WHAT IT DOES

What set_label does on Lightroom Classic MCP

AI agents use set_label 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.

RISK

Why set_label is rated Medium

set_label modifies photo metadata in Lightroom Classic by assigning or removing color labels. This is a Write operation because it creates or updates data reversibly. While label changes can be undone in Lightroom, the tool directly alters catalog state.

From the tool's definition Tool description: 'Set Lightroom color label name (or empty string to clear).' This modifies metadata associated with photos by setting or clearing a label, which is reversible. The action creates or updates data (label metadata) without permanent deletion.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs set_label safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Lightroom Classic MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For set_label, this is the rule to start with:

set_label Rate-limited

set_label stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
