Add a shape with text to a slide
AI agents use keynote_add_shape 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.
This tool creates new content (a shape) within an existing presentation slide, which is a reversible modification. It does not execute arbitrary code, delete data, or commit financial actions. It fits the Write category as it modifies a document by adding an element.
From the tool's definition Tool name 'keynote_add_shape' and description 'Add a shape with text to a slide' indicate the tool creates/modifies content within a presentation by adding a new shape object.
Documented attack patterns abuse exactly the kind of access keynote_add_shape 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 keynote_add_shape:
{
"version": "1",
"default": "deny",
"tools": {
"keynote_add_shape": {
"limits": [
{
"counter": "keynote_add_shape_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}keynote_add_shape 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.
Add a shape with text to a slide. 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 keynote_add_shape: 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.
keynote_add_shape 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 keynote_add_shape 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 keynote_add_shape. 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.
keynote_add_shape 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.
