THE RISK

Why backup_space needs a policy

The tool triggers an external operation (a backup task) via an API. It does not delete or modify data, nor does it simply read data — it initiates a process with side effects on the Storyblok platform. This fits Execute as it triggers an external operation whose effects depend on arguments.

From the tool's definition 'Triggers a backup task for a Storyblok space using Management API'

POLICY

How to control backup_space

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 backup_space:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "backup_space": {
      "limits": [
        {
          "counter": "backup_space_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

backup_space stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Storyblok MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on backup_space? +

Register the Storyblok MCP Server MCP server in PolicyLayer and add a rule for backup_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.

What risk level is backup_space? +

backup_space is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit backup_space? +

Yes. Add a rate_limit block to the backup_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.

How do I block backup_space completely? +

Set action: deny in the PolicyLayer policy for backup_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.

What MCP server provides backup_space? +

backup_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.

Enforce policy on every Storyblok MCP Server tool call.

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.
