WHAT IT DOES

What add_hyperlink does on Docx

AI agents use add_hyperlink 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 add_hyperlink is rated Medium

Adding a hyperlink modifies the document structure and content reversibly—it creates a new element but can be undone or removed. This is a Write operation rather than Read (which would only retrieve data). It is not Destructive (hyperlinks can be deleted), not Execute (it doesn't run arbitrary code or commands), and not Financial.

From the tool's definition Tool name 'add_hyperlink' indicates modification of document content by inserting hyperlinks into a Word document.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_hyperlink 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 add_hyperlink, this is the rule to start with:

add_hyperlink Rate-limited

add_hyperlink 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 add_hyperlink call is checked against it from then on.
