WHAT IT DOES

What snapshot_list does on Uefn

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

RISK

Why snapshot_list is rated Low

This tool retrieves metadata about existing snapshots without creating, modifying, deleting, or executing any actions. It is a pure read operation with minimal blast radius—the worst outcome is information disclosure about available snapshots.

From the tool's definition Tool name 'snapshot_list' and description 'List all available level snapshots' indicate a query/retrieval operation with no modification, deletion, or execution of code.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs snapshot_list safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Uefn, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For snapshot_list, this is the rule to start with:

snapshot_list Allowed

snapshot_list 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": {
    "snapshot_list": {}
  }
}

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

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