AI agents use video_download to create or update resources in MCP Video Extraction Plus — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Video Extraction Plus environment.
This tool downloads video content from external platforms and writes it to local storage. It creates new files on the system (Write), but does not execute code, delete data, or involve financial transactions. Severity is medium because it could be misused to download large amounts of content or potentially infringing material, but the blast radius is limited.

Documented attack patterns abuse exactly the kind of access video_download gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Video Extraction Plus, and nothing reaches the server without passing your rules. This is the rule we recommend for video_download:
{
"version": "1",
"default": "deny",
"tools": {
"video_download": {
"limits": [
{
"counter": "video_download_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}video_download 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.
