Upgrade
From Billing in app.heymcp.dev. That takes you to Stripe Checkout; your plan updates as soon as the payment completes. Your Pro entitlements apply to new sessions. A tunnel already running keeps the retention window it was stamped with when it opened — restart it to pick up the 7-day window.Manage your subscription
The Billing page links to the Stripe billing portal, where you can update your payment method, download invoices, and cancel.Custom domains
Pro includes one custom domain. The backend can grant more — a Pro subscription’s Stripe quantity above 1 adds one extra domain per unit — but there is no self-serve way to buy them yet. Get in touch if you need a second.That quantity is domains, not seats. HeyMCP has no team model, so raising it
never adds users. See No teams.
Cancelling
Cancel from the Stripe portal. You keep Pro until the end of the period you’ve paid for — the plan doesn’t drop the moment you click. When it does drop:- Existing history is not deleted. Retention was stamped at session registration, so sessions opened while you were on Pro keep their 7-day window.
- New sessions get Hobby limits — 24-hour history, 3 concurrent tunnels, no custom slug or domain.
- Custom domains stop being usable for new tunnels. The DNS records are yours; nothing is deleted at your registrar.
