What retrieveUserActionReason does on Fusionauth
AI agents call retrieveUserActionReason 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.
Why retrieveUserActionReason is rated Low
This is a straightforward data retrieval operation. It queries user action reason information without side effects. The blast radius is minimal—at worst an AI agent could enumerate user action reasons, which is a read-only information disclosure risk. No financial, destructive, or code-execution capability present.
From the tool's definition Tool retrieves user action reason data with 'Retrieves' explicitly stated in description; optional Id parameter returns either specific reason or all reasons if null passed; no modification, deletion, or execution implied.
Attacks that exploit this kind of access
The rule that runs retrieveUserActionReason safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Fusionauth, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For retrieveUserActionReason, this is the rule to start with:
retrieveUserActionReason is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Fusionauth, apply this rule, and every retrieveUserActionReason call is checked against it from then on.
