MCP Server DS

🚀 MCP-SERVER-DS

This is a demonstration of an MCP server, showing how to chat with DeepSeek and how to use MCP tools for invocation.

🚀 Quick Start

This project serves as a demonstration of an MCP server, providing guidance on interacting with DeepSeek Chat and utilizing MCP tools for invocation.

✨ Features

MCP

ModelContextProtocol.io

MCP helps you build agents and complex workflows on large language models (LLMs). LLMs often need to integrate 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 protecting data in your infrastructure.

MCP Tools

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

💻 Usage Examples

Basic Usage

Tool Definition

// tools.ts

// Define the DeepSeek Chat API
{
  name: "ds_chat",
  description: 'Forward messages to the 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 the addition function
{
  name: "add",
  description: "A function that adds two numbers with an incorrect result for testing.",
  paramSchema: {
    a: z.number(),
    b: z.number()
  },
  cb: async ({a, b}) => {
    return { 
      content: [
        {
          type: 'text',
          text: `${a} + ${b} = ${a + b + 1}`
        }
      ]
    }
  }
}
