AI agents use ppt_export_shape 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 creates/outputs new data (an image file) but does not delete or irreversibly modify existing content. It is reversible—exported files can be deleted or overwritten. The blast radius is moderate: an agent could export many files, consume disk space, or generate unintended images, but cannot destroy data or execute arbitrary code.
From the tool's definition Tool exports (writes/saves) a shape as an image file, creating new file data on disk. Description uses 'export' which implies creation of an output artifact.
Documented attack patterns abuse exactly the kind of access ppt_export_shape 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_export_shape:
{
"version": "1",
"default": "deny",
"tools": {
"ppt_export_shape": {
"limits": [
{
"counter": "ppt_export_shape_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}ppt_export_shape 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.
Export a shape as an image file. 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_export_shape: 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_export_shape 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_export_shape 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_export_shape. 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_export_shape 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.
