About MCP Think Tool Server

MCP Think Tool Server is an MCP server that implements the think tool, giving Claude a dedicated space for structured reasoning. It suits complex tasks that require policy adherence across long chains of tool calls.

Key features

  1. 01Structured thinking space for Claude
  2. 02Thought history with timestamps
  3. 03Statistics on thinking patterns
  4. 04Option to clear thought history

Use cases

  1. 01Breaking down complex problems step by step
  2. 02Maintaining policy adherence in long tool-call chains
  3. 03Resetting thought records when starting a new task

MCP support

This project is an MCP server that exposes the think tool to MCP clients such as Claude.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "think-tool": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "mcp-think-tool"
      ]
    }
  }
}
Run commanddocker run -i --rm mcp-think-tool

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

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.

Docker

You can install this MCP server with only the Dockerfile

First download the Dockerfile, navigate to its directory, and build the Docker image

docker build -t mcp-think-tool .

Then add the following configuration your MCP config file

"think": {
    "command": "docker",
    "args": ["run", "--rm", "-i", "mcp-think-tool"]
}

This was tested and working with Claude Desktop and Cursor

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
