Deepseek R1 MCP Server

A Model Context Protocol (MCP) server implementation for the Deepseek R1 language model. Deepseek R1 is a powerful language model optimized for reasoning tasks with a context window of 8192 tokens.

Why Node.js? This implementation uses Node.js/TypeScript as it provides the most stable integration with MCP servers. The Node.js SDK offers better type safety, error handling, and compatibility with Claude Desktop.

Quick Start

Installing manually

# Clone and install git clone https://github.com/66julienmartin/MCP-server-Deepseek_R1.git cd deepseek-r1-mcp npm install # Set up environment cp .env.example .env # Then add your API key # Build and run npm run build

Prerequisites

Node.js (v18 or higher)
npm
Claude Desktop
Deepseek API key

Model Selection

By default, this server uses the deepseek-R1 model. If you want to use DeepSeek-V3 instead, modify the model name in src/index.ts:

// For DeepSeek-R1 (default) model: "deepseek-reasoner" // For DeepSeek-V3 model: "deepseek-chat"

Configuration

Create a .env file:

DEEPSEEK_API_KEY=your-api-key-here

Update Claude Desktop configuration:

{ "mcpServers": { "deepseek_r1": { "command": "node", "args": ["/path/to/deepseek-r1-mcp/build/index.js"], "env": { "DEEPSEEK_API_KEY": "your-api-key" } } } }

Development

npm run dev # Watch mode npm run build # Build for production

Features

Advanced text generation with Deepseek R1 (8192 token context window)
Configurable parameters (max_tokens, temperature)
Robust error handling with detailed error messages
Full MCP protocol support
Claude Desktop integration
Support for both DeepSeek-R1 and DeepSeek-V3 models

API Usage

{ "name": "deepseek_r1", "arguments": { "prompt": "Your prompt here", "max_tokens": 8192, // Maximum tokens to generate "temperature": 0.2 // Controls randomness } }

The Temperature Parameter

The default value of temperature is 0.2.

Deepseek recommends setting the temperature according to your specific use case:

USE CASE	TEMPERATURE	EXAMPLE
Coding / Math	0.0	Code generation, mathematical calculations
Data Cleaning / Data Analysis	1.0	Data processing tasks
General Conversation	1.3	Chat and dialogue
Translation	1.3	Language translation
Creative Writing / Poetry	1.5	Story writing, poetry generation
