配置

spring.application.name=mcpServer

spring.ai.mcp.server.enabled=true
spring.ai.mcp.server.name=mcp-server
spring.ai.mcp.server.version=1.0.0
spring.ai.mcp.server.sse-endpoint=/sse
spring.ai.mcp.server.sse-message-endpoint=/mcp

spring.ai.mcp.server.capabilities.resource=false
spring.ai.mcp.server.capabilities.prompt=false

logging.level.org.springframework.ai.mcp=DEBUG



server.port=8081

cline配置

启动项目后，在cline里配置好deepseek的apiKey

然后在MCP Servers里配置本地的mcp Server服务器

按本地配置的填入后是长这样

点击add Server，可以看见加入成功，且成功连接

这时候再去问ai，某个城市的天气怎么样，ai就会识别去调用mcp的服务器去查询。
