Insert a Fusion composition into the timeline.
AI agents use timeline_insert_fusion_composition 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 and adds a new Fusion composition object to the video timeline, which is a reversible modification (compositions can be removed or replaced). It does not execute arbitrary code, delete content permanently, or move data financially. The blast radius is moderate—an agent could insert unwanted compositions that clutter a project or consume resources, but the timeline state remains recoverable.
From the tool's definition Tool name 'timeline_insert_fusion_composition' and description 'Insert a Fusion composition into the timeline' indicate creation/modification of timeline content. 'Insert' is a write operation that adds new elements to the project.

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 timeline_insert_fusion_composition:
{
"version": "1",
"default": "deny",
"tools": {
"timeline_insert_fusion_composition": {
"limits": [
{
"counter": "timeline_insert_fusion_composition_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}timeline_insert_fusion_composition 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.

Insert a Fusion composition into the timeline. 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 timeline_insert_fusion_composition: 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.
timeline_insert_fusion_composition 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 timeline_insert_fusion_composition 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 timeline_insert_fusion_composition. 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.
timeline_insert_fusion_composition 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.
