DeepSeek MCP Server

An MCP server for DeepSeek's current V4.1 Flash API: text and visual chat, the Responses API, FIM completion, Files API lifecycle operations, model discovery, balance checks, and bounded in-memory conversations. Its 11 documented tools cover file, completion. It runs locally over stdio via the published package.

People who work with file and completion and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install DeepSeek MCP Server

before you install - you'll need

Set DEEPSEEK_API_KEY, MCP_TRANSPORT, MCP_HTTP_HOST, MCP_HTTP_PORT, MCP_HTTP_ALLOWED_ORIGINS, DEEPSEEK_BASE_URL, DEEPSEEK_REQUEST_TIMEOUT_MS, DEEPSEEK_DEFAULT_MODEL, MCP_HTTP_PATH, CONVERSATION_MAX_MESSAGES, DEEPSEEK_MCP_AUTH_TOKEN before connecting.

Claude Code

claude mcp add dmontgomery40-deepseek-mcp-server -- npx -y deepseek-mcp-server

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "dmontgomery40-deepseek-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "deepseek-mcp-server"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
