What list_huly_enums does on Huly
AI agents call list_huly_enums to retrieve information from Huly without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_huly_enums is rated Low
This tool retrieves and displays enum definitions and their permitted values from the Huly system. It is explicitly designed for inspection and discovery purposes prior to write operations, making it a read operation with no capability to modify, delete, or execute code. The low severity reflects minimal blast radius even if misused by an agent.
From the tool's definition Tool description states 'Discover Huly enum model documents and their valid values' and 'inspect allowed enum values' — purely informational retrieval with no side effects. The verb 'list' and 'discover' indicate read-only data inspection.
Attacks that exploit this kind of access
The rule that runs list_huly_enums safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Huly, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_huly_enums, this is the rule to start with:
list_huly_enums 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 Huly, apply this rule, and every list_huly_enums call is checked against it from then on.

Register the Huly MCP server in PolicyLayer and add a rule for list_huly_enums: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Huly. Nothing to install.
list_huly_enums is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_huly_enums rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for list_huly_enums. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
