## Why list_logical_views is rated Low

This tool queries and returns information about logical views within a Bigtable instance. It performs a read-only operation with no side effects, matching the Read category definition of 'retrieves or queries data'. The severity is low because listing metadata poses minimal risk unless the metadata itself is highly sensitive, which is typical for standard resource enumeration.

From the tool's own definition: "Tool name contains 'list' and description states 'List information about all logical views' — a retrieval operation with no modification or deletion."

## Use case

AI agents call list_logical_views 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_logical_views": {}
  }
}
