open_settings

THE RISK

High Risk

This tool triggers an external UI action within DaVinci Resolve — opening a dialog window. It doesn't purely read data (it causes a side effect in the application's UI state), nor does it write/modify data directly. It's best classified as Execute since it triggers an external operation (UI interaction) in the video editing software. Severity is low as opening a settings dialog has minimal blast radius on its own.

HOW TO CONTROL OPEN_SETTINGS

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 open_settings:

policy.json

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

open_settings 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 — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

What does the open_settings tool do? +

Open the Project Settings dialog in DaVinci Resolve. It is categorised as a Execute tool in the DaVinci Resolve MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on open_settings? +

Register the DaVinci Resolve MCP server in PolicyLayer and add a rule for open_settings: 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.

What risk level is open_settings? +

open_settings is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit open_settings? +

Yes. Add a rate_limit block to the open_settings 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.

How do I block open_settings completely? +

Set action: deny in the PolicyLayer policy for open_settings. 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.

What MCP server provides open_settings? +

open_settings 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.

Enforce policy on every DaVinci Resolve MCP tool call.
