What ti_set_property does on DaVinci Resolve MCP
AI agents use ti_set_property to create or update resources in DaVinci Resolve MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DaVinci Resolve MCP environment.
Why ti_set_property is rated Medium
The tool modifies timeline item properties, which are reversible changes to video project data. This qualifies as Write rather than Execute because it sets configuration/metadata rather than triggering external commands. Severity is high because unauthorized property modifications could corrupt editing workflows or project state, though changes are typically reversible.
From the tool's definition Tool name 'ti_set_property' (timeline item set property) combined with context of a video editing automation server suggests modifying timeline properties.
Attacks that exploit this kind of access
The rule that runs ti_set_property safely
PolicyLayer is an MCP gateway: it sits between your AI agents and DaVinci Resolve MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ti_set_property, this is the rule to start with:
ti_set_property 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 DaVinci Resolve MCP, apply this rule, and every ti_set_property call is checked against it from then on.
