x402-Gated MCP Server
by arifsakib01
Enables purchasing API credit packs through Stripe Checkout, allowing users or agents to pay in fiat and receive pre-loaded API keys with balance tracking.
This server does not currently have a deployable release on Glama. Follow the repository's setup instructions to install and configure it for your MCP client, including any required credentials and local dependencies.
Monetized MCP AI Tools Suite ($0.50 USD) 🚀
A Model Context Protocol (MCP) server providing premium AI developer tools gated by $0.50 USD API Key authorization with automated Stripe fiat checkout.
Clients pay $0.50 USD per tool call — no crypto wallets required, pay with credit/debit card via Stripe, and receive bank payouts.
