Gemini How It Works
Your AI agent receives a product launch brief and draft copy. Phase 1: the agent runs `validate_product_discovery`. Problem Validation: the founder claims 'developers waste 4 hours per week on code reviews.' Evidence check: is this from user interviews (how many?), usage data (what metric?), or industry reports (which ones)? If the evidence is '3 developers I talked to at a conference,' the hypothesis is unvalidated , anecdotal evidence from 3 self-selected individuals cannot support a launch.
Willingness to Pay: has anyone actually paid for a solution? Pre-orders, pilot contracts, or letter of intent count. 'People said they would pay' does not count , stated preference diverges from revealed preference by 3-5x.
Alternative Analysis: what do developers currently do instead? If they use a combination of GitHub PR templates + Slack reminders + manual checklists, the switching cost is distributed across multiple tools.
The new product must beat the entire incumbent stack, not just one tool. Verdict: DISCOVERY_WEAK , needs 15+ validated interviews and at least one paid pilot.
Phase 2: the agent runs `validate_persuasion_copy` against whatever evidence exists. Proof Hierarchy: the copy claims 'save 4 hours per week' , but the discovery audit found this number is unsupported.
The prover flags this as an unsubstantiated claim that will erode trust if a sophisticated buyer investigates. Loss Aversion: the copy leads with '4 hours wasted per week = 200 hours per year = $15,000 per developer.' The loss calculation is emotionally powerful, but if the underlying metric is unvalidated, the entire persuasion structure collapses on first contact with a skeptic.
Narrative Arc: Problem (wasted time) Solution (AI-assisted reviews) Transformation (reclaimed hours) , the arc is structurally sound but built on an unverified foundation.
The recommendation: rewrite the copy using only validated evidence, or go back and validate the hypothesis before launching.
MCP Server Orchestration: 2 MCP Servers, one intelligent agent
Connect Product Discovery Prover and Persuasion Copywriting Prover MCP servers so your AI agent validates product-market fit evidence before auditing launch copy. Phase 1: the agent runs the Product Discovery Prover to verify that the product hypothesis is grounded in real behavioral data , checking willingness to pay, problem severity, existing alternatives, and switching costs. Phase 2: the agent runs the Persuasion Copywriting Prover to audit the launch copy against the validated evidence, ensuring claims match reality, proof hierarchy uses actual product data, and psychological triggers align with verified pain points. The result is launch copy that converts because it is built on truth , not on what the founder hopes the market wants.

Superpowers you didn't know your AI had
The Vinkius catalog gives your agent access to 4,700+ MCP servers and the intelligence to combine them. Imagine never logging into another dashboard. Your AI handles the work across every tool, in one conversation. That's what this infrastructure was built for.
Cross-Platform Intelligence
Your agent doesn't just connect to tools. It understands the relationships between them. Data flows where it needs to go, automatically, with full context preserved across every platform.
Contextual Reasoning
Every decision your agent makes considers the full picture. It reads CRM data, checks calendars, reviews conversation history, and acts on everything at once. Not step by step. All at once.
Productivity at Scale
What used to take 45 minutes across five different dashboards now takes one sentence. Your agent runs the entire workflow end to end while you focus on decisions that actually matter.
Zero-Config Reliability
No API keys to paste. No webhooks to configure. No YAML to debug. Connect your MCP servers once, and your agent handles the rest. Every time, without intervention.
Made for
exactly this
Your AI agent taps into the entire Vinkius MCP catalog to handle these for you. You describe what you need. It does the rest.
Startup founders preparing Product Hunt or launch day copy who need to ensure their messaging claims are supported by actual user validation data
Product marketers writing feature announcement copy who need systematic verification that benefit claims match measured user outcomes from beta testing
Indie hackers launching solo products who need a framework to validate their assumptions before investing in conversion copy that may be built on wishful thinking
Growth teams running paid acquisition campaigns who need landing page copy where every claim is traceable to validated user research to avoid high-churn conversion
Frequently Asked Questions About This MCP Server Orchestration
Which MCP servers do I need?
Two: Product Discovery Prover and Persuasion Copywriting Prover. Connect both to your AI client.
Does this work with Claude Desktop, Cursor or Windsurf?
Yes. Any AI client that supports the Model Context Protocol works.
What if we have not validated the product yet?
That is exactly the point. The workflow will tell you what evidence you are missing before you spend money on launch copy. Better to discover weak validation before launch than after.
Can this work for feature launches, not just product launches?
Yes. Feature launches also benefit from validation , does the feature solve a measured problem? Is the claimed benefit supported by beta data? Apply the same rigor to features as to products.
What counts as validated evidence?
Behavioral evidence: paid pilots, usage data, time-tracking metrics, conversion rates. NOT: survey responses, stated intentions, founder intuition, or 'people seem interested.' The gap between what people say and what they do is the graveyard of startups.

MCP servers used in this workflow
Product Discovery Prover
Product Discovery Prover is an MCP server that forces product teams to validate market needs before writing code. It requires hard data on problem scale, defines customers by specific behaviors, mandates hands-on competitor testing, and verifies actual financial commitment to prove a concept.
Persuasion Copywriting Prover
Persuasion Copywriting Prover validates marketing copy against core psychological principles. It doesn't write text; it runs your existing copy through seven expert pivots—checking for emotional triggers, required proof types, correct framework usage (AIDA/PAS), and the absence of robotic AI language. Use this tool to ensure every word converts.
