AI agents call ppt_list_designs 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 and enumerates existing slide design templates from a presentation. It performs a passive read operation analogous to 'list' or 'get', returning information without altering any data. The blast radius of misuse is minimal—an AI agent cannot cause harm by listing designs. It should not be confused with tools that modify or create designs, which would fall into the Write category.
From the tool's definition Tool name 'ppt_list_designs' and description 'List all designs (slide masters) in the presentation' indicate a query/retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access ppt_list_designs 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_designs:
{
"version": "1",
"default": "deny",
"tools": {
"ppt_list_designs": {}
}
}ppt_list_designs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all designs (slide masters) in the presentation. 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_designs: 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_designs 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_designs 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_designs. 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_designs 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.
