MOST DANGEROUS TOOLS
Critical Risk

The most dangerous Opencut Controller tools

Destructive · High audio_sound_clear_saved This tool permanently deletes an entire collection of user data (all saved sounds) without the ability to undo. Destructive · Critical media_clear_all This tool permanently deletes all media assets from a video editing project without apparent undo capability or restoration mechanism. Destructive · High audio_sound_remove_saved The tool performs an irreversible deletion of a sound asset from the user's saved library. Destructive · Medium bookmark_remove The tool removes a bookmark, which is an irreversible deletion of a saved position/marker in the video editing project.

116 of Opencut Controller's 161 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Opencut Controller

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

Deny destructive operations
{
  "audio_sound_clear_saved": {
    "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
{
  "keybinding_reset_defaults": {
    "limits": [
      {
        "counter": "keybinding_reset_defaults_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
{
  "api_health_check": {
    "limits": [
      {
        "counter": "api_health_check_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 Opencut Controller — 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

Questions about Opencut Controller

Can an AI agent delete data through the Opencut Controller MCP server? +

Yes. The Opencut Controller server exposes 17 destructive tools including audio_sound_clear_saved, audio_sound_remove_saved, bookmark_remove. 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 Opencut Controller? +

The Opencut Controller server has 87 write tools including keybinding_reset_defaults, panel_reset, project_clear_export_state. 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 Opencut Controller.

How many tools does the Opencut Controller MCP server expose? +

161 tools across 4 categories: Destructive, Execute, Read, Write. 45 are read-only. 116 can modify, create, or delete data.

How do I enforce a policy on Opencut Controller? +

Register the Opencut Controller 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 Opencut Controller tool call.

Deterministic rules across all 161 Opencut Controller tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
