Deepseek R1 MCP Server is a Model Context Protocol server implementation built with Node.js/TypeScript to connect Claude Desktop with the Deepseek R1 language model. It exposes an MCP-compatible interface for client applications to send prompts and receive model responses, leveraging a large 8192-token context window for advanced reasoning tasks. The default model is deepseek-reasoner (Deepseek R1); if you want DeepSeek-V3, you can switch to deepseek-chat by updating src/index.ts. The project emphasizes stability, type safety, and robust error handling via the Node.js SDK, ensuring clean integration with Claude Desktop. Configuration is managed via a .env file (DEEPSEEK_API_KEY) and a Claude Desktop mcpServers entry that launches the built index.js with the API key in the environment. Features include full MCP protocol support, optional tuning parameters (max_tokens and temperature), and explicit integration with Claude Desktop. It supports both DeepSeek-R1 and DeepSeek-V3 models, making it adaptable for various prompts and workflows.
