About paywall-mcp
paywall-mcp is an MCP server published by the GitHub account llmops-pro. Lightning-paywall sidecar: wraps any stdio MCP server, requires paid invoices before tool calls.
It runs on your own machine: your AI client starts it from the npm package paywall-mcp at version 0.1.2.
It asks for one secret: NWC_CONNECTION_STRING. Give it a key with the least access that still works.
It also needs PAYWALL_UPSTREAM_COMMAND set before it starts.
Version 0.1.2 was published on 12 June 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
