Duplicates an existing Storyblok space via the Management API.
AI agents use duplicate_space 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.
Duplicating a space creates a new copy of an existing space, including all its content, components, and settings. This is a Write operation (creates new data) rather than Destructive (nothing is deleted). However, severity is high because it replicates an entire space which could include large amounts of content, assets, and configurations, and misuse could lead to unintended space proliferation or quota exhaustion.
From the tool's definition Duplicates an existing Storyblok space via the Management API
Documented attack patterns abuse exactly the kind of access duplicate_space 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 duplicate_space:
{
"version": "1",
"default": "deny",
"tools": {
"duplicate_space": {
"limits": [
{
"counter": "duplicate_space_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}duplicate_space 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.

Duplicates an existing Storyblok space via the Management API. 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 duplicate_space: 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.
duplicate_space 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 duplicate_space 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 duplicate_space. 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.
duplicate_space is provided by the Storyblok MCP Server MCP server (kiran1689/storyblok-mcp-server). 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.
Free to start. No card required.
