X402ai MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for X402ai MCP?

X402ai MCP 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 x402ai-mcp was installed 608 times last week.

How do I connect X402ai MCP?

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 x402ai-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use X402ai MCP?

The npm package x402ai-mcp was installed 608 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 X402ai MCP open source?

Yes — it is published under the MIT licence, written in TypeScript 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.
