Connecting to the Server

To connect an MCP-compatible LLM to the game server, you’ll need to configure the MCP connection. Create a configuration file (e.g., claude_desktop_config.json) with the following content:

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

For Claude Desktop, place this file in:

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

Game Mechanics

Two Truths and a Twist is a trivia game where:

1. The AI creates a round with three statements about a topic - two truths and one “twist” (a playful, false statement)
2. Players try to identify which statement is the twist
3. The AI reveals the answer with entertaining explanations

The game leverages the MCP protocol to provide a fun, interactive trivia experience where AI models both generate the content and facilitate gameplay.

Example Prompts

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

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

Create a game round about ancient civilizations.
