This one needs environment variables set before it will start: JMT_X402_PRIVATE_KEY (Base-mainnet wallet private key (funded with USDC). Used only to sign x402 payment authorizations. Never logged.). The author declared them in the registry entry; get the values from the project itself.

X402 MCP Server — questions

Answers built from our own checks of this server.

Why is there no uptime for X402 MCP Server?

X402 MCP Server 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 @jmthomasofficial/x402-mcp-server was installed 70 times last week.

How do I connect X402 MCP Server?

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

How many people use X402 MCP Server?

The npm package @jmthomasofficial/x402-mcp-server was installed 70 times in the last week. Week over week that is +74%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is X402 MCP Server open source?

We cannot say either way: written in JavaScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
