AI agents call ppt_list_shapes 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.
This tool retrieves information about shapes present on a slide without creating, modifying, deleting, or executing any operations. It is a passive data retrieval function analogous to a 'list' or 'get' operation, which falls squarely into the Read category. The severity is low because misuse by an AI agent would only result in unwanted information disclosure, not side effects or damage to the presentation.
From the tool's definition Tool name 'ppt_list_shapes' and description 'List all shapes on a slide' indicate a query/retrieval operation with no modifications to the presentation.
Documented attack patterns abuse exactly the kind of access ppt_list_shapes gives an agent:
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_shapes:
{
"version": "1",
"default": "deny",
"tools": {
"ppt_list_shapes": {}
}
}ppt_list_shapes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all shapes on a slide. It is categorised as a Read tool in the Ppt MCP Server, which means it retrieves data without modifying state.
Register the Ppt MCP server in PolicyLayer and add a rule for ppt_list_shapes: 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 Ppt. Nothing to install.
ppt_list_shapes 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 ppt_list_shapes 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 ppt_list_shapes. 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.
ppt_list_shapes is provided by the Ppt MCP server (ykuwai/ppt-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
