AI agents use obs-set-output-settings 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.
The tool modifies OBS output settings, which is a reversible configuration change (Write category). It has high severity because incorrect output settings could disrupt streaming/recording quality, cause disconnects, or redirect streams/recordings to unintended destinations if paths or credentials are altered, affecting broadcast integrity and potentially reaching wide audiences.
From the tool's definition Tool name 'obs-set-output-settings' and description 'Sets the settings of an output' indicate modification of OBS output configuration (e.g., bitrate, resolution, encoder settings, file paths).
Documented attack patterns abuse exactly the kind of access obs-set-output-settings 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 obs-set-output-settings:
{
"version": "1",
"default": "deny",
"tools": {
"obs-set-output-settings": {
"limits": [
{
"counter": "obs-set-output-settings_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}obs-set-output-settings 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.
Free to start. No card required.
Sets the settings of an output. 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 obs-set-output-settings: 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.
obs-set-output-settings 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 obs-set-output-settings 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 obs-set-output-settings. 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.
obs-set-output-settings 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.
