What add_keywords does on Lightroom Classic MCP
AI agents use add_keywords 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.
Why add_keywords is rated Medium
This tool creates or modifies keyword metadata on photos in a reversible manner. It does not execute code, delete data, move money, or trigger external operations—it simply adds organizational metadata. This is a classic Write operation.
From the tool's definition Tool name 'add_keywords' and description 'Add keywords' indicates creation/modification of metadata. The hierarchical format support (A > B > C) confirms it structures and persists keyword data in the Lightroom catalog.
Attacks that exploit this kind of access
The rule that runs add_keywords 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 add_keywords, this is the rule to start with:
add_keywords 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Lightroom Classic MCP, apply this rule, and every add_keywords call is checked against it from then on.
