WHAT IT DOES

What cms_create_entry does on Munin

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

RISK

Why cms_create_entry is rated Medium

This tool creates new content/data entries in a CMS collection, which is a reversible write operation. It does not execute arbitrary code, delete data, move money, or retrieve data. The severity is medium because malicious use could spam or pollute content, but entries can typically be edited or deleted afterward. Confidence is high because the description clearly indicates content creation.

From the tool's definition Tool name is `cms_create_entry` and description states 'Create a new entry in a collection.' The verb 'Create' and explicit mention of creating entries indicates data modification.
