AI agents use create_release 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.
The tool creates a new entity (release) in the CMS, which is a Write-category operation. Severity is medium because: (1) the description is empty, reducing confidence slightly, (2) creating releases typically does not immediately affect production content unless explicitly published, and (3) releases are usually reversible.
From the tool's definition Tool name 'create_release' implies creating a new release object/version in Storyblok CMS. Sibling tools include 'add_story_to_release' and 'backup_space', confirming this server manages content releases.
Documented attack patterns abuse exactly the kind of access create_release gives an agent:
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 create_release:
{
"version": "1",
"default": "deny",
"tools": {
"create_release": {
"limits": [
{
"counter": "create_release_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_release 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.

create_release. It is categorised as a Write tool in the Storyblok MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Storyblok MCP Server MCP server in PolicyLayer and add a rule for create_release: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Storyblok MCP Server. Nothing to install.
create_release is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_release rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for create_release. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
create_release is provided by the Storyblok MCP Server MCP server (arjuncodess/storyblok-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Storyblok MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
