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

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.

• 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

Install from PyPI:

pip install mcp-think-tool

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.

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
