Two Truths and a Twist MCP server

Two Truths and a Twist is an interactive trivia game that leverages the Model Context Protocol (MCP) to create engaging gameplay between AI models and players. The game presents three statements about a topic—two factual truths and one false "twist"—challenging players to identify which statement is the fabrication.

Installation Requirements

• Python 3.13 or higher
• MCP-compatible LLM (like Claude 3)

Installation Options

Via Smithery

To install automatically via Smithery for Claude Desktop:

npx -y @smithery/cli install @ErgodicLabs/twotruthsandatwist --client claude

Via PyPI

Install directly using pip:

pip install ttaat

Or using uv:

uv pip install ttaat

Setting Up the Game

Initialize the Database

Before playing, initialize the game database:

ttaat db upgrade

Start the Server

Launch the MCP server:

ttaat serve

View Game Statistics

Check game statistics with:

ttaat db stats

Connecting an LLM to the Game

Configure MCP Connection

Create a configuration file (e.g., claude_desktop_config.json) with:

{
  "mcpServers": {
    "TwoTruthsAndATwist": {
      "command": "ttaat",
      "args": ["serve"]
    }
  }
}

Place the Configuration File

For Claude Desktop, place this file in the appropriate location:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

Playing the Game

Starting a Game Round

Once connected to an MCP-enabled LLM, start a game with prompts like:

Let's play Two Truths and a Twist! Create a round about space exploration.

Or:

Create a game round about ancient civilizations.

Game Flow

1. The AI creates three statements about your chosen topic (two truths, one twist)
2. You attempt to identify which statement is the twist (false statement)
3. The AI reveals the correct answer and provides explanations for all statements

Game Mechanics

The game functions through MCP tools that:

• Create game rounds with three statements
• Process player guesses
• Reveal the correct answer with explanations
• Track game statistics

The interactive format creates an entertaining trivia experience where the AI both generates content and facilitates gameplay.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "TwoTruthsAndATwist" '{"command":"ttaat","args":["serve"]}'

See the official Claude Code MCP documentation for more details.

For 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 > Tools & Integrations and click "New MCP Server".

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

{
    "mcpServers": {
        "TwoTruthsAndATwist": {
            "command": "ttaat",
            "args": [
                "serve"
            ]
        }
    }
}

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 explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "TwoTruthsAndATwist": {
            "command": "ttaat",
            "args": [
                "serve"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
