Set mark in/out points for a clip. Args: clip_id: Unique ID of the clip. mark_in: Mark in frame number. mark_out: Mark out frame number.
AI agents use set_clip_mark_in_out 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 clip metadata (mark in/out points) without irreversibly deleting data or executing arbitrary code. It is a write operation that can be undone by setting different mark points. While it affects video editing state, the changes are non-destructive and reversible, making it Write rather than Execute or Destructive.
From the tool's definition The tool 'set_clip_mark_in_out' modifies clip properties by setting mark in/out points, which are reversible metadata changes to a clip's editing parameters.
Documented attack patterns abuse exactly the kind of access set_clip_mark_in_out 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 set_clip_mark_in_out:
{
"version": "1",
"default": "deny",
"tools": {
"set_clip_mark_in_out": {
"limits": [
{
"counter": "set_clip_mark_in_out_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}set_clip_mark_in_out 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.

Set mark in/out points for a clip. Args: clip_id: Unique ID of the clip. mark_in: Mark in frame number. mark_out: Mark out frame number. 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 set_clip_mark_in_out: 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.
set_clip_mark_in_out 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 set_clip_mark_in_out 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 set_clip_mark_in_out. 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.
set_clip_mark_in_out 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.
