AI agents use timeline_duplicate 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.
Duplicating a timeline creates new data (a copy of an existing timeline) in the DaVinci Resolve project. This is a reversible modification operation, fitting the Write category (creates or modifies data reversibly).
From the tool's definition Tool name 'timeline_duplicate' and description 'Duplicate the current timeline' indicate creation of a new copy of an existing timeline, which is a reversible write operation that modifies the project state by adding data.
Documented attack patterns abuse exactly the kind of access timeline_duplicate 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 timeline_duplicate:
{
"version": "1",
"default": "deny",
"tools": {
"timeline_duplicate": {
"limits": [
{
"counter": "timeline_duplicate_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}timeline_duplicate 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.

Duplicate the current timeline. 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 timeline_duplicate: 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.
timeline_duplicate 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 timeline_duplicate 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 timeline_duplicate. 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.
timeline_duplicate 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.
