x402station MCP server

Lets your AI check whether an x402 payment endpoint is safe before it pays.

This is a helper for AI agents that pay for things online using a system called x402. Before your AI sends money to an endpoint, this server checks whether that endpoint looks safe or shady. It is handy if you are building or running an AI that pays for data or services on its own.

What is an MCP server? The 30-second version

On its own, your AI can only chat. An MCP server is a small helper program that gives your AI a new skill or a connection to an app or service. This one connects your AI to x402station.io, a service that watches x402 payment endpoints and reports on them. Once connected, your AI can ask x402station whether a specific endpoint is safe to pay before it signs a payment.

What this MCP server does

You or your AI ask about a specific web address that wants to be paid. The AI uses this helper, and the helper talks to x402station.io. x402station looks at its probe history and settlement data for that address, then sends back a verdict. You get a simple answer: is it ok to pay, and if not, what looks wrong.

Flow diagram: you ask your AI “Is it safe to pay this link before I pay it?”, the x402station MCP server connects it to x402station.io, and you get back safe to pay or not, with reasons.

Try asking your AI

“Is it safe to pay https://some-endpoint.com/data?”
“Run a preflight check on this x402 URL before I pay it”
“Give me the full 7-day forensics report for this endpoint”
“Pull the current list of flagged decoy endpoints”

What it gives back to you

You get a short answer in the chat: ok true or false, a list of warnings, and some basic facts like the price, uptime, and average speed. The forensics tool returns a deeper report with hourly uptime and latency numbers. The catalog tool returns a list of flagged endpoints with counts by reason.
