Insert a floating (anchored) image. wrap: square|topbottom|none.
AI agents use insert_floating_image to create or update resources in Docx — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Docx environment.
This tool creates new content in a Word document by inserting an image, which is a reversible modification operation. It does not execute code, delete data, or move money. While it modifies document structure, the change can be undone. Severity is medium because inserting unintended images could deface documents or introduce unwanted content, but the effects are non-destructive and reversible.
From the tool's definition Tool name 'insert_floating_image' combined with description indicating it inserts images into a document. Related sibling tools like 'add_comment', 'add_bookmark', 'add_equation' are all document modification operations.
Documented attack patterns abuse exactly the kind of access insert_floating_image gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Docx, and nothing reaches the server without passing your rules. This is the rule we recommend for insert_floating_image:
{
"version": "1",
"default": "deny",
"tools": {
"insert_floating_image": {
"limits": [
{
"counter": "insert_floating_image_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}insert_floating_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.

Insert a floating (anchored) image. wrap: square|topbottom|none. It is categorised as a Write tool in the Docx MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Docx MCP server in PolicyLayer and add a rule for insert_floating_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 Docx. Nothing to install.
insert_floating_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 insert_floating_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 insert_floating_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.
insert_floating_image is provided by the Docx MCP server (securityronin/docx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Docx, 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.
