Contact Verify (verify-x402) — questions

Answers built from our own checks of this server.

Why is there no uptime for Contact Verify (verify-x402)?
Contact Verify (verify-x402) 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 contact-verify-mcp was installed 79 times last week.
How do I connect Contact Verify (verify-x402)?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls contact-verify-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Contact Verify (verify-x402)?
The npm package contact-verify-mcp was installed 79 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.
