How to control set_current_program_scene ↓

AI agents use set_current_program_scene 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.

Medium Risk

This tool modifies the active program scene in OBS Studio, which is a reversible configuration change (another call can switch it back). It affects what is currently being broadcast/recorded, giving it medium severity since misuse during a live stream could cause unintended scene changes visible to viewers.

Documented attack patterns abuse exactly the kind of access set_current_program_scene 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_current_program_scene:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "set_current_program_scene": {
      "limits": [
        {
          "counter": "set_current_program_scene_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

set_current_program_scene 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.

  1. Create a free account and register OBS MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
