x402 Seller — questions

Answers built from our own checks of this server.

Why is there no uptime for x402 Seller?

x402 Seller runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package x402-seller-mcp was installed 334 times last week.

How do I connect x402 Seller?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls x402-seller-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use x402 Seller?

The npm package x402-seller-mcp was installed 334 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is x402 Seller open source?

We cannot say that it is: written in JavaScript and 0 stars on GitHub, but no licence is declared, and without one the code is not open source by default.
