Don't paste the token.
Compare the contract.

Load an OpenAPI JSON document locally, name the operations this client actually calls, and paste scope names—not a token. The tool compares only declared OAuth/OpenID requirements and surfaces missing declarations, missing grant names and possible excess for human review.
