How to Set Up and Use DeepSeek
The DeepSeek MCP Server integrates DeepSeek AI's chat and reasoning models directly into any MCP-compatible AI client, providing multi-turn conversation management, extended thinking mode, JSON-mode output, and function calling support — all with per-request cost tracking. It ships as an npm package and can be run locally via npx, as a globally installed CLI, or connected to a hosted cloud endpoint, making it the fastest path to using DeepSeek-chat or DeepSeek-reasoner alongside Claude or other AI tools. The server also exposes resources for querying available models with their pricing and inspecting live usage statistics.
Prerequisites
- Node.js 18 or higher installed
- A DeepSeek API key (obtained from https://platform.deepseek.com)
- npm or npx available in your PATH
- An MCP-compatible client such as Claude Desktop, Claude Code, Cursor, or Windsurf
Obtain a DeepSeek API key
Sign up at https://platform.deepseek.com and generate an API key from the API Keys section of your account dashboard.
Add the server to Claude Code via CLI (quickest method)
Use the Claude Code CLI to register the server for the current user. Replace 'your-key-here' with your actual DeepSeek API key.
claude mcp add -s user deepseek npx @arikusi/deepseek-mcp-server -e DEEPSEEK_API_KEY=your-key-hereOr add to Claude Desktop via config file
Add the server block to claude_desktop_config.json if you prefer Claude Desktop or want to set additional options.

Ask Claude to list available DeepSeek models or check the server configuration to confirm the connection is working.

Add this to claude_desktop_config.json. DEEPSEEK_API_KEY is required; the other env vars are optional overrides.

Invoke DeepSeek models through Claude using the deepseek_chat and deepseek_sessions tools.
- "Use DeepSeek to explain the difference between RAG and fine-tuning in plain English"
- "Ask DeepSeek reasoner to solve this math problem step by step: what is the sum of the first 100 prime numbers?"
- "Start a DeepSeek session and ask it to review this Python function for bugs, then follow up with a refactored version"
- "What DeepSeek models are available and what are their current prices per million tokens?"
- "Show me the current DeepSeek usage statistics for this session"Troubleshooting DeepSeek
Authentication error: Invalid API key
Verify DEEPSEEK_API_KEY is set correctly in the env block of your config. Keys are available at https://platform.deepseek.com under API Keys. Ensure there are no extra spaces or quotes around the value.
npx @arikusi/deepseek-mcp-server takes a long time to start
The first run downloads the package from npm. Subsequent runs use the npx cache and are faster. Alternatively, install globally with 'npm install -g @arikusi/deepseek-mcp-server' to avoid repeated downloads.
Multi-turn session context is lost between conversations
Session history is retained for SESSION_TTL_MINUTES (default: 30 minutes). Pass the same session_id in each deepseek_chat call to maintain context. If sessions expire too quickly, set SESSION_TTL_MINUTES to a higher value in the env block.
