• src/index.ts:52-74 (handler)

  Handler logic for the 'ask_vincent' tool: validates the question input and returns a random 'yes' or 'no' response.

  if (name === "ask_vincent") {
    const question = args?.question;
    if (typeof question !== "string") {
      throw new McpError(
        ErrorCode.InvalidParams,
        "Question must be a string"
      );
    }
  
    // Random yes/no answer like in the Python version
    const answer = Math.random() < 0.5 
      ? "yes, that's a good idea!" 
      : "no! hell no!";
  
    return {
      content: [
        {
          type: "text",
          text: answer,
        },
      ],
    };
  }
