Set CDL (Color Decision List) values on a timeline item. Args: cdl: Dict with CDL values: {'NodeIndex': str, 'Slope': str, 'Offset': str, 'Power': str, 'Saturation': str}. item_index: 0-based item index. Default: 0.
AI agents use ti_set_cdl 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.
This tool modifies color grading metadata on video timeline items. While the changes are reversible (CDL values can be adjusted again), the tool creates meaningful alterations to a project's color correction state. It does not delete data (hence not Destructive), does not execute arbitrary code or shell commands (hence not Execute), and does not involve financial transactions (hence not Financial).
From the tool's definition Tool description states 'Set CDL (Color Decision List) values on a timeline item' - the verb 'Set' indicates modification of existing data (color grading parameters).
Documented attack patterns abuse exactly the kind of access ti_set_cdl gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and DaVinci Resolve MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for ti_set_cdl:
{
"version": "1",
"default": "deny",
"tools": {
"ti_set_cdl": {
"limits": [
{
"counter": "ti_set_cdl_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}ti_set_cdl 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.

Set CDL (Color Decision List) values on a timeline item. Args: cdl: Dict with CDL values: {'NodeIndex': str, 'Slope': str, 'Offset': str, 'Power': str, 'Saturation': str}. item_index: 0-based item index. Default: 0. It is categorised as a Write tool in the DaVinci Resolve MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the DaVinci Resolve MCP server in PolicyLayer and add a rule for ti_set_cdl: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches DaVinci Resolve MCP. Nothing to install.
ti_set_cdl is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the ti_set_cdl rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for ti_set_cdl. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
ti_set_cdl is provided by the DaVinci Resolve MCP server (samuelgursky/davinci-resolve-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
