Updates multiple stories in Storyblok, optionally publishing them.
AI agents use bulk_update_stories 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.
This tool modifies content (stories) in a CMS system reversibly—updates can be undone or reverted. While it can publish stories (making changes public/permanent), the core operation is Write rather than Destructive since updates are not irreversible deletions.
From the tool's definition Tool description states 'Updates multiple stories in Storyblok, optionally publishing them.' The verb 'Updates' indicates modification of existing data. The 'bulk_' prefix and 'multiple stories' phrase indicate this affects many records at once.

PolicyLayer is an MCP gateway — it sits between your AI agents and Storyblok MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for bulk_update_stories:
{
"version": "1",
"default": "deny",
"tools": {
"bulk_update_stories": {
"limits": [
{
"counter": "bulk_update_stories_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}bulk_update_stories 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.
