Why create_branch_deployment needs a policy

This tool triggers an external deployment operation — pushing releases to a pipeline stage. This is an Execute category action as it initiates an external process whose effects depend on the arguments (which releases, which branch). Deployments can have significant blast radius if misused (e.g., deploying wrong content to production), hence high severity.

From the tool's definition Triggers a deployment of specified releases to a given branch (pipeline stage)

POLICY

How to control create_branch_deployment

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_branch_deployment:

policy.json

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

create_branch_deployment 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.

FAQ

Questions about create_branch_deployment

What does the create_branch_deployment tool do? +

Triggers a deployment of specified releases to a given branch (pipeline stage). It is categorised as a Execute tool in the Storyblok MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on create_branch_deployment? +

Register the Storyblok MCP Server MCP server in PolicyLayer and add a rule for create_branch_deployment: 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 create_branch_deployment? +

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

Can I rate-limit create_branch_deployment? +

Yes. Add a rate_limit block to the create_branch_deployment 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 create_branch_deployment completely? +

Set action: deny in the PolicyLayer policy for create_branch_deployment. 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 create_branch_deployment? +

create_branch_deployment 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.
