AI agents use ppt_remove_hyperlink 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.
Removing a hyperlink modifies the presentation by deleting a link attribute from a shape, but this is a reversible change (the hyperlink can be re-added). It does not delete content, run code, or have financial implications. Classified as Write due to its reversible modification nature, with low severity since it only affects a hyperlink property on a shape.

Documented attack patterns abuse exactly the kind of access ppt_remove_hyperlink 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_remove_hyperlink:
{
"version": "1",
"default": "deny",
"tools": {
"ppt_remove_hyperlink": {
"limits": [
{
"counter": "ppt_remove_hyperlink_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}ppt_remove_hyperlink 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.

Remove a hyperlink from 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_remove_hyperlink: 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_remove_hyperlink 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_remove_hyperlink 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_remove_hyperlink. 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_remove_hyperlink 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.
