Replace a clip with another media file. Args: clip_name: Name of the clip to be replaced replacement_path: Path to the replacement media file
AI agents use replace_clip to create or update resources in DaVinci Resolve MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DaVinci Resolve MCP environment.
The replace_clip tool modifies project state by substituting one clip with another, which is a reversible write operation. While it changes project data, the original clip can be restored by replacing it back, and no data is permanently deleted. This falls under Write rather than Destructive.
From the tool's definition Tool performs 'Replace a clip with another media file' — a modification operation that changes existing media references in a project.
Documented attack patterns abuse exactly the kind of access replace_clip gives an agent:
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 replace_clip:
{
"version": "1",
"default": "deny",
"tools": {
"replace_clip": {
"limits": [
{
"counter": "replace_clip_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}replace_clip 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.

Replace a clip with another media file. Args: clip_name: Name of the clip to be replaced replacement_path: Path to the replacement media file. It is categorised as a Write tool in the DaVinci Resolve MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the DaVinci Resolve MCP server in PolicyLayer and add a rule for replace_clip: 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.
replace_clip 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 replace_clip 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 replace_clip. 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.
replace_clip 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.
