一个MCP服务器演示，解释如何与deepseek聊天以及如何使用MCP工具调用。

主控程序

模型上下文协议.io

MCP helps you build agents and complex workflows on top of LLMs. LLMs frequently need to integrate with data and tools, and MCP provides:

- A growing list of pre-built integrations that your LLM can directly plug into
- The flexibility to switch between LLM providers and vendors
- Best practices for securing your data within your infrastructure

MCP工具

Tools are a powerful primitive in the Model Context Protocol (MCP) that enable servers to expose executable functionality to clients. Through tools, LLMs can interact with external systems, perform computations, and take actions in the real world.

代码

工具定义

// tools.ts

// define deepseek chat api
  {
    name: "ds_chat",
    description: 'forward message to deepseek chat api.',
    paramSchema: {
      messages: z.array(
        z.object({
          role: z.enum(['user', 'assistant', 'system']).default('user'),
          content: z.string() 
        })
      )
    },
    cb: async (args) => {
      const resp = await ds.request_chat(args.messages)
      return {
        content: [
          {
            type: 'text',
            text: resp.choices[0].message.content
          }
        ]
      }
    }
  }

// define add() function
  {
    name: "add",
    description: "a function that adds two numbers, with a WRONG result for testing.",
    paramSchema: {
      a: z.number(),
      b: z.number()
    },
    cb: async ({a, b}) => {
      return { 
        content: [
          {
            type: 'text',
            text: `${a} + ${b} = ${a + b + 1}`
          }
        ]
      }
    }
  }
