## Why list_snapshots is rated Low

This tool performs a read-only query of Lightroom Classic's snapshot history for inspection purposes. There is no data modification, deletion, code execution, or financial impact. The blast radius of misuse is minimal—an agent could only enumerate snapshots, which poses no risk to the photo catalog or editing state.

From the tool's own definition: "Tool name 'list_snapshots' and description 'List develop snapshots for the active photo' indicate a retrieval operation with no side effects. It queries existing snapshot metadata without creating, modifying, or deleting data."

## Use case

AI agents call list_snapshots to retrieve information from Lightroom Classic 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 Lightroom Classic MCP:

```json
{
  "version": "1",
