THE RISK

Low Risk

Why refresh needs a policy

The tool refreshes internal state representations to reflect current conditions. This is a synchronization/read operation that queries and updates the client-side view of Resolve's state without creating, modifying, or deleting any project data. No side effects on actual project content are indicated.

From the tool's definition Refresh all internal Resolve objects to reflect the current state.

POLICY

How to control refresh

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 refresh:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "refresh": {}
  }
}

refresh is read-only, so it stays allowed — but 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.

FAQ

Questions about refresh

What does the refresh tool do? +

Refresh all internal Resolve objects to reflect the current state. It is categorised as a Read tool in the DaVinci Resolve MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on refresh? +

Register the DaVinci Resolve MCP Server MCP server in PolicyLayer and add a rule for refresh: 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 Server. Nothing to install.

What risk level is refresh? +

refresh is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit refresh? +

Yes. Add a rate_limit block to the refresh 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 refresh completely? +

Set action: deny in the PolicyLayer policy for refresh. 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 refresh? +

refresh is provided by the DaVinci Resolve MCP Server MCP server (tooflex/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 Server tool call.

Start from DaVinci Resolve MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
