Why list_templates needs a policy

This tool retrieves and enumerates available templates without creating, modifying, deleting, or executing anything. It is a pure read operation with minimal blast radius if misused.

From the tool's definition Tool name 'list_templates' and description 'List available O3DE project and gem templates' indicate a retrieval operation with no side effects.

POLICY

How to control list_templates

PolicyLayer is an MCP gateway — it sits between your AI agents and O3de, and nothing reaches the server without passing your rules. This is the rule we recommend for list_templates:

policy.json

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

list_templates 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 O3de — 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_templates

What does the list_templates tool do? +

List available O3DE project and gem templates. It is categorised as a Read tool in the O3de MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on list_templates? +

Register the O3de MCP server in PolicyLayer and add a rule for list_templates: 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 O3de. Nothing to install.

What risk level is list_templates? +

Can I rate-limit list_templates? +

Yes. Add a rate_limit block to the list_templates 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_templates completely? +

Set action: deny in the PolicyLayer policy for list_templates. 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_templates? +

list_templates is provided by the O3de MCP server (nickschuetz/o3de-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every O3de tool call.

Start from O3de, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
