Copy grades from one timeline item to others. Args: target_item_indices: List of 0-based indices of target items. track_type: 'video' or 'audio'. Default: 'video'. track_index: 1-based track index. Default: 1. source_item_index: 0-based source item index. Default: 0.
AI agents use ti_copy_grades 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 falls into Write rather than Execute because it performs a specific, reversible modification operation (copying grades/color corrections) rather than executing arbitrary code or triggering unpredictable external operations. While the modifications affect the video project, they can be undone (standard undo functionality).
From the tool's definition The tool 'Copy grades from one timeline item to others' modifies color grading data on multiple timeline items, which are reversible changes to project data.
Documented attack patterns abuse exactly the kind of access ti_copy_grades 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_copy_grades:
{
"version": "1",
"default": "deny",
"tools": {
"ti_copy_grades": {
"limits": [
{
"counter": "ti_copy_grades_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}ti_copy_grades 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.

Copy grades from one timeline item to others. Args: target_item_indices: List of 0-based indices of target items. track_type: 'video' or 'audio'. Default: 'video'. track_index: 1-based track index. Default: 1. source_item_index: 0-based source 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_copy_grades: 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_copy_grades 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_copy_grades 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_copy_grades. 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_copy_grades 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.
