Create a new article in a knowledge base collection. For multilingual pairs, create the first language version (pair_id auto-generated), then create the translation with the same pair_id.
AI agents use crow_kb_create_article 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 knowledge base articles, which is a reversible write operation. Articles can be updated or deleted later, so this is not Destructive. The operation involves creating data in a persistent system (the knowledge base), which could impact project management workflows if abused (e.g., flooding with spam articles, corrupting knowledge bases).
From the tool's definition Tool description explicitly states 'Create a new article' - the verb 'create' is characteristic of Write operations that reversibly add data to a system.
Documented attack patterns abuse exactly the kind of access crow_kb_create_article 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 crow_kb_create_article:
{
"version": "1",
"default": "deny",
"tools": {
"crow_kb_create_article": {
"limits": [
{
"counter": "crow_kb_create_article_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}crow_kb_create_article 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 new article in a knowledge base collection. For multilingual pairs, create the first language version (pair_id auto-generated), then create the translation with the same pair_id. 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 crow_kb_create_article: 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.
crow_kb_create_article 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 crow_kb_create_article 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 crow_kb_create_article. 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.
crow_kb_create_article 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.
