DeepSeek MCP Server

An MCP server implementation that provides code generation and completion capabilities using the DeepSeek API, with support for tool chaining and cost optimization.

Features

Code generation with language-specific support
Code completion with context awareness
Code optimization with multiple targets
Tool chaining for complex operations
Built-in caching for cost optimization
TypeScript implementation with full type safety

Tools

1. generate_code

Generate code using DeepSeek API with language-specific support.

{
  "name": "generate_code",
  "params": {
    "prompt": "Write a function that sorts an array",
    "language": "typescript",
    "temperature": 0.7
  }
}

2. complete_code

Get intelligent code completions based on existing context.

{
  "name": "complete_code",
  "params": {
    "code": "function processData(data) {",
    "prompt": "Add input validation and error handling",
    "temperature": 0.7
  }
}

3. optimize_code

Optimize existing code for performance, memory usage, or readability.

{
  "name": "optimize_code",
  "params": {
    "code": "your code here",
    "target": "performance"
  }
}

4. execute_chain

Execute a chain of tools in sequence, with context passing between steps.

{
  "name": "execute_chain",
  "params": {
    "steps": [
      {
        "toolName": "generate_code",
        "params": {
          "prompt": "Create a REST API endpoint",
          "language": "typescript"
        }
      },
      {
        "toolName": "optimize_code",
        "params": {
          "target": "performance"
        }
      }
    ]
  }
}

Installation

Clone the repository
Install dependencies:

npm install

Build the project:

npm run build

Configure your DeepSeek API key in the MCP settings file:

{
  "mcpServers": {
    "deepseek": {
      "command": "node",
      "args": ["/path/to/deepseek-mcp/build/index.js"],
      "env": {
        "DEEPSEEK_API_KEY": "your-api-key"
      }
    }
  }
}

Usage

The server can be used with any MCP-compatible client. Here's an example using the MCP CLI:

mcp use deepseek generate_code --params '{"prompt": "Write a hello world program", "language": "python"}'

Tool Chaining

Tool chaining allows you to combine multiple operations into a single workflow. Each tool in the chain can access the results of previous tools through the chain context.

Example chain:

Generate initial code
Complete the code with error handling
Optimize the final result

{
  "steps": [
    {
      "toolName": "generate_code",
      "params": {
        "prompt": "Create a user authentication function",
        "language": "typescript"
      }
    },
    {
      "toolName": "complete_code",
      "params": {
        "prompt": "Add input validation and error handling"
      }
    },
    {
      "toolName": "optimize_code",
      "params": {
        "target": "security"
      }
    }
  ]
}

Cost Optimization

The server implements several strategies to optimize API costs:

Request caching with TTL
Chain result caching
Smart prompt construction
Metadata tracking for usage analysis

Development

To start development:

npm run dev

To clean and rebuild:

npm run rebuild
