## Why set_title is rated Medium

This tool modifies photo metadata (title field) in Lightroom, which is a write operation. It is reversible (titles can be changed or deleted), not destructive, and does not execute arbitrary code or move financial resources. The severity is medium because unintended metadata changes could affect a large photo collection but are non-destructive and easily corrected.

From the tool's own definition: "Tool name 'set_title' and description 'Set Lightroom title metadata for selected photos' indicate modification of metadata fields. This is a reversible write operation that creates or modifies metadata."

## Use case

AI agents use set_title to create or update resources in Lightroom Classic MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Lightroom Classic MCP environment.
