AI agents use ppt_group_shapes 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.
This tool modifies presentation content by organizing shapes into a group, which is a standard presentation editing operation. It creates a new logical structure (grouping) but does not create new content, delete content, or execute arbitrary code. The operation is reversible—shapes can be ungrouped.
From the tool's definition Tool name 'ppt_group_shapes' and description 'Group multiple shapes into a single group' indicate a reversible modification operation that groups existing presentation elements.
Documented attack patterns abuse exactly the kind of access ppt_group_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_group_shapes:
{
"version": "1",
"default": "deny",
"tools": {
"ppt_group_shapes": {
"limits": [
{
"counter": "ppt_group_shapes_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}ppt_group_shapes 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.
Group multiple shapes into a single group. 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_group_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_group_shapes 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_group_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_group_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_group_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.
