What searchApplicationsWithId does on Fusionauth
AI agents call searchApplicationsWithId 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 searchApplicationsWithId is rated Low
This is a search operation that retrieves application data based on criteria. It performs no modifications, deletions, or external operations—purely a read-only query operation. The pagination parameters and search criteria are standard read-operation attributes. Blast radius is minimal as misuse would only expose or over-query existing application metadata.
From the tool's definition Tool name 'searchApplicationsWithId' and description 'Searches applications with the specified criteria and pagination' indicate a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
The rule that runs searchApplicationsWithId 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 searchApplicationsWithId, this is the rule to start with:
searchApplicationsWithId 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 searchApplicationsWithId call is checked against it from then on.
