Put your own value in place of <EVM_PRIVATE_KEY> (User-supplied EVM private key on Base mainnet. Used solely to sign USDC `transferWithAuthorization` payment payloads via x402. Each tool call costs $0.01-$0.06 USDC). The author’s registry entry marks it as required.

Optional settings from the registry entry, left out of the block above: KERDOS_X402_BASE_URL (Optional override of the Kerdos x402 endpoint base URL).

Kerdos X402 MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Kerdos X402 MCP?

Kerdos X402 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 kerdos-x402-mcp was installed 46 times last week.

How do I connect Kerdos X402 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 kerdos-x402-mcp straight from npm; nothing to host, nothing to sign up for.

How many people use Kerdos X402 MCP?

The npm package kerdos-x402-mcp was installed 46 times in the last week. Week over week that is +3%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Kerdos X402 MCP 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.
