Overview

x402node's open-source MCP server (x402node-mcp) lets an agent discover x402-paid APIs from the Coinbase CDP Bazaar and automatically settle the USDC micropayments on Base when calling them. An agent builder plugs it in to give an agent pay-per-call access to x402 endpoints without hand-rolling payment headers. It signs payments from a wallet key — the project itself recommends using a fresh, low-balance wallet.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

Install — not run by us — no falsifiable install+entry probe from deploy_spec

Runtime: Node.js

git clone https://github.com/x402node/x402-mcp
cd x402-mcp
npm install
cp .env.example .env
node mcp-server.js

You supply: X402_PRIVATE_KEY (Base EOA private key, hex 0x-prefixed, with USDC on Base mainnet — risk: controls funds), MAX_PRICE_USD (optional, default $0.10 per call spending cap)

Add to CursorAdd to VS Code
claude mcp add satohub-x402node-mcp -- npx -y x402node-mcp

A local server: your client runs this command on your machine. Installing runs third-party software under your own credentials. Sato Hub publishes the documented invocation and, where the harness reproduced it, the date it did — neither is a safety review.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 46 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.

A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
