Why CheckNetworkSecurity needs a policy

The description is empty and uninformative. The name 'CheckNetworkSecurity' suggests a read/audit operation (checking security posture), but it could also trigger active scans or make configuration changes. Given the context of an AWS Bedrock Knowledge Base Retrieval server, it seems out of place. With no description, confidence is low.

From the tool's definition Tool name 'CheckNetworkSecurity' and empty description provide no detail about what the tool does.

POLICY

How to control CheckNetworkSecurity

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Bedrock Knowledge Base Retrieval MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for CheckNetworkSecurity:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "CheckNetworkSecurity": {
      "limits": [
        {
          "counter": "checknetworksecurity_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

CheckNetworkSecurity gets a rate cap, and everything else on the server is denied unless you say otherwise.
