Why create_knowledge_from_url needs a policy

This tool creates new knowledge entries from external URL sources, which modifies the knowledge base by adding new content. This is a Write operation (reversible via delete_knowledge) rather than Read (it creates, not retrieves), Execute (no arbitrary command execution), Destructive (deletion is separate), or Financial (no financial impact).

From the tool's definition Tool name 'create_knowledge_from_url' and description 'Create knowledge from URL' indicate creation of new data resources within the knowledge management system.

POLICY

How to control create_knowledge_from_url

PolicyLayer is an MCP gateway — it sits between your AI agents and WeKnora MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_knowledge_from_url:

policy.json

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

create_knowledge_from_url 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.
