(
|
||||
"system://info",
|
||||
"System Information",
|
||||
"Provides basic system information including Java version, OS, etc.",
|
||||
"application/json",
|
||||
null
|
||||
);
|
||||
|
||||
// Resource registration implementation
|
||||
}
|
||||
```
|
||||
|
||||
### Prompt Implementation
|
||||
```java
|
||||
@Bean
|
||||
public List<McpServerFeatures.SyncPromptRegistration> promptRegistrations() {
|
||||
var prompt = new McpSchema.Prompt(
|
||||
"greeting",
|
||||
"A friendly greeting prompt",
|
||||
List.of(new McpSchema.PromptArgument("name", "The name to greet", true))
|
||||
);
|
||||
|
||||
// Prompt registration implementation
|
||||
}
|
||||
```
|
||||
|
||||
## Key Features
|
||||
|
||||
1. **Spring Boot Integration**: Leverages Spring Boot's auto-configuration for easy setup
|
||||
2. **WebFlux Transport**: Uses reactive programming model for efficient request handling
|
||||
3. **OpenLibrary Integration**: Demonstrates external API integration
|
||||
4. **System Resource**: Shows how to expose system information as an MCP resource
|
||||
5. **Function Tools**: Examples of both service-based and function-based tool implementations
|
||||
6. **Prompt Support**: Implements basic prompt functionality with parameter handling
|
||||
|
||||
## Notes
|
||||
|
||||
- The server is configured to use file-based logging to ensure proper operation of the transport layer
|
||||
- Banner mode is disabled to prevent interference with the transport protocol
|
||||
- The OpenLibrary integration demonstrates how to integrate external REST APIs with MCP tools
