Insert an image into a Google Slides slide from a publicly accessible URL
AI agents use insertSlidesImageFromUrl to create or update resources in Google Drive MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Google Drive MCP Server environment.
This tool creates or modifies presentation content by inserting images into slides. It is reversible (the image can be removed), so it falls under Write rather than Destructive. The blast radius is medium because unauthorized insertion of images could deface presentations, confuse audiences, or inject misleading visual content into shared documents, but the change is non-destructive and can be undone.
From the tool's definition Tool name includes 'insert' and description states 'Insert an image into a Google Slides slide from a publicly accessible URL', indicating creation/modification of slide content.

PolicyLayer is an MCP gateway — it sits between your AI agents and Google Drive MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for insertSlidesImageFromUrl:
{
"version": "1",
"default": "deny",
"tools": {
"insertSlidesImageFromUrl": {
"limits": [
{
"counter": "insertslidesimagefromurl_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}insertSlidesImageFromUrl 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.
