WHAT IT DOES

What update_webhook does on Storyblok MCP Server

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

RISK

Why update_webhook is rated Medium

The tool modifies webhook configurations, which are integral to CMS operations and can control external integrations. While reversible (Write rather than Destructive), misconfiguration could disrupt critical workflows or redirect data flows to unintended endpoints, warranting high severity.

From the tool's definition Tool is named 'update_webhook' and exists within Storyblok CMS server context. Webhooks are configuration objects that trigger external actions. 'Update' indicates modification of existing webhook configuration, which is a reversible data change.
