An MCP server that enhances Claude's reasoning capabilities by integrating DeepSeek R1's advanced reasoning engine. This server provides Claude with access to DeepSeek's state-of-the-art reasoning model, developed through large-scale reinforcement learning.

• Advanced Reasoning Integration

  • Leverages DeepSeek R1's reasoning engine
  • Seamlessly integrates with Claude's thought process
  • Handles complex multi-step reasoning tasks

• Enterprise-Grade Security

  • Environment variable support (.env file)
  • Secure API key handling
  • No key exposure in responses

• MCP Protocol Support

  • Full MCP server implementation
  • Streaming response handling
  • Proper error management

• Modern Python Architecture

  • Async/await for efficient processing
  • Proper exception handling
  • Clean code organization

1. Prerequisites

   • Python 3.12+
   • uv package manager
   • DeepSeek API key (get one from platform.deepseek.com)

2. Quick Start

# Clone repository
git clone https://github.com/martinbowling/thoughtful-claude.git
cd thoughtful-claude

# Install MCP and dependencies
pip install "mcp[cli]" httpx python-dotenv

# Create .env file with your API key
echo "DEEPSEEK_API_KEY=your_key_here" > .env

# Install the MCP server with environment variables
mcp install server.py -f .env

The mcp install command will:

• Register the server with Claude Desktop
• Set up the environment variables from .env
• Configure the server to run with the correct Python interpreter

You can verify the installation by checking for the 🔨 Tools icon in Claude Desktop's interface.

1. Start the Server The server will automatically start when you use Claude Desktop with the proper configuration.

2. Basic Workflow

   • Claude receives a query requiring reasoning
   • Query is sent to DeepSeek R1 for advanced reasoning
   • Reasoning is returned to Claude wrapped in <ant_thinking> tags
   • Claude incorporates the reasoning into its response

3. Example Queries

   • Mathematical comparisons: "Is 9.9 greater than 9.11?"
   • Logic puzzles: "If all A are B, and some B are C, what can we conclude?"
   • Complex analysis: "Compare and contrast quantum computing with classical computing"

1. Query Processing

   • Accepts context and question in structured format
   • Combines inputs for comprehensive reasoning

2. DeepSeek R1 Integration

   • Model: deepseek-reasoner
   • Stream: Enabled for real-time processing
   • Max Tokens: 1 (optimized for reasoning extraction)
   • Output: Structured reasoning content

• API Errors

  • Graceful error wrapping in <ant_thinking> tags
  • Clear error messages for debugging
  • Proper exception propagation

• Connection Issues

  • Timeout handling (30s default)
  • Automatic stream cleanup
  • Resource management

Common Issues

# Server not found in Claude Desktop
ERROR: MCP server not detected

# Solution
Check claude_desktop_config.json path and format

Performance Tips

• Keep queries focused and specific
• Provide relevant context when available
• Use structured input format for complex queries
