Create a post. If collection is omitted, the post is a draft (anonymous post, not federated until published to a collection). Rate-limited: 10/hour.
AI agents use wf_create_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 new content (posts) in the project management system. Creation of data is a Write operation—it modifies the system state by adding new records, but the action is reversible (posts can be deleted). It is not Destructive (irreversible deletion), not Execute (does not run arbitrary code), and not Financial.
From the tool's definition Tool name 'wf_create_post' and description 'Create a post' indicates it creates new data. The note about drafts vs. published posts shows the creation is reversible (posts can be deleted/unpublished).
Documented attack patterns abuse exactly the kind of access wf_create_post gives an agent:
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 wf_create_post:
{
"version": "1",
"default": "deny",
"tools": {
"wf_create_post": {
"limits": [
{
"counter": "wf_create_post_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}wf_create_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.

Create a post. If collection is omitted, the post is a draft (anonymous post, not federated until published to a collection). Rate-limited: 10/hour. It is categorised as a Write tool in the Crow MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Crow MCP server in PolicyLayer and add a rule for wf_create_post: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Crow. Nothing to install.
wf_create_post is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the wf_create_post rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for wf_create_post. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
wf_create_post is provided by the Crow MCP server (kh0pper/crow). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Crow, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
