springAI项目 https://start.spring.io/

mcp项目分为server服务端(提供mcp服务),client客户端(去请求mcp服务)

一、创建MCP Server项目

1、pom配置

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

        <version>3.4.4</version>
        <relativePath/> <!-- lookup parent from repository -->

2、yml配置

spring:
  ai:
    mcp:
      server:
        name: webflux-mcp-server
        version: 1.0.0
        type: ASYNC  # Recommended for reactive applications
        sse-message-endpoint: /mcp/messages

 

3、service服务文件

package com.mcp.example;

import org.springframework.ai.tool.annotation.Tool;
import org.springframework.context.i18n.LocaleContextHolder;
import org.springframework.stereotype.Service;

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

/**
 * 定义时间服务
 */
@Service
public class DateTimeService {
    @Tool(description = "Get the current date and time in the user's timezone")
    String getCurrentDateTime() {
        return LocalDateTime.now().atZone(LocaleContextHolder.getTimeZone().toZoneId()).toString();
    }

    @Tool(description = "Set a user alarm for the given time, provided in ISO-8601 format")
    String setAlarm(String time) {
        LocalDateTime alarmTime = LocalDateTime.parse(time, DateTimeFormatter.ISO_DATE_TIME);
        return "Alarm set for " + alarmTime;
    }
}

 

4、provider暴露tools工具

package com.mcp.example;

import org.springframework.ai.tool.ToolCallbackProvider;
import org.springframework.ai.tool.method.MethodToolCallbackProvider;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * 配置暴露这个tool工具
 */
@Configuration
public class McpWebFluxServiceExampleConfig {
    @Bean
    public ToolCallbackProvider dateTimeTools(DateTimeService dateTimeService) {
        return MethodToolCallbackProvider.builder().toolObjects(dateTimeService).build();
    }
}

5、启动服务后控制台

  看到注册了2个工具。

 

二、创建MCP Client项目

1、pom配置

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>3.4.4</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.mcp.example</groupId>
    <artifactId>mcp-client-example</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>mcp-client-example</name>
    <description>mcp-client-example</description>

    <repositories>
        <repository>
            <id>spring-snapshots</id>
            <name>Spring Snapshots</name>
            <url>https://repo.spring.io/snapshot</url>
            <releases>
                <enabled>false</enabled>
            </releases>
        </repository>
        <repository>
            <name>Central Portal Snapshots</name>
            <id>central-portal-snapshots</id>
            <url>https://central.sonatype.com/repository/maven-snapshots/</url>
            <releases>
                <enabled>false</enabled>
            </releases>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
        </repository>
        <repository>
            <id>spring-milestones</id>
            <name>Spring Milestones</name>
            <url>https://repo.spring.io/milestone</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
        <repository>
            <id>spring-snapshots</id>
            <name>Spring Snapshots</name>
            <url>https://repo.spring.io/snapshot</url>
            <releases>
                <enabled>false</enabled>
            </releases>
        </repository>
    </repositories>

    <dependencyManagement>
        <dependencies>
            <dependency>

                <version>1.0.0-M7</version>
                <type>pom</type>
                <scope>import</scope>

        </dependency>
        <!--<dependency>

            </plugin>
        </plugins>
    </build>



</project>

2、yml配置

spring:
  ai:
    dashscope:
      api-key: sk-xxx
    mcp:
      client:
        sse:
          connections:
            server1:
              url: http://localhost:8080
        toolcallback:
          enabled: true
server:
  port: 8081

 

3、通过大模型访问mcp

package com.mcp.example;

import org.springframework.ai.chat.client.ChatClient;
import org.springframework.ai.chat.client.advisor.MessageChatMemoryAdvisor;
import org.springframework.ai.chat.client.advisor.SimpleLoggerAdvisor;
import org.springframework.ai.chat.memory.InMemoryChatMemory;
import org.springframework.ai.tool.ToolCallbackProvider;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/")
public class ChatController {

    private final ChatClient dashScopeChatClient;

    public ChatController(ChatClient.Builder chatClientBuilder, ToolCallbackProvider tools) {
        this.dashScopeChatClient = chatClientBuilder
                .defaultTools(tools)
                .build();
    }

    @GetMapping("/simple/chat")
    public String simpleChat(@RequestParam(value = "query", defaultValue = "10分钟后,设置一个闹铃。")String query) {

        return dashScopeChatClient.prompt(query).call().content();
    }
}

4、测试不同的请求

  先在mcp-server的打断点,看是否会访问到getCurrentDateTIme()方法。

  先访问 http://127.0.0.1:8081/simple/chat?query=你是谁
  再访问 http://127.0.0.1:8081/simple/chat?query=明天星期几

  会发现问题“你是谁”,不会调用getCurrentDateTIme()方法, 而下面涉及到时间有关。则会请求到getCurrentDateTIme()方法。

    下面这个是没有使用mcp的大模型项目,可以看到没有给出准确的时间回答。

  访问 http://127.0.0.1:18081/simple/chat?query=明天星期几

  正常大模型问“明天星期几”不会给出准确的时间。因为它不知道今天是什么时间。
