What your AI can do with Lumière PayCheck
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “check_endpoint”: Get the trust verdict for one x402 endpoint: score (0-100), grade (A-F), and verdict (proceed, caution, avoid, free, or insufficient_data),.”
“Use “check_payment”: Decide whether a specific x402 payment should go through: returns allow true/false with reasons. Checks the endpoint's trust verdict, that t.”
“Use “report_outcome”: After paying an x402 endpoint, report whether you got what you paid for. Free, optional, and open to every agent: send the receipt from a Lu.”
“Use “top_endpoints”: List the x402 endpoints that are currently safest to pay (verdict proceed or caution, no payout-wallet incidents), best first, with score, g.”
How secure is the Lumière PayCheck MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Lumière PayCheck holds up.
Official endpoint
Operated by Lumière PayCheck (lumierepaycheck.org) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Lumière PayCheck adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.

https://lumierepaycheck.org/mcpQuestions, answered
Is there an official Lumière PayCheck MCP server?
