MOST DANGEROUS TOOLS

Critical Risk
Destructive · High obs-remove-input The tool performs irreversible deletion of OBS inputs (sources). Destructive · High obs-remove-profile Profile removal is a destructive action that cannot be undone through the tool itself. Destructive · High obs-remove-scene Scene removal is a destructive action that permanently deletes configuration data from OBS Studio. Destructive · High obs-remove-scene-item Removing a scene item deletes it from the scene configuration.

120 of OBS MCP Server's 200 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

HOW TO CONTROL OBS MCP SERVER

PolicyLayer is an MCP gateway — it sits between your AI agents and OBS MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Deny destructive operations
{
  "obs-remove-input": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations
{
  "obs-toggle-input-mute": {
    "limits": [
      {
        "counter": "obs-toggle-input-mute_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "get_current_preview_scene": {
    "limits": [
      {
        "counter": "get_current_preview_scene_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

  1. Create a free account and register OBS MCP Server — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Can an AI agent delete data through the OBS MCP Server MCP server? +

Yes. The OBS MCP Server server exposes 7 destructive tools including obs-remove-input, obs-remove-profile, obs-remove-scene. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through OBS MCP Server? +

The OBS MCP Server server has 56 write tools including obs-toggle-input-mute, create_scene, create_scene_item. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach OBS MCP Server.

How many tools does the OBS MCP Server MCP server expose? +

200 tools across 4 categories: Destructive, Execute, Read, Write. 80 are read-only. 120 can modify, create, or delete data.

How do I enforce a policy on OBS MCP Server? +

Register the OBS MCP Server MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every OBS MCP Server tool call.

Deterministic rules across all 200 OBS MCP Server tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
