DeepSeek-Claude MCP Server

a MCP server which integrates reasoning capabilities of DeepSeek R1 model into claude desktop app.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "harshj23-deepseek-claude-mcp-server": {
      "command": "uv",
      "args": [
        "--directory",
        "C:\\ABSOLUTE\\PATH\\TO\\PARENT\\FOLDER\\deepseek-claude",
        "run",
        "server.py"
      ]
    }
  }
}

DeepSeek-Claude MCP Server enhances Claude's reasoning by wiring in DeepSeek R1’s advanced reasoning engine. This MCP enables Claude to tackle complex, multi-step tasks with precise, thoughtful responses by leveraging the DeepSeek reasoning capability from the DeepSeek platform.

How to use

Use this MCP with your Claude Desktop client to enable enhanced reasoning workflows. When you submit queries that require multi-step analysis, Claude will delegate the reasoning to the DeepSeek R1-backed engine and then integrate the resulting structured reasoning into its final answer.

How to install

Prerequisites include Python 3.12 or higher, the uv package manager, and a DeepSeek API key.

Follow these steps to install and configure the MCP server locally on your machine.

npx -y @smithery/cli install @HarshJ23/deepseek-claude-MCP-server --client claude

Additional sections

Configuration and startup are done through a local MCP configuration file. The server is started via the uv runtime, and you must point the MCP client to the correct server command.

Configure your MCP server by editing the claude_desktop_config.json to include the DeepSeek-Claude entry, which points uv to run the server file from your local clone.

{
    "mcpServers": {
        "deepseek-claude": {
            "command": "uv",
            "args": [
                "--directory",
                "C:\\ABSOLUTE\\PATH\\TO\\PARENT\\FOLDER\\deepseek-claude",
                "run",
                "server.py"
            ]
        }
    }
}

Start the server using uv by running the following command in your terminal from the repository clone.

uv run server.py

Notes and testing

After starting the server, restart Claude Desktop to ensure the MCP server is detected. Look for the tools icon in the Claude interface to verify the integration. If the server is not visible, consult the troubleshooting steps for common configuration issues.
