Lumière PayCheck MCP
Inspect x402 endpoint reports and apply spending rules to supported agent payment workflows.
Overview
Lumière PayCheck documents tools for checking an x402 endpoint and seeing why the service assigned a particular grade. Its API documentation distinguishes its own paid checks from reports submitted by buyers. That distinction matters when deciding what evidence a score actually contains. The project also describes scoped agent keys, spending caps and an authorization response with reasons. Review those settings before connecting a paying agent. A score or authorization decision does not guarantee that an external service will behave the same way on the next request.
