## Why ti_delete_marker_at_frame is rated Critical

This tool performs an irreversible deletion operation. While markers in video editing are metadata rather than primary content, they are project data that cannot be recovered once deleted by this tool. Deleting markers without proper authorization could disrupt editing workflows, remove important editing notes, or corrupt project organization.

From the tool's own definition: "Tool name contains 'delete' and description states 'Delete a marker at a frame on a timeline item.' The action irreversibly removes data (a marker) from a video project."

## Use case

AI agents call ti_delete_marker_at_frame to permanently remove resources in DaVinci Resolve MCP, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches DaVinci Resolve MCP:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "ti_delete_marker_at_frame"
  ]
}
