DeepSeek MCP Server

MCP server for DeepSeek V4 (v4-flash and v4-pro, 1M context) with multi-turn sessions, function calling, thinking mode, and cost tracking.

Compatible with Claude Code, Gemini CLI, Cursor, Windsurf, and any MCP-compatible client. Officially listed on the MCP Registry, Smithery, Glama, LobeHub, and Fronteir AI.

v2.0.0 runs on DeepSeek V4. Two models, deepseek-v4-flash (fast and economical) and deepseek-v4-pro (top capability), both with a 1M-token context window and optional chain-of-thought thinking. Existing deepseek-chat and deepseek-reasoner setups keep working through deprecated aliases, so upgrading is drop-in, but new setups should use the V4 names.

Quick Start

Remote (No Install)

Use the hosted endpoint directly — no npm install, no Node.js required. Bring your own DeepSeek API key:

Claude Code:

claude mcp add --transport http deepseek \
  https://deepseek-mcp.tahirl.com/mcp \
  --header "Authorization: Bearer YOUR_DEEPSEEK_API_KEY"

Cursor / Windsurf / VS Code:

{
  "mcpServers": {
    "deepseek": {
      "url": "https://deepseek-mcp.tahirl.com/mcp",
      "headers": {
        "Authorization": "Bearer ${DEEPSEEK_API_KEY}"
      }
    }
  }
}

Local (stdio)

Claude Code:

claude mcp add -s user deepseek npx @arikusi/deepseek-mcp-server -e DEEPSEEK_API_KEY=your-key-here

Gemini CLI:

gemini mcp add deepseek npx @arikusi/deepseek-mcp-server -e DEEPSEEK_API_KEY=your-key-here

Scope options (Claude Code):

  • -s user: Available in all your projects (recommended)
  • -s local: Only in current project (default)
  • -s project: Project-specific .mcp.json file

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.

Install directly

Runs npx -y @arikusi/deepseek-mcp-server on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add deepseek -- npx -y @arikusi/deepseek-mcp-server
Add to Cursor
