  These three scopes were read from Google's own MCP setup page and from the Google Wallet API
  Discovery document, which declares its scope set machine-readably.

  The Wallet REST API is single-scope: one coarse scope authorises read AND write across every
  pass type and the issuer/permissions surface. An agent cannot be granted read-only Wallet REST
  access. The newer MCP surface is the only Google Pay surface that splits a read-only scope out
  (paydeveloper.issuer.readonly).
