Think MCP server

Think MCP is an implementation of Anthropic's "think" tool using the Model Context Protocol (MCP). It leverages OpenAI's o3-mini model to provide deep thinking capabilities through a standardized interface, allowing for seamless integration with other tools through stdio transport.

Installation

To set up the Think MCP server, follow these steps:

1. Install the required dependencies:

pip install -r requirements.txt

2. Set up your OpenAI API key by creating or editing a .env file in the root directory:

OPENAI_API_KEY=your_api_key_here

Configuration with Claude Desktop

To configure Claude Desktop to use the MCP server:

1. Open your Claude Desktop configuration file:

macOS

~/Library/Application Support/Claude/claude_desktop_config.json

Windows

C:\Users\YourUsername\AppData\Roaming\Claude\claude_desktop_config.json

2. Add the following configuration:

{
  "mcpServers": {
    "think": {
      "command": "/full/path/to/python",
      "args": [
        "/full/path/to/main.py"
      ]
    }
  }
}

3. Replace the paths with the actual locations on your system.

4. Restart Claude Desktop to apply the changes.

Usage

Once installed and configured, the Think MCP tool becomes available through the Claude Desktop interface. The tool provides deep thinking capabilities that can be invoked through the MCP protocol.

The server runs using stdio transport, enabling seamless integration with Claude Desktop and other compatible tools. It includes comprehensive error handling and logging to ensure reliable operation.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
