Creates a new scene item in a scene. Args: scene_name: Name of the scene to create the item in source_name: Name of the source to add to the scene enabled: Whether to set the scene item to enabled or disabled Returns: ID of the created scene item
AI agents use create_scene_item to create or update resources in OBS MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your OBS MCP Server environment.
This tool creates a new scene item by adding a source to a scene, which is a Write operation (creates/modifies data reversibly). It is not Read (retrieves data without side effects), Execute (runs arbitrary code), Destructive (cannot be undone), or Financial.
From the tool's definition Tool name is 'create_scene_item' and description states it 'Creates a new scene item in a scene', which is a reversible creation operation that modifies OBS Studio state.
Documented attack patterns abuse exactly the kind of access create_scene_item gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OBS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create_scene_item:
{
"version": "1",
"default": "deny",
"tools": {
"create_scene_item": {
"limits": [
{
"counter": "create_scene_item_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_scene_item 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.

Creates a new scene item in a scene. Args: scene_name: Name of the scene to create the item in source_name: Name of the source to add to the scene enabled: Whether to set the scene item to enabled or disabled Returns: ID of the created scene item. It is categorised as a Write tool in the OBS MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the OBS MCP Server MCP server in PolicyLayer and add a rule for create_scene_item: 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 OBS MCP Server. Nothing to install.
create_scene_item 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 create_scene_item 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 create_scene_item. 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.
create_scene_item is provided by the OBS MCP Server MCP server (royshil/obs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
