Create a draft post for a campaign targeting a specific subreddit.
AI agents use crow_campaign_draft_post to create or update resources in Crow — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Crow environment.
This tool creates a draft social media post, which is a reversible write operation. While it generates content for a specific campaign targeting a subreddit, the draft status means it has not yet been published or committed to the platform, and can be edited or discarded. This makes it Write rather than Execute (which would apply to publishing/posting) or Destructive.
From the tool's definition Tool name includes 'draft_post' and description states 'Create a draft post' — indicating creation of content that can be modified or deleted before publication.

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_draft_post:
{
"version": "1",
"default": "deny",
"tools": {
"crow_campaign_draft_post": {
"limits": [
{
"counter": "crow_campaign_draft_post_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}crow_campaign_draft_post 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.
