AI agents use add_field 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.

Why add_field is rated Medium

Fields in Word documents are structural elements that can be inserted, modified, and removed. This is a reversible Write operation—not Read (no retrieval), not Execute (not running arbitrary code/commands), and not Destructive (insertion is undoable). Confidence is slightly reduced due to the empty description, but the naming pattern and server purpose strongly indicate a Write categorization.

From the tool's definition Tool name 'add_field' suggests adding or inserting a field element into a Word document. Sibling tools like 'add_bookmark', 'add_comment', 'add_content_control', 'add_cross_reference', 'add_endnote', and 'add_equation' all perform Write operations…
