Think Tool MCP Server

Exposes a single think tool for structured prompt engineering and reasoning during MCP-driven interactions.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "piotrpalek-mcp-thinking-tool": {
      "command": "node",
      "args": [
        "/path/to/mcp-think-tool/build/index.js"
      ]
    }
  }
}

You can run the Think Tool MCP server to enable a simple prompt-engineering workflow where the model can separately log its thoughts, break problems into steps, and cache intermediate results during complex reasoning. This server exposes a single tool named think that echoes back input thoughts, helping you reason more clearly and organize the solution process while keeping your data unchanged.

How to use

To use this MCP server, connect your client to the Think Tool server as a local stdio endpoint. You will run the Think Tool locally and point your client at the Node process so the client can call the think tool with a structured thought input. Start by starting the MCP Think Tool server, then configure your client to load the tool and invoke think whenever you want to temporarily store or organize reasoning steps during problem solving.

How to install

Prerequisites you need installed on your machine:

Node.js and npm are required to run the MCP Think Tool server.
A TypeScript runtime is not strictly required for runtime, but ensure npm packages install without errors if you clone the project.
Internet access to fetch dependencies when running npm install.

Step-by-step commands to set up and run the server locally:

# 1) Install dependencies
