WHAT IT DOES

What insert_image does on Docx

AI agents use insert_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.

RISK

Why insert_image is rated Medium

Inserting an image modifies the document content in a reversible manner—the change can be undone or the document reverted. This is a Write operation. Severity is medium rather than low because uncontrolled image insertion could bloat documents, introduce malicious content, or degrade document integrity if an agent inserts many large images.

From the tool's definition Tool name 'insert_image' and description 'Insert an image into a document' indicate modification of document content.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs insert_image safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Docx, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For insert_image, this is the rule to start with:

insert_image Rate-limited

insert_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.

The button opens the PolicyLayer dashboard: create your workspace, connect Docx, apply this rule, and every insert_image call is checked against it from then on.
