PayPerScreen MCP Server

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Connect this server

This one needs environment variables set before it will start: PAYPERSCREEN_PRIVATE_KEY (Private key of a wallet holding a few dollars of USDC; pays 1 to 2 cents per check. Free tools work without it.), PAYPERSCREEN_MAX_SPEND (Maximum USD the server may spend per session (default 1.00).), PAYPERSCREEN_NETWORK (Where the wallet holds USDC: base (default), polygon or arbitrum.). The author declared them in the registry entry; get the values from the project itself.
