X402 Sms — questions

Answers built from our own checks of this server.

Why is there no uptime for X402 Sms?
X402 Sms 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-sms-mcp was installed 38 times last week.
How do I connect X402 Sms?
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-sms-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use X402 Sms?
The npm package x402-sms-mcp was installed 38 times in the last week. Week over week that is -7%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is X402 Sms open source?
Yes — written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
