Lists the node pools for a specific GKE cluster.

Agent View of the PolicyLayer registry record for `list_node_pools`. HTML page: https://policylayer.com/tools/com-googleapis-container-mcp/list-node-pools

## Facts

- Tool: `list_node_pools`
- Server: Mcp (`https://container.googleapis.com/mcp`) — https://policylayer.com/tools/com-googleapis-container-mcp.md
- Homepage: https://github.com/https://container.googleapis.com/mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server auth posture: open
- Server rate-limited: no
- Parameters: 1 (1 required)
- Recommended policy verdict: Allowed

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `parent` | string | yes | Required. The parent (project, location, cluster name) where the node pools will be listed. Specified in the format `projects/*/locations/*/clusters/*`. |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "list_node_pools",
    "arguments": {
      "parent": "<parent>"
    }
  }
}
```

## Why list_node_pools is rated Low

The tool retrieves and lists existing node pool information for a GKE cluster. This is a read-only operation with no capability to modify infrastructure, delete resources, or execute commands. While the information returned could potentially inform an attacker about cluster topology, the tool itself poses minimal direct risk without additional malicious tools in the chain.

From the tool's own definition: "Tool name 'list_node_pools' and description 'Lists the node pools' indicate a query/retrieval operation with no side effects."

## Use case

AI agents call list_node_pools to retrieve information from Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Mcp:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_node_pools": {}
  }
}
```
