WHAT IT DOES

What searchKeysWithId does on Fusionauth

AI agents call searchKeysWithId 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 searchKeysWithId is rated Low

This tool retrieves or queries data (API keys) based on search criteria. It is a Read operation that has no side effects. However, severity is elevated to medium rather than low because API keys are sensitive cryptographic credentials; exposure of search results could leak information about active keys or their metadata, even though the tool itself does not modify or delete them.

From the tool's definition Tool name contains 'search' and description states 'Searches keys with the specified criteria and pagination' — a query operation with no modifications.

RECOMMENDED RULE

The rule that runs searchKeysWithId 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 searchKeysWithId, this is the rule to start with:

searchKeysWithId Allowed

searchKeysWithId is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "searchKeysWithId": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Fusionauth, apply this rule, and every searchKeysWithId call is checked against it from then on.
