Upscale a video to a higher resolution. videoUri takes in a url of a video or a data uri of a video.
AI agents use runway_upscaleVideo to create or update resources in Runway API MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Runway API MCP Server environment.
This tool processes an existing video to produce a higher-resolution version. It creates a new/modified artifact (the upscaled video) but does not irreversibly delete or overwrite data, run arbitrary code, or move money. It fits Write as it modifies/creates data reversibly via an API call. Severity is medium because it consumes API credits and processes potentially large video assets, but has limited blast radius.
From the tool's definition Upscale a video to a higher resolution. videoUri takes in a url of a video or a data uri of a video.
Documented attack patterns abuse exactly the kind of access runway_upscaleVideo gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Runway API MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for runway_upscaleVideo:
{
"version": "1",
"default": "deny",
"tools": {
"runway_upscaleVideo": {
"limits": [
{
"counter": "runway_upscalevideo_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}runway_upscaleVideo 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.

Upscale a video to a higher resolution. videoUri takes in a url of a video or a data uri of a video. It is categorised as a Write tool in the Runway API MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Runway API MCP Server MCP server in PolicyLayer and add a rule for runway_upscaleVideo: 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 Runway API MCP Server. Nothing to install.
runway_upscaleVideo 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 runway_upscaleVideo 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 runway_upscaleVideo. 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.
runway_upscaleVideo is provided by the Runway API MCP Server MCP server (runwayml/runway-api-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Runway API MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
