Billing MCP By SubscriptionFlow

SubscriptionFlow is a usage-based billing plugin for MCP servers that lets you monetize apps and assistants down to the single action. Key capabilities: • Bill per question answered, task completed, or custom action • Prepaid credit wallets and post-billing options • Real-time balance checks that prevent overspending • Dynamic usage rates and metered event tracking • Hybrid and tiered pricing models • Payment gateway connections with Stripe, PayPal, and Authorize.net SubscriptionFlow meters every event as it happens, so usage turns into invoices without spreadsheets or manual reconciliation. Set rates that match the value of each action, and protect your margins by stopping customers from spending beyond their balance before costs pile up. Because prepaid and postpaid billing both run on the same platform, you can choose the model that fits each customer segment. Dunning tools recover failed payments, while reports on revenue and usage help you spot which features drive the most value. Built for SaaS founders, developers, and product teams shipping AI-powered apps, chatbots, and agent services who need to charge fairly for consumption. It is especially useful for businesses that want per-action pricing without building custom billing infrastructure.
