# paywall-mcp

> Use this tool when you need to monetize API or MCP services by requiring payment via Lightning invoices, solving the problem of unauthorized access to priced tools. It takes in tool calls and payment invoices as input, and outputs verified and audited tool calls to the upstream server. Use paywall-mcp in contexts where you want to protect and price standard input/output MCP servers without modifying them.

## Description

Generic Lightning-paywall sidecar that wraps any stdio MCP server and requires a paid Lightning invoice (via NWC) before forwarding priced tool calls. Per-tool prices are set via env; includes payment verification, replay protection, and an audit log — the upstream server stays untouched.
