Create a Magic Mask on a timeline item. Args: mode: 'Forward' or 'Backward'. Default: 'Forward'. item_index: 0-based item index. Default: 0.
AI agents use ti_create_magic_mask 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 creates a new Magic Mask effect on a timeline item in DaVinci Resolve. It is a Write operation as it adds/modifies data (a mask) to the timeline item, which is reversible (the mask can be removed). It does not delete data, execute arbitrary code, or involve financial transactions. Severity is medium as misuse could alter video editing projects, but changes are reversible within the application.

Documented attack patterns abuse exactly the kind of access ti_create_magic_mask 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_create_magic_mask:
{
"version": "1",
"default": "deny",
"tools": {
"ti_create_magic_mask": {
"limits": [
{
"counter": "ti_create_magic_mask_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}ti_create_magic_mask 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.

Create a Magic Mask on a timeline item. Args: mode: 'Forward' or 'Backward'. Default: 'Forward'. 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_create_magic_mask: 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_create_magic_mask 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_create_magic_mask 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_create_magic_mask. 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_create_magic_mask 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.
