THE RISK

Medium Risk

Why create_folder needs a policy

The tool creates new data (a folder) in the user's Discogs collection, which is a reversible write operation. It does not execute arbitrary code, delete data irreversibly, or involve financial transactions. The blast radius is minimal—a misused AI could create unwanted folders, but this is easily undone by deleting them (as evidenced by the 'delete_folder' sibling tool).

From the tool's definition Tool name 'create_folder' and description 'Create a new folder in your Discogs collection' indicate creation of a new organizational container. This is a write operation that modifies the collection structure by adding a new folder.

POLICY

How to control create_folder

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

policy.json

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

create_folder 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.

Create a free account and register Discogs 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.
