Insert an image into the document
AI agents use pages_add_image to create or update resources in Iwork — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Iwork environment.
The tool adds an image to a Pages document, which is a create/modify operation. This is reversible (images can be deleted or replaced), so it falls under Write rather than Destructive or Execute. Severity is medium because uncontrolled image insertion could bloat documents, deface content, or introduce malicious images, but the impact is bounded to a single document and reversible.
From the tool's definition Tool name is 'pages_add_image' and description states 'Insert an image into the document' — this creates or modifies document content reversibly.
Documented attack patterns abuse exactly the kind of access pages_add_image gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Iwork, and nothing reaches the server without passing your rules. This is the rule we recommend for pages_add_image:
{
"version": "1",
"default": "deny",
"tools": {
"pages_add_image": {
"limits": [
{
"counter": "pages_add_image_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}pages_add_image 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.
Insert an image into the document. It is categorised as a Write tool in the Iwork MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Iwork MCP server in PolicyLayer and add a rule for pages_add_image: 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 Iwork. Nothing to install.
pages_add_image 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 pages_add_image 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 pages_add_image. 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.
pages_add_image is provided by the Iwork MCP server (reichenbach/iwork_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Iwork, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
