Get the custom data of a timeline marker. Args: frame_id: Frame number of the marker.
AI agents call timeline_get_marker_custom_data 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 tool queries and retrieves marker metadata from a timeline without altering, executing, or deleting anything. It is a pure read operation on DaVinci Resolve project data. The blast radius of misuse is minimal — an AI agent could retrieve marker information, but cannot cause irreversible damage, financial loss, or unintended external effects. Severity is low because viewing metadata poses no significant risk.
From the tool's definition Tool name 'timeline_get_marker_custom_data' and description explicitly state 'Get the custom data' — a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access timeline_get_marker_custom_data 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_get_marker_custom_data:
{
"version": "1",
"default": "deny",
"tools": {
"timeline_get_marker_custom_data": {}
}
}timeline_get_marker_custom_data is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the custom data of a timeline marker. Args: frame_id: Frame number of the marker. 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 timeline_get_marker_custom_data: 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_get_marker_custom_data 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 timeline_get_marker_custom_data 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_get_marker_custom_data. 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_get_marker_custom_data 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.
