AI agents use upload_video to create or update resources in PixVerse MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your PixVerse MCP environment.
The tool appears to create or modify data by accepting a video file and storing it in the PixVerse system. This is a Write-category operation (reversible data creation). Severity is medium because while uploads are generally safe, they could consume server resources, trigger processing pipelines, or introduce unwanted content if misused by an agent.
From the tool's definition Tool name 'upload_video' indicates a file upload operation that creates or stores video content on the server. The description is empty, limiting certainty.
Documented attack patterns abuse exactly the kind of access upload_video gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and PixVerse MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for upload_video:
{
"version": "1",
"default": "deny",
"tools": {
"upload_video": {
"limits": [
{
"counter": "upload_video_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}upload_video 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.

upload_video. It is categorised as a Write tool in the PixVerse MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the PixVerse MCP server in PolicyLayer and add a rule for upload_video: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches PixVerse MCP. Nothing to install.
upload_video is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the upload_video rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for upload_video. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
upload_video is provided by the PixVerse MCP server (pixverseai/pixverse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
