Get number of nodes in the color graph for a timeline item. Args: item_index: 0-based item index. Default: 0. track_type: 'video' or 'audio'. Default: 'video'. track_index: 1-based track index. Default: 1.
AI agents call graph_get_num_nodes to retrieve information from DaVinci Resolve MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only query operation that retrieves information about the color graph structure in DaVinci Resolve. It takes parameters to specify which timeline item and track to inspect, then returns a numeric count. No data is created, modified, deleted, or executed. The blast radius of misuse is minimal—an AI agent cannot cause harm by repeatedly calling this function.
From the tool's definition Tool name 'graph_get_num_nodes' and description 'Get number of nodes in the color graph' indicate a retrieval operation with no side effects. The function only queries and returns the count of nodes without modifying any state.
Documented attack patterns abuse exactly the kind of access graph_get_num_nodes 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_get_num_nodes:
{
"version": "1",
"default": "deny",
"tools": {
"graph_get_num_nodes": {}
}
}graph_get_num_nodes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get number of nodes in the color graph for a timeline item. Args: item_index: 0-based item index. Default: 0. track_type: 'video' or 'audio'. Default: 'video'. track_index: 1-based track index. Default: 1. It is categorised as a Read tool in the DaVinci Resolve MCP MCP Server, which means it retrieves data without modifying state.
Register the DaVinci Resolve MCP server in PolicyLayer and add a rule for graph_get_num_nodes: 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_get_num_nodes is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the graph_get_num_nodes 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_get_num_nodes. 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_get_num_nodes 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.
