Why CheckNetworkSecurity needs a policy

The name suggests a read/audit operation (checking security configurations), which would typically be a Read category. However, with no description available, it's unclear whether this tool only reads network security settings or potentially modifies them. Given the 'Check' prefix strongly implies a read/audit action, Read would be the most likely category, but the empty description significantly lowers confidence.

From the tool's definition Tool name is 'CheckNetworkSecurity'; description is empty and uninformative.

POLICY

How to control CheckNetworkSecurity

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Data Processing 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
