x402 Research — questions

Answers built from our own checks of this server.

Why is there no uptime for x402 Research?

x402 Research 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 @agentfirm402/x402-research-mcp.

How do I connect x402 Research?

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 @agentfirm402/x402-research-mcp straight from npm; nothing to host, nothing to sign up for.

Is x402 Research open source?

Yes — it is published under the MIT licence, 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.
