MCP Think

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

Overview

This MCP server implements the "think" tool as described in Anthropic's blog post, 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 LLMs with a dedicated place to break down complex problems
• Thought History: Maintains a log of all thoughts with timestamps for reference
• Multiple Transport Support: Works with both stdio and SSE transports

Installation

Install from PyPI:

pip install mcp-think

Or install from source:

git clone https://github.com/ddkang1/mcp-think.git
cd mcp-think
pip install -e .

Usage

You can run the MCP server directly:

mcp-think

By default, it uses stdio transport. To use SSE transport:

mcp-think --sse

You can also specify host and port for SSE transport:

mcp-think --sse --host 127.0.0.1 --port 3001

Configuration

To use this tool with Claude in Windsurf, add the following configuration to your MCP config file:

"think": {
    "command": "/home/xxx/.local/bin/mcp-think",
    "args": [],
    "type": "stdio",
    "pollingInterval": 30000,
    "startupTimeout": 30000,
    "restartOnFailure": true
}

The command field should point to the directory where you installed the python package using pip.

Available Tools

The MCP server provides the following tool:

• think: Record a thought with a timestamp
