Overwrite an existing layout preset with the current UI layout. Args: preset_name: Name of the preset to overwrite.
AI agents use update_layout_preset 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 persistent UI state (layout presets) but the change is reversible—the user can restore a previous preset or reconfigure it. It does not execute code, delete data irreversibly, or affect financial systems. The severity is medium because an AI agent overwriting user-customized presets could disrupt the user's workflow, but the impact is containable and recoverable.
From the tool's definition Tool overwrites an existing layout preset with the current UI layout. The term 'overwrite' indicates modification of stored configuration data. This is a reversible change to UI preferences rather than destructive deletion.
Documented attack patterns abuse exactly the kind of access update_layout_preset 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 update_layout_preset:
{
"version": "1",
"default": "deny",
"tools": {
"update_layout_preset": {
"limits": [
{
"counter": "update_layout_preset_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_layout_preset 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.

Overwrite an existing layout preset with the current UI layout. Args: preset_name: Name of the preset to overwrite. 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 update_layout_preset: 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.
update_layout_preset 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 update_layout_preset 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 update_layout_preset. 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.
update_layout_preset 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.
