WHAT IT DOES

What retrieveOAuthScopeWithId does on Fusionauth

AI agents call retrieveOAuthScopeWithId to retrieve information from Fusionauth without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why retrieveOAuthScopeWithId is rated Low

The tool performs a query operation to fetch OAuth scope data without side effects. It does not create, modify, delete, or execute any operations—it only retrieves existing configuration data. This is a straightforward read operation with minimal risk if misused.

From the tool's definition Tool name contains 'retrieve' and description states 'Retrieves a custom OAuth scope' with no modification or execution of operations.
