MCP Think Tool Server

🚀 MCP Thinking Tool Server

A server implementing the Model Context Protocol (MCP) that provides a "thinking" tool specifically for Claude to enhance its complex reasoning capabilities.

🚀 Quick Start

The MCP Thinking Tool Server is designed to empower Claude with enhanced reasoning capabilities. By implementing the Model Context Protocol (MCP), it offers a dedicated "thinking" tool for Claude, enabling more structured reasoning in complex problem - solving tasks.

✨ Features

Overview

This MCP server implements Anthropic's "thinking" tool. This tool provides a dedicated space for Claude to perform structured reasoning in complex problem - solving tasks. According to Anthropic's blog post, using the thinking tool can significantly improve the ability to handle complex tasks, especially those requiring policy compliance and long - term reasoning chains.

Custom Instructions

Add the following custom instructions to Claude to optimize its use of the thinking tool:

You have a "think" tool that provides a dedicated space for structured reasoning. Using this tool can significantly improve your performance in complex tasks:
- Before performing any action or responding to the user, and after receiving tool results, use this tool as a scratchpad:
  - List specific rules applicable to the current request.
  - Check if all necessary information has been collected.
  - Verify that the planned actions comply with all policies.
  - Iteratively check the correctness of tool results.
  - Analyze complex information from web searches or other tools.
  - Plan a multi - step approach before execution.

## How to Use the Thinking Tool Effectively
When using the thinking tool:
1. Break down complex tasks into well - defined steps.
2. Identify key facts, constraints, and requirements.
3. Check for information gaps and plan how to fill them.
4. Evaluate multiple approaches and then select one.
5. Verify that your reasoning is free of logical errors or biases.

Key Use Cases

• Complex Tool Chains: When Claude needs to invoke complex tools and carefully analyze the results.
• Policy Compliance: When navigating environments with detailed guidelines.
• Sequential Decision - Making: When each step depends on the previous one and the cost of errors is high.
• Multi - Step Analysis: Breaking down complex tasks into manageable steps.
