AI agents use ppt_set_soft_edge 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 data by applying a formatting effect to a shape. It is reversible (soft edge can be removed or changed), making it Write rather than Destructive. It does not execute arbitrary code, delete data, or perform financial operations.
From the tool's definition ppt_set_soft_edge sets properties on a shape (soft edge effect); this modifies presentation content. The tool name indicates a property modification operation ('set'), and the server provides 'real-time control of Microsoft PowerPoint' for 'create and edit…
Documented attack patterns abuse exactly the kind of access ppt_set_soft_edge 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_set_soft_edge:
{
"version": "1",
"default": "deny",
"tools": {
"ppt_set_soft_edge": {
"limits": [
{
"counter": "ppt_set_soft_edge_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}ppt_set_soft_edge 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.
Set soft edge effect on a shape. 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_set_soft_edge: 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_set_soft_edge 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_set_soft_edge 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_set_soft_edge. 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_set_soft_edge 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.
