Destructive tools (audio_sound_clear_saved, audio_sound_remove_saved, bookmark_remove) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.

Write operations (audio_set_element_volume, audio_sound_add_to_timeline, audio_sound_save) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.

Execute tools (playback_play, playback_stop) trigger processes with side effects. Builds, notifications, workflows — all fired without throttling.

Deny destructive operations
audio_sound_clear_saved:
  rules:
    - action: deny

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

Rate limit write operations
audio_set_element_volume:
  rules:
    - rate_limit: 30/hour

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations
api_health_check:
  rules:
    - rate_limit: 60/minute

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

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

Yes. The Opencut Controller server exposes 22 destructive tools including audio_sound_clear_saved, audio_sound_remove_saved, bookmark_remove. These permanently remove resources with no undo. Intercept 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 94 write tools including audio_set_element_volume, audio_sound_add_to_timeline, audio_sound_save. Set rate limits in your policy file -- for example, rate_limit: 10/hour prevents an agent from making more than 10 modifications per hour. Intercept enforces this at the transport layer.

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

161 tools across 4 categories: Destructive, Execute, Read, Write. 43 are read-only. 118 can modify, create, or delete data.

How do I add Intercept to my Opencut Controller setup? +

One line change. Instead of running the Opencut Controller server directly, prefix it with Intercept: intercept -c io-github-jxue0-opencut-controller.yaml -- npx -y @opencut-controller. Download a pre-built policy from policylayer.com/policies/io-github-jxue0-opencut-controller and adjust the limits to match your use case.
