AI agents use ppt_add_comment to create or update resources in Ppt — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ppt environment.
Adding a comment creates new data (the comment itself) within the presentation but does not delete, overwrite, execute code, move money, or trigger external side effects. This is a typical Write operation: reversible, non-destructive modification of presentation content.
From the tool's definition Tool description states 'Add a comment to a slide' — a comment is metadata attached to content that can be modified or deleted, representing a reversible change to the presentation.
Documented attack patterns abuse exactly the kind of access ppt_add_comment 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_add_comment:
{
"version": "1",
"default": "deny",
"tools": {
"ppt_add_comment": {
"limits": [
{
"counter": "ppt_add_comment_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}ppt_add_comment stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Add a comment to a slide. It is categorised as a Write tool in the Ppt MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Ppt MCP server in PolicyLayer and add a rule for ppt_add_comment: 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_add_comment is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the ppt_add_comment 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_add_comment. 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_add_comment 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.
