Gets the blend mode of a scene item. Args: scene_name: Name of the scene the item is in scene_item_id: ID of the scene item Returns: Current blend mode of the scene item
AI agents call get_scene_item_blend_mode to retrieve information from OBS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the current blend mode property of a scene item in OBS Studio. It performs a read-only retrieval operation that does not modify, delete, or execute any actions. The parameters are simple identifiers (scene_name, scene_item_id) used to locate the item being queried. The return is informational only, with no capability to alter system state or trigger external operations.
From the tool's definition Tool name 'get_scene_item_blend_mode' and description 'Gets the blend mode of a scene item' with return value 'Current blend mode of the scene item' indicate a retrieval operation with no side effects.

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 get_scene_item_blend_mode:
{
"version": "1",
"default": "deny",
"tools": {
"get_scene_item_blend_mode": {}
}
}get_scene_item_blend_mode is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
