AI agents use ppt_modify_smartart 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.
The tool name 'modify' combined with the server's purpose (PowerPoint editing) indicates this tool creates or modifies presentation content reversibly. While the description is empty, reducing confidence slightly, the naming convention and context of sibling tools (all Write operations) strongly suggest this falls under Write rather than Execute or Destructive.
From the tool's definition Tool name 'ppt_modify_smartart' indicates modification of SmartArt objects in PowerPoint; 'modify' suggests altering existing content reversibly.

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_modify_smartart:
{
"version": "1",
"default": "deny",
"tools": {
"ppt_modify_smartart": {
"limits": [
{
"counter": "ppt_modify_smartart_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}ppt_modify_smartart 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_modify_smartart. 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_modify_smartart: 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_modify_smartart 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_modify_smartart 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_modify_smartart. 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_modify_smartart 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.
