Vercel's Model Context Protocol server now handles real purchases: Pro plan upgrades, prepaid credits for v0 and AI Gateway, the Enterprise-tier SIEM log streaming add-on, and domain registration.
The flow is gated. Vercel MCP quotes the price, flags whether the charge is one-time or recurring, and only executes after explicit user confirmation. When pricing is dynamic or unavailable, it surfaces the relevant billing page instead of guessing. Billing access at the team role level and a valid payment method are both required.
The changelog entry is worth reading for the exact capability boundaries: what triggers a confirmation prompt, how prepaid credit purchases differ from subscription upgrades, and where the SIEM add-on requirement for Enterprise sits in the flow.
