Rekey — auth, billing, and MCP for agent products
The OAuth 2.1 authorization server your MCP server needs (discovery, dynamic client registration, PKCE), plus credits, usage quotas, and licences your agent bills against. Two MCP servers. Self-hostable and MIT licensed.
StackScope records what new websites are built with, the week they launch. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We crawled this one for its tech stack and scored it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 19 August 2026; the live site may have changed since.
Every technology below links to its own page: which other new sites launched with it. Vendors and agencies watch those pages with Stackdar and hear about new adopters the week they ship, from £15 a month.
Rekey — auth, billing, and MCP for agent products looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
The site is served through Cloudflare, with a domain registered 1 week before launch. We've detected 14 technologies on this site, covering analytics, business email, CDN, and chat widgets. The stack includes Next.js, React, and Tailwind CSS.
It's running the same core stack as 5,872 other launches.

Vibe Score Breakdown How?
| Signal | Points |
|---|---|
| AI copy signals | +5 |
| AI onboarding signals | +5 |
This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
