## Why bigquery_list_datasets is rated Low

This tool performs a data retrieval operation (listing datasets) with no side effects, no data modification, and no triggering of external operations. It is purely informational. The blast radius of misuse is limited to potential information disclosure about available datasets in a GCP project.

From the tool's own definition: "Tool name 'bigquery_list_datasets' and description 'List the datasets in a GCP project visible to a BigQuery connection' both indicate a read-only query operation that retrieves information without modifying data."

## Use case

AI agents call bigquery_list_datasets to retrieve information from Deloc 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 Deloc:

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