Save the current clip's grade as a still in the specified gallery album.
AI agents use save_still to create or update resources in DaVinci Resolve MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DaVinci Resolve MCP Server environment.
This tool creates new data (a still image from graded footage) and stores it in a gallery album. This is a write operation because it adds or creates new content in the project without deleting or overwriting existing data. The severity is medium because misuse could clutter galleries or consume storage, but the action is reversible (stills can be deleted).
From the tool's definition The tool "save_still" performs an action that creates or stores data: "Save the current clip's grade as a still in the specified gallery album." This creates a new still asset in the DaVinci Resolve gallery, which is a reversible write operation.
Documented attack patterns abuse exactly the kind of access save_still gives an agent:
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 save_still:
{
"version": "1",
"default": "deny",
"tools": {
"save_still": {
"limits": [
{
"counter": "save_still_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}save_still stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Save the current clip's grade as a still in the specified gallery album. It is categorised as a Write tool in the DaVinci Resolve MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the DaVinci Resolve MCP Server MCP server in PolicyLayer and add a rule for save_still: 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.
save_still is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the save_still 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 save_still. 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.
save_still 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.
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.
