Adds a text box to a specific slide (dimensions in points).
AI agents use add_text_box to create or update resources in PowerPoint MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your PowerPoint MCP Server environment.
This tool creates new content (a text box) within a PowerPoint presentation in a reversible manner. It does not execute code, delete data, move money, or cause irreversible changes. It is a straightforward content creation operation, classifying it as Write with low severity since misuse would only result in unwanted text box additions that can be easily removed.
From the tool's definition Tool name 'add_text_box' and description 'Adds a text box to a specific slide' indicates creation of a new content element within a presentation document.
Documented attack patterns abuse exactly the kind of access add_text_box gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and PowerPoint MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for add_text_box:
{
"version": "1",
"default": "deny",
"tools": {
"add_text_box": {
"limits": [
{
"counter": "add_text_box_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_text_box 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.

Adds a text box to a specific slide (dimensions in points). It is categorised as a Write tool in the PowerPoint MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the PowerPoint MCP Server MCP server in PolicyLayer and add a rule for add_text_box: 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 PowerPoint MCP Server. Nothing to install.
add_text_box 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 add_text_box 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 add_text_box. 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.
add_text_box is provided by the PowerPoint MCP Server MCP server (jenstangen1/pptx-xlsx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from PowerPoint MCP Server, 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.
