Agents assemble pages from whatever is in context, and context routinely contains live credentials: the bearer token that fetched the data, the key in a pasted config. What a pre-flight secret scan catches (API key prefixes, JWTs, Luhn-checked card numbers, SSNs, emails), why the MCP publish path blocks by default, what a regex net honestly cannot promise, and what to do when a key already shipped.

A working x402 example on Base mainnet: an agent hits a 402, signs an EIP-3009 USDC authorization, pays $1 with no human and no card, gets a persistent API key, and publishes a live page. The whole loop, the real transaction, and the bug that cost two attempts.
