Why set_playhead_position needs a policy

This tool triggers an external operation within DaVinci Resolve — moving the playhead to a specific frame. It does not read data, write/create persistent content, delete anything, or involve finances. It executes a state change in the running application (a UI/timeline navigation action), making Execute the most appropriate category.

From the tool's definition "Set the playhead position to a specific frame in the current timeline"

POLICY

How to control set_playhead_position

PolicyLayer is an MCP gateway — it sits between your AI agents and DaVinci Resolve MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for set_playhead_position:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "set_playhead_position": {
      "limits": [
        {
          "counter": "set_playhead_position_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

set_playhead_position stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register DaVinci Resolve MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
