Think MCP Server

🚀 MCP Server for the "Think" Tool

The official implementation of Anthropic's "think" tool as an MCP server - Significantly enhances Claude's reasoning ability through structured thinking.

🚀 Quick Start

For Claude Desktop

npx -y @smithery/cli@latest install @PhillipRt/think-mcp-server --client claude --config "{}"

For Cursor

npx -y @smithery/cli@latest install @PhillipRt/think-mcp-server --client cursor --config "{}"

✨ Features

This MCP server implements the "think" tool introduced by Anthropic in the Engineering Blog Post. This tool provides Claude with a dedicated space for performing structured reasoning, improving performance when solving complex problems.

Proven Performance Improvements

Anthropic's research demonstrates significant improvements when using the "think" tool:

• 54% improvement in complex customer support tasks
• Significantly better compliance with detailed policies and guidelines
• Enhanced consistency across multiple trials of the same task
• Improved performance on software engineering benchmarks
• Minimal implementation overhead compared to other enhancement techniques

The "think" tool excels where other methods fall short:

• Outperforms chain-of-thought for cases requiring complex toolchains
• More effective than baseline prompting for policy-heavy scenarios
• Particularly powerful when paired with optimized prompting

📦 Installation

Manual Installation

If you prefer to run the server locally:

1. Clone the repository:

   git clone https://github.com/PhillipRt/think-mcp-server.git
   cd think-mcp-server
   

2. Install dependencies:

   npm install
   

3. Build and run:

   npm run build
   npm start
   

4. Manually configure Claude Desktop:

   • Locate or create the configuration file:
     • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
     • Windows: %APPDATA%\Claude\claude_desktop_config.json
   • Add your server configuration:

   {
     "mcpServers": {
       "think-tool": {
         "command": "node",
         "args": ["path/to/think-mcp-server/dist/server.js"]
       }
     }
   }
   

💻 Usage Examples

Basic Usage

The "think" tool implements the same functionality described in Anthropic's engineering blog. This server runs over the WebSocket protocol, and Claude can interact with it by sending messages in JSON format.

Message Structure

All messages must be valid JSON objects and include a command field to specify the type of operation.

Example Request:

{
  "command": "think",
  "prompt": "How can I optimize the performance of my website?"
}

Example Response:

{
  "command": "think",
  "id": 1,
  "result": {
    "step-by-step": ["Analyze the current website architecture", "Identify bottlenecks", "Suggest optimization measures"]
  }
}
