You can use this MCP server to generate, complete, and optimize code with DeepSeek, chaining tools for complex workflows while keeping costs in check. It provides a TypeScript implementation with strong typing and easy integration into MCP-compatible clients.

How to use

Start by ensuring you have a compatible MCP client and the necessary access to the DeepSeek API. You can invoke generation, completion, and optimization steps individually or chain them together to form a workflow that sustains context across steps.

Typical usage patterns include generating initial code, progressively refining it with completions and validations, and then optimizing the final result for performance or readability. You can run a sequence where you first create code, then add error handling and input validation, and finally optimize for a target such as performance or security.

To try a concrete example from a client, request code generation for a specific task and language, then progressively enhance the results. For instance, generate a REST API endpoint in TypeScript, then apply a completion pass for error handling, followed by optimization aimed at performance.

How to install

Prerequisites you need before installing this MCP server: Node.js version 18 or newer, a DeepSeek API key, and an MCP-compatible client.

Install dependencies and build the project, then configure your MCP settings to authenticate with the DeepSeek API.

npm install
```

```
npm run build

Configuration and startup

Configure your MCP settings to point to the DeepSeek MCP server and provide the API key required for authentication.

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

Usage with an MCP client

Use your MCP client to invoke generation, completion, and optimization tasks by name and pass parameters as needed.

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

Available tools

generate_code

Generate code using DeepSeek API with language-specific support, given a prompt and language.

complete_code

Provide intelligent code completions based on existing context and a guiding prompt.

optimize_code

Optimize code for a chosen target such as performance or readability.

execute_chain

Run a sequence of tools in order, passing context between steps to form a cohesive workflow.
