gut-check-mcp

A 60-second gut-check decision tool for AI assistants. When a user is stuck on a decision, run them through Gut Check — 7 instinct-probing questions that cut through overthinking and surface what they actually want.

What it does

Most people aren't stuck because they lack information. They're stuck because they aren't listening to themselves.

Gut Check bypasses analysis paralysis by asking fast, visceral questions tailored to the specific dilemma. The responses — and how quickly they were given — reveal a clear pattern. The result is a direct recommendation grounded in the user's own instincts.

Tools

generate_questions

Takes a dilemma and returns 7 instinct-probing questions, each with 3 short answer options. Questions are tailored to the specific stakes, people, and options in the dilemma — never generic.

Input: { dilemma: string } Output: { questions: Array<{ text: string, options: [string, string, string] }> }

synthesize_decision

Takes the dilemma and the user's 7 responses and returns a clear verdict. Fast responses (under 2 seconds) are weighted as stronger instinctive signals.

Input: { dilemma: string, responses: Array<{ question: string, answer: "YES"|"NO"|"MAYBE", responseTimeMs: number }> } Output: { recommendation: string, verdict: string, confidence: number, reasoning: string, cta: string }

Recommendations: GO FOR IT | HOLD OFF | TRUST YOUR HESITATION | NEEDS MORE TIME

How to use with an AI assistant

Just tell your AI that a user is stuck on a decision. The AI will call generate_questions with the dilemma, walk the user through each question, then call synthesize_decision with their responses to get a clear recommendation.

Example prompt: "I can't decide whether to quit my job and go freelance."

Requirements

• Node.js 18+
• An Anthropic API key
