Creates an approval request for a story (and optional release) in a Storyblok space.
AI agents use create_approval 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.
Creating an approval request is a reversible write operation that changes the state of a story's workflow within Storyblok—it creates a new approval entity but does not irreversibly delete, execute arbitrary code, or move money. The impact is limited to workflow management and can be undone or superseded by subsequent approvals or rejections.
From the tool's definition Tool name 'create_approval' and description 'Creates an approval request for a story (and optional release)' indicate a creation action that modifies workflow state by introducing an approval request.
Documented attack patterns abuse exactly the kind of access create_approval 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_approval:
{
"version": "1",
"default": "deny",
"tools": {
"create_approval": {
"limits": [
{
"counter": "create_approval_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_approval 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.

Creates an approval request for a story (and optional release) in a Storyblok space. 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_approval: 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_approval 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_approval 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_approval. 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_approval 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.
