Add a new Fusion composition to a timeline item. Args: item_index: 0-based item index. Default: 0.
AI agents use ti_add_fusion_comp 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 tool creates and inserts a new Fusion composition into a timeline, which is a reversible write operation that modifies project state. It does not delete data (Destructive), execute arbitrary code (Execute), or move money (Financial). While it manipulates video editing assets, the scope is limited to adding a single composition element with a default index parameter.
From the tool's definition Add a new Fusion composition to a timeline item. This creates new content within a project (Fusion composition) and modifies the timeline state by adding this composition to a timeline item.
Documented attack patterns abuse exactly the kind of access ti_add_fusion_comp 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 ti_add_fusion_comp:
{
"version": "1",
"default": "deny",
"tools": {
"ti_add_fusion_comp": {
"limits": [
{
"counter": "ti_add_fusion_comp_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}ti_add_fusion_comp 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 a new Fusion composition to a timeline item. Args: item_index: 0-based item index. Default: 0. 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 ti_add_fusion_comp: 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.
ti_add_fusion_comp 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 ti_add_fusion_comp 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 ti_add_fusion_comp. 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.
ti_add_fusion_comp 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.
