Replace a clip with a new media file. Args: clip_id: Unique ID of the clip to replace. new_file_path: Absolute path to the new media file.
AI agents use replace_media_pool_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 modifies project state by replacing media references, which is reversible (the previous clip can be re-added or the project reverted). It does not permanently destroy data or execute arbitrary code. The blast radius is moderate: an AI agent could replace clips with incorrect or unwanted media, corrupting a project's creative intent, but the change can be undone.
From the tool's definition Tool name and description: 'Replace a clip with a new media file.' Accepts clip_id and new_file_path to overwrite existing media in the project.
Documented attack patterns abuse exactly the kind of access replace_media_pool_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:
{
"version": "1",
"default": "deny",
"tools": {
"replace_media_pool_clip": {
"limits": [
{
"counter": "replace_media_pool_clip_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}replace_media_pool_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 a new media file. Args: clip_id: Unique ID of the clip to replace. new_file_path: Absolute path to the new 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: 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 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 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. 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 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.
