Connect Vettoz to Claude, ChatGPT and Cursor

Vettoz researches product ideas and runs as an MCP server. You add it once to the AI you use. From then on “check this idea with Vettoz” comes back as a scored check with the evidence behind it, and your AI writes the report. This guide walks through each app, then your first check.

Claude.ai, desktop and mobile

Claude signs in to your Vettoz account; there is no key to paste.

Create an account at vettoz.si and set your password from the welcome email.
In Claude, open Settings → Connectors and choose Add custom connector.
Name it Vettoz and paste https://vettoz.si/mcp as the URL.
Click Connect, sign in to Vettoz and choose Allow.

The connector follows your account, so it works in the desktop and mobile apps too.

ChatGPT

Open Plugins in the sidebar, click Add in the top right and choose Add custom MCP server.
Name it Vettoz, keep Connection on Server URL, paste https://vettoz.si/mcp and leave Authentication on OAuth.
Tick I understand and want to continue and click Create as a plugin.
Sign in to Vettoz and choose Allow.

Claude Code

Create a key on the Connect page, then run once:

claude mcp add --transport http vettoz https://vettoz.si/mcp --header "Authorization: Bearer vtz_live_…"

Cursor and VS Code

Add this to ~/.cursor/mcp.json (Cursor) or .vscode/mcp.json (VS Code), with the key from the Connect page:

{ "mcpServers": { "vettoz": { "url": "https://vettoz.si/mcp", "headers": { "Authorization": "Bearer vtz_live_…" } } } }

Check your first idea

Start a new chat and describe the idea, the kind and who buys it:

Check this idea with Vettoz: an undated paper planner for adults with ADHD, one page a day with a brain dump area. Physical product, US market.

Your AI picks 3 to 6 keywords a buyer would type and asks you before the check runs, because each check uses one of your ideas or free checks. Vettoz then reads the market in under a minute: Reddit threads and their top comments, X posts, TikTok and YouTube videos, active Meta ads, Google results, and TikTok Shop for a physical product or the App Store for an app.

He scores the idea from 0 to 100 on pain, demand, willingness to pay, room and reach, each with the why, and flags when big players own the market or the evidence is thin.

Get the report

Your AI writes the report from the evidence Vettoz returned: the verdict, quotes with their links, the competitors and their prices, a price for you, keywords and the cheapest next test. Ask for it in your language, and ask your AI to save it: it shows up under Reports in your account, and every call shows up under Usage.

Brand it and make the posts

On a paid idea, ask “Brand this idea with Vettoz.” Your AI proposes names from the check’s evidence, Vettoz checks their domains on the registries, and he renders a brand board, a landing hero and the logo. Then ask for the launch marketing: an Instagram carousel, a static post and three Meta ads, rendered in that brand. Ask for any change and he renders it again, without a new check.
