Why immich_create_album needs a policy

This tool creates a new album resource in Immich (a photo management service), which is a reversible write operation. It does not delete data (Destructive), execute arbitrary code (Execute), involve financial transactions (Financial), or involve monetary movement. The blast radius is low since creating an album is a standard, benign operation with no cascading side effects or data loss risk.

From the tool's definition Tool name includes 'create' and description states 'Create a new photo album', indicating creation of new data structures.

POLICY

How to control immich_create_album

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

policy.json

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

immich_create_album 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 Crow — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
