Why crow_campaign_publish_post needs a policy

Publishing a post to Reddit is an external operation with real-world side effects — it posts publicly visible content to a third-party platform. This is not purely a Write to a local/internal system; it triggers an external action. The blast radius is high because a misuse could publish unintended or harmful content publicly on Reddit under the user's account.

From the tool's definition Immediately publish a single post to Reddit. Requires confirmation.

How to control crow_campaign_publish_post

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_publish_post:

policy.json

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

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