Nothing serious here today

Today is the operative word: we check X402station 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.

This one needs environment variables set before it will start: AGENT_PRIVATE_KEY (0x-prefixed 64-hex-char private key. Account must hold Base mainnet USDC. Required for any paid tool call.), X402STATION_BASE_URL (Optional override. Only https://x402station.io or http(s)://localhost are accepted to prevent payload hijacking; any other value makes the adapter refuse to start.). The author declared them in the registry entry; get the values from the project itself.

X402station — questions

Answers built from our own checks of this server.

Why is there no uptime for X402station?
X402station 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 x402station-mcp was installed 47 times last week.
How do I connect X402station?
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 x402station-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use X402station?
The npm package x402station-mcp was installed 47 times in the last week. Week over week that is -28%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is X402station open source?
Yes — it is published under the MIT licence, written in JavaScript, 3 stars on GitHub and 2 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
