AI agents call ppt_list_presentations 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 performs a read-only operation to enumerate open presentations. It has no side effects, does not modify data, and poses minimal security risk. The only potential concern is information disclosure (learning what presentations are open), which is low severity in most contexts.
From the tool's definition Tool name 'ppt_list_presentations' and description 'List all currently open presentations in PowerPoint' indicate a query operation that retrieves information without modification.

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_presentations:
{
"version": "1",
"default": "deny",
"tools": {
"ppt_list_presentations": {}
}
}ppt_list_presentations is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all currently open presentations in PowerPoint. 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_presentations: 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_presentations 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_presentations 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_presentations. 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_presentations 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.
