Agents can use the MPP services catalog before choosing which paid API to call:

SurfaceURLUse it for
Web directoryhttps://mpp.dev/servicesBrowse services, categories, providers, endpoints, and examples.
Public catalog APIhttps://mpp.dev/api/servicesFetch the JSON catalog directly from scripts, CLIs, or custom agents.
