Add clip mattes from Media Storage to a MediaPoolItem. Args: media_pool_item_id: The unique ID of the MediaPoolItem. matte_paths: List of absolute file paths for the matte files.
AI agents use add_clip_mattes_to_media_pool 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 writes data by adding mattes to a media pool item, modifying the project state. It does not execute arbitrary code, delete data irreversibly, or affect finances. While it modifies a video editing project, the changes are reversible (mattes can be removed), so it is categorized as Write rather than Destructive.
From the tool's definition add_clip_mattes_to_media_pool: Add clip mattes from Media Storage to a MediaPoolItem. This tool creates or modifies media pool items by adding matte files, which are reversible changes to the project structure.
Documented attack patterns abuse exactly the kind of access add_clip_mattes_to_media_pool 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 add_clip_mattes_to_media_pool:
{
"version": "1",
"default": "deny",
"tools": {
"add_clip_mattes_to_media_pool": {
"limits": [
{
"counter": "add_clip_mattes_to_media_pool_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_clip_mattes_to_media_pool 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.

Add clip mattes from Media Storage to a MediaPoolItem. Args: media_pool_item_id: The unique ID of the MediaPoolItem. matte_paths: List of absolute file paths for the matte files. 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 add_clip_mattes_to_media_pool: 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.
add_clip_mattes_to_media_pool 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 add_clip_mattes_to_media_pool 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 add_clip_mattes_to_media_pool. 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.
add_clip_mattes_to_media_pool 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.
