Sets the scene transition override for a scene. Args: scene_name: Name of the scene transition_name: Name of the transition to use, or null to remove transition_duration: Duration in milliseconds of the transition, or null to use default
AI agents use set_scene_transition_override 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 or modifies OBS scene transition configuration settings. While it affects the streaming/recording behavior, changes are fully reversible—transitions can be reconfigured or removed without data loss or irreversible consequences. The blast radius is limited to presentation configuration in OBS.
From the tool's definition Tool modifies scene transition settings (name and duration) which are reversible configuration changes. Description uses 'sets' indicating creation/update of configuration state, and explicitly supports reversal via 'null to remove'.
Documented attack patterns abuse exactly the kind of access set_scene_transition_override 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 set_scene_transition_override:
{
"version": "1",
"default": "deny",
"tools": {
"set_scene_transition_override": {
"limits": [
{
"counter": "set_scene_transition_override_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}set_scene_transition_override 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.

Sets the scene transition override for a scene. Args: scene_name: Name of the scene transition_name: Name of the transition to use, or null to remove transition_duration: Duration in milliseconds of the transition, or null to use default. 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 set_scene_transition_override: 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.
set_scene_transition_override 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_scene_transition_override 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_scene_transition_override. 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_scene_transition_override 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.
