Why crow_campaign_approve_posts needs a policy

This tool creates or modifies data reversibly by changing post status from pending/draft to approved. The action is not destructive (posts are not deleted), not financial, and not execute (no arbitrary code/commands).

From the tool's definition Tool performs 'Batch approve posts by ID' and explicitly states posts are moved from 'pending_approval/draft to approved' — a state change that modifies data.

How to control crow_campaign_approve_posts

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 crow_campaign_approve_posts:

policy.json

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

crow_campaign_approve_posts 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.
