WHAT IT DOES

What add_internal_link does on Docx

AI agents use add_internal_link 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_internal_link is rated Medium

Adding an internal link to a document is a reversible write operation that modifies document content but does not delete or execute arbitrary code. The empty description lowers confidence slightly, but the name and context from sibling tools strongly indicate this is a document modification (Write) rather than read, execute, or destructive.

From the tool's definition Tool name 'add_internal_link' indicates creation of a document element. Server description states it enables 'editing' of Word documents and 'OOXML-level document manipulation.' Sibling tools like 'add_comment', 'add_bookmark', 'add_content_control' are all…

Attacks that exploit this kind of access

RECOMMENDED RULE

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

add_internal_link Rate-limited

add_internal_link 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_internal_link call is checked against it from then on.
