AI agents use ppt_format_connector 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.
Formatting a connector modifies presentation content reversibly—changes can be undone, and no data is deleted or destroyed. This qualifies as Write rather than Read (which retrieves data without side effects) or Destructive (which irreversibly deletes data). The severity is medium because misuse could degrade presentation quality or structure, but formatting changes are non-fatal and reversible.
From the tool's definition Tool name 'ppt_format_connector' indicates formatting (modifying visual properties) of connector objects in PowerPoint presentations. Part of a broader suite that enables creation and editing of presentations via COM automation.
Documented attack patterns abuse exactly the kind of access ppt_format_connector 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_format_connector:
{
"version": "1",
"default": "deny",
"tools": {
"ppt_format_connector": {
"limits": [
{
"counter": "ppt_format_connector_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}ppt_format_connector 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.

ppt_format_connector. 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_format_connector: 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_format_connector 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_format_connector 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_format_connector. 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_format_connector 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.
