MCP Pay Gate runs on your own machine — the client starts it, so there is no endpoint to ping. 34 installs a week from npm. Last commit 12 May 2026.
Dual-rail Lightning paywall for MCP servers: accepts L402 and x402 bip122/exact, one LNBits backend.
Today is the operative word: we check MCP Pay Gate every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
