List all available Numbers templates (e.g. Personal Budget, Invoice, Checklist)
AI agents call numbers_list_templates to retrieve information from Iwork without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries and returns a list of pre-built templates available in Apple Numbers. This is a read-only operation that retrieves information without creating, modifying, deleting, or executing any data changes. No code execution or external operations are triggered. The blast radius of misuse is minimal — an attacker could only learn what templates exist, which is not sensitive information.
From the tool's definition Tool name is 'numbers_list_templates' and description states it 'List all available Numbers templates' — this is a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access numbers_list_templates gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Iwork, and nothing reaches the server without passing your rules. This is the rule we recommend for numbers_list_templates:
{
"version": "1",
"default": "deny",
"tools": {
"numbers_list_templates": {}
}
}numbers_list_templates is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Iwork MCP server in PolicyLayer and add a rule for numbers_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 Iwork. Nothing to install.
numbers_list_templates 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 numbers_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.
Set action: deny in the PolicyLayer policy for numbers_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.
numbers_list_templates is provided by the Iwork MCP server (reichenbach/iwork_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Iwork, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
