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

```json
{
  "jsonrpc": "2.0",

  "params": {
    "name": "gcp_storage_list_objects",
    "arguments": {}

## Why gcp_storage_list_objects is rated Low

This tool performs a read-only operation—listing bucket contents. It has no side effects, does not create, modify, or delete resources, and does not execute code or trigger external operations. The blast radius is low since it only exposes metadata about existing objects.

From the tool's own definition: "Tool name 'gcp_storage_list_objects' and description 'List objects in a Cloud Storage bucket' indicate a query operation that retrieves or enumerates data without modification."

## Use case

AI agents call gcp_storage_list_objects to retrieve information from GCP MCP Server 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 GCP MCP Server:

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