What retrieveReportLogin does on Fusionauth
AI agents call retrieveReportLogin 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 retrieveReportLogin is rated Low
This tool queries historical login data for a user within a time range, optionally filtered by application. It performs no mutations, deletions, or external actions. The blast radius of misuse is limited to unauthorized information disclosure of login analytics, which is a read-based information exposure risk rather than a Write, Execute, Destructive, or Financial risk.
From the tool's definition Tool name and description use 'Retrieves' repeatedly. The description explicitly states it 'Retrieves the login report' and 'will only return the login counts' — purely query/fetch operations with no modifications, deletions, or side effects.
Attacks that exploit this kind of access
The rule that runs retrieveReportLogin 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 retrieveReportLogin, this is the rule to start with:
retrieveReportLogin 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 retrieveReportLogin call is checked against it from then on.
