Creates a new input, adding it as a scene item to the specified scene
AI agents use obs-create-input 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 input resource in OBS Studio, which is a reversible modification. An AI agent could misuse it to spam inputs or create unwanted scene items, disrupting a live broadcast or recording setup, hence medium severity. However, since inputs and scene items can be deleted and the effect is not permanent or destructive, it falls into Write rather than Destructive.
From the tool's definition Tool name and description: 'Creates a new input, adding it as a scene item to the specified scene' — this creates a new resource (input) and adds it to a scene, which are reversible write operations.
Documented attack patterns abuse exactly the kind of access obs-create-input 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-create-input:
{
"version": "1",
"default": "deny",
"tools": {
"obs-create-input": {
"limits": [
{
"counter": "obs-create-input_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}obs-create-input 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 input, adding it as a scene item to the specified scene. 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-create-input: 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-create-input 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-create-input 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-create-input. 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-create-input 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.
