WHAT IT DOES

What set_image_border does on Docx

AI agents use set_image_border 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 set_image_border is rated Medium

The tool modifies document structure/formatting by altering image properties, which is reversible and does not delete data or execute arbitrary code. This aligns with the Write category. Severity is medium because formatting changes could affect document appearance or layout unexpectedly, but lack of description reduces confidence. The reversible nature (borders can be removed) and focused scope keep it below high.

From the tool's definition Tool name 'set_image_border' indicates modification of document properties (image formatting). Server description emphasizes 'editing' Microsoft Word documents and 'OOXML-level document manipulation'.

set_image_border Rate-limited

set_image_border 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.
