Why create_structured_prompt needs a policy

This tool creates new prompts with metadata, which is a reversible Write operation. The 'structured' qualifier and 'guided metadata' suggest it enforces a schema rather than executing arbitrary operations. There is no indication it deletes, executes code, or commits financial obligations. Severity is low because misuse would only add unwanted prompt records that can be deleted; the blast radius is minimal.

From the tool's definition Tool name 'create_structured_prompt' and description 'Create a new prompt' indicate data creation. The word 'Create' is a classic Write operation that adds new records without irreversible deletion or side effects.

POLICY

How to control create_structured_prompt

PolicyLayer is an MCP gateway — it sits between your AI agents and Smart Prompts MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_structured_prompt:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_structured_prompt": {
      "limits": [
        {
          "counter": "create_structured_prompt_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_structured_prompt 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.

Point your MCP client (Claude, Cursor, anything) at your gateway URL.
