What wp_create_tag does on Wordpress
AI agents use wp_create_tag to create or update resources in Wordpress, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Wordpress environment.
Why wp_create_tag is rated Medium
Creating a tag modifies WordPress data structure by adding a new taxonomy term. This is reversible (tags can be deleted), so it falls under Write rather than Destructive. However, it carries medium severity because careless or malicious tag creation could pollute the taxonomy, affect site navigation/organization, and potentially be used in conjunction with posts to manipulate content visibility or SEO.
From the tool's definition Tool name is 'wp_create_tag' with description 'Create a new tag' — the verb 'create' and description explicitly indicate data creation/addition to the WordPress system.
Attacks that exploit this kind of access
The rule that runs wp_create_tag safely

wp_create_tag 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 Wordpress, apply this rule, and every wp_create_tag call is checked against it from then on.
