THE RISK

Low Risk

Why list_generated_v2_outputs needs a policy

This tool performs a directory listing operation to enumerate files in a specific output directory. It is a pure read operation with no capability to modify, delete, or execute code. The severity is low because even misuse would only expose file names and structure of generated outputs, which poses minimal security risk in the context of a migration assistant.

From the tool's definition Tool name 'list_generated_v2_outputs' and description 'Lists files present in data/generated after running the HeroUI v2 generator' explicitly indicate a read operation that retrieves/queries file listings with no side effects.

POLICY

How to control list_generated_v2_outputs

PolicyLayer is an MCP gateway — it sits between your AI agents and HeroUI Migration MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for list_generated_v2_outputs:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_generated_v2_outputs": {}
  }
}

list_generated_v2_outputs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register HeroUI Migration MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about list_generated_v2_outputs

What does the list_generated_v2_outputs tool do? +

Lists files present in data/generated after running the HeroUI v2 generator. It is categorised as a Read tool in the HeroUI Migration MCP MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list_generated_v2_outputs? +

Register the HeroUI Migration MCP server in PolicyLayer and add a rule for list_generated_v2_outputs: 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 HeroUI Migration MCP. Nothing to install.

What risk level is list_generated_v2_outputs? +

list_generated_v2_outputs is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list_generated_v2_outputs? +

Yes. Add a rate_limit block to the list_generated_v2_outputs 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.

How do I block list_generated_v2_outputs completely? +

Set action: deny in the PolicyLayer policy for list_generated_v2_outputs. 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.

What MCP server provides list_generated_v2_outputs? +

list_generated_v2_outputs is provided by the HeroUI Migration MCP server (sctg-development/heroui-migration-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every HeroUI Migration MCP tool call.

Start from HeroUI Migration MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
