RISK

Why update_datasource is rated Medium

The 'update_' prefix strongly suggests this tool modifies existing data in Storyblok's datasource system reversibly. This aligns with the Write category (creates or modifies data reversibly). Severity is medium because datasource updates in a CMS could affect content rendering and dependencies, but are typically reversible.

From the tool's definition Tool named 'update_datasource' on a content management system (Storyblok CMS). The 'update_' prefix indicates modification of data. No description provided, so classification relies on naming convention and server context.

update_datasource Rate-limited
