What get_huly_class does on Huly
AI agents call get_huly_class 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 get_huly_class is rated Low
This tool queries and retrieves metadata about Huly classes—their inheritance hierarchy and attributes—without modifying, executing, or deleting anything. It is purely informational/introspective in nature. The low severity reflects that misuse would only expose internal schema information, which could inform an attack but does not directly compromise data or systems.
From the tool's definition Tool description explicitly states 'Read one Huly class/interface/mixin by exact ID and return its inheritance chain plus model attributes.' The verb 'Read' and the action of retrieving/returning metadata and structure information with no side effects are…
Attacks that exploit this kind of access
The rule that runs get_huly_class 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 get_huly_class, this is the rule to start with:
get_huly_class 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 get_huly_class call is checked against it from then on.

Read one Huly class/interface/mixin by exact ID and return its inheritance chain plus model attributes. Use this when you need fields, ref targets, enum IDs, or hints about purpose-built MCP tool categories for the class. It is categorised as a Read tool in the Huly MCP Server, which means it retrieves data without modifying state.
Register the Huly MCP server in PolicyLayer and add a rule for get_huly_class: 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.
get_huly_class 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 get_huly_class 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 get_huly_class. 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.
get_huly_class is provided by the Huly MCP server (@firfi/huly-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
