## About

# MCP Think Tool Server

A Model Context Protocol (MCP) server implementing the "think" tool for improving Claude's complex reasoning capabilities.

## Overview

This MCP server implements the "think" tool as described in Anthropic's [blog post](https://www.anthropic.com/engineering/claude-think-tool), which provides Claude with a dedicated space for structured thinking during complex problem-solving tasks. The think tool has been shown to significantly improve performance in complex tasks requiring policy adherence and reasoning in long chains of tool calls.

## Features

- **Structured Thinking Space**: Provides Claude with a dedicated place to break down complex problems
- **Thought History**: Maintains a log of all thoughts with timestamps for reference
- **Statistics and Analysis**: Offers metadata about thinking patterns
- **Clean Slate Option**: Allows clearing thought history when starting fresh

## Installation

Install from PyPI:

```bash
pip install mcp-think-tool
```

## Configuration

```json
"think": {
    "command": "/home/xxx/.local/bin/mcp-think-tool",
    "args": [],
    "type": "stdio",
    "pollingInterval": 30000,
    "startupTimeout": 30000,
