article_update · Voog MCP: Risk & Policy

WHAT IT DOES

What article_update does on Voog

AI agents use article_update to create or update resources in Voog — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Voog environment.

WHY IT NEEDS A POLICY

Why article_update needs a policy

This tool creates or modifies data reversibly by updating article fields. It is not destructive (does not delete), not financial, not executable code. The incomplete description ('go to') suggests field mapping but does not alter the classification. Severity is medium because unintended article updates could impact published content, SEO, or user-facing pages, but changes can typically be reverted.

From the tool's definition Tool name 'article_update' and description 'Update an existing article. Title/body/excerpt go to' explicitly indicate modification of article data (title, body, excerpt fields).

Verdict

article_update Rate-limited

article_update 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.
