AI agents call ppt_list_templates to retrieve information from Ppt without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list' prefix strongly suggests a query operation that retrieves or enumerates existing templates. No side effects (creation, deletion, modification, or code execution) are implied. Even if the tool returned template metadata or paths, this remains a non-destructive read operation. Low severity because listing templates poses minimal risk to presentations or system state.
From the tool's definition Tool name 'ppt_list_templates' with 'list' verb indicates retrieval of available PowerPoint templates without modification. Description is empty, reducing confidence moderately.

PolicyLayer is an MCP gateway — it sits between your AI agents and Ppt, and nothing reaches the server without passing your rules. This is the rule we recommend for ppt_list_templates:
{
"version": "1",
"default": "deny",
"tools": {
"ppt_list_templates": {}
}
}ppt_list_templates is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
