Solana X402 Compliance — questions

Answers built from our own checks of this server.

Why is there no uptime for Solana X402 Compliance?

Solana X402 Compliance 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 @msantagiulianab/x402-mcp-server.

How do I connect Solana X402 Compliance?

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

Is Solana X402 Compliance open source?

Yes — it is published under the Apache-2.0 licence, written in Java 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.
