Replace a clip's underlying media while preserving subclip extents. Args: clip_id: Unique ID of the clip to replace. file_path: Absolute path to the replacement media file.
AI agents use replace_media_pool_clip_preserve_sub_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.
This tool creates or modifies data reversibly. The replacement operation changes which media file a clip references, but the operation is reversible (a user could replace it back with the original file or undo in DaVinci Resolve). It does not delete or irreversibly destroy data, nor does it execute arbitrary code or move financial resources.
From the tool's definition Tool name contains 'replace' and description states 'Replace a clip's underlying media while preserving subclip extents.' This modifies existing media pool clips by swapping their source files.
Documented attack patterns abuse exactly the kind of access replace_media_pool_clip_preserve_sub_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_media_pool_clip_preserve_sub_clip:
{
"version": "1",
"default": "deny",
"tools": {
"replace_media_pool_clip_preserve_sub_clip": {
"limits": [
{
"counter": "replace_media_pool_clip_preserve_sub_clip_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}replace_media_pool_clip_preserve_sub_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's underlying media while preserving subclip extents. Args: clip_id: Unique ID of the clip to replace. file_path: Absolute 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_media_pool_clip_preserve_sub_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_media_pool_clip_preserve_sub_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_media_pool_clip_preserve_sub_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_media_pool_clip_preserve_sub_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_media_pool_clip_preserve_sub_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.
