MCP X402 Accept runs on your own machine — the client starts it, so there is no endpoint to ping. 46 installs a week from npm. Last commit 30 Jul 2026.
Self-hosted MCP proxy that puts an x402 paywall in front of an existing MCP server
Today is the operative word: we check MCP X402 Accept every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
