Think

Think-MCP provides a structured set of thinking tools you can run as an MCP server to coordinate, debug, and improve AI reasoning. It exposes modular tools for tracing thoughts, applying mental models, designing patterns, debugging, and more, all accessible through standardized MCP clients or remote endpoints. This lets you organize complex problem solving, debug workflows, and collaborative reasoning with a consistent interface.

How to use

You can use the MCP server locally in stdio mode or connect remotely via an HTTP endpoint. In stdio mode, run the server through a local command and communicate with your MCP client as a standard input/output service. In remote mode, connect your client to the deployed HTTP endpoint to access the same thinking tools without running code locally.

How to install

Prerequisites: you need Node.js installed on your system. Use a recent LTS version (Node.js 18+ is recommended). You also need npm for package management.

# Install the MCP server package globally for local use
npm install -g think-mcp

Additional configuration and remote access

You can run the MCP server locally using the standard CLI interface, or connect to a remote deployment. Below are example configurations you can adapt for your environment.

# Claude Desktop configuration for local usage
{
  "mcpServers": {
    "think-mcp": {
      "command": "npx",
      "args": ["think-mcp"]
    }
  }
}

To deploy Think-MCP to a remote hosting service and access it from Claude Desktop, first deploy to the remote environment and then connect using the provided endpoint.

# Install Vercel CLI
npm i -g vercel

# Deploy to Vercel
vercel

# Claude Desktop remote connection example
{
  "mcpServers": {
    "think-mcp": {
      "command": "npx",
      "args": ["mcp-remote", "https://your-deployment.vercel.app/api/mcp"]
    }
  }
}

If you want to connect ChatGPT to the remote MCP endpoint, use the endpoint URL directly in your advanced connector settings.

Notes and considerations

The local stdio configuration uses the npx command to run the Think-MCP server, which keeps you in a lightweight, quick-start setup. The remote configuration provides access without local installation, enabling collaboration across tools and environments.
