Set the cache mode on a node. Args: node_index: 1-based node index. cache_value: -1=Auto, 0=Disabled, 1=Enabled. item_index: 0-based timeline item index. Default: 0. track_type: 'video' or 'audio'. Default: 'video'. track_index: 1-based track index. Default: 1.
AI agents use graph_set_node_cache_mode 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 state within DaVinci Resolve by changing cache settings on nodes, which affects how the application processes and renders video. It is reversible (cache mode can be changed back) and has no data deletion or financial impact. The modification is localized to rendering optimization settings rather than destructive media changes.
From the tool's definition Tool sets cache mode on a node with parameters (node_index, cache_value, item_index, track_type, track_index), modifying rendering/processing configuration of a video editing timeline.
Documented attack patterns abuse exactly the kind of access graph_set_node_cache_mode 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 graph_set_node_cache_mode:
{
"version": "1",
"default": "deny",
"tools": {
"graph_set_node_cache_mode": {
"limits": [
{
"counter": "graph_set_node_cache_mode_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}graph_set_node_cache_mode 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 the cache mode on a node. Args: node_index: 1-based node index. cache_value: -1=Auto, 0=Disabled, 1=Enabled. item_index: 0-based timeline item index. Default: 0. track_type: 'video' or 'audio'. Default: 'video'. track_index: 1-based track index. Default: 1. 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 graph_set_node_cache_mode: 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.
graph_set_node_cache_mode 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 graph_set_node_cache_mode 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 graph_set_node_cache_mode. 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.
graph_set_node_cache_mode 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.
