MCP.Pizza Chef: DannyMac180

Four small tools, and not one of them touches the internet or your files. The first records a written thought, the second reads back everything recorded so far, the third clears the list, and the fourth reports simple counts. Think memo pad rather than connector: nothing is fetched and nothing is changed. Notes vanish when you close the app, because they are only held in memory. No account and no payment involved. The code has not changed since April 2025.

README

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, 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:

pip install mcp-think-tool

Configuration

Windsurf

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-tool",
    "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.

mcp-think-tool FAQ

Does it need an account, key or payment?
None of the three. It runs entirely on your own machine and never makes a network request, so there is nothing to sign up for.
Can it look things up online or read my documents?
No, and that surprises people. It only stores text that your assistant writes into it. All the usefulness comes from the assistant slowing down, not from any new information.
Are the notes kept between sessions?
No. They live in memory only, so closing the app or restarting the connector wipes them with no way to get them back.
Can I use this to get better answers on fiddly multi-step problems?
Yes, that is the whole idea. It comes from Anthropic's own write-up on giving a model a place to pause and check its reasoning partway through a long task.
Which apps does it work in?
Claude Desktop, Cursor and Windsurf are the ones the author tested. There is an open report that at least one other editor cannot see its tools at all, so try it before relying on it.
How hard is setup?
You either install a Python package from the command line and then point your app at the exact file path it landed in, or build a container yourself. Both are a step past pasting a snippet.
Is it still maintained?
The last code change was April 2025 and the published package has never moved past its first release, so treat it as finished rather than actively developed.
