AI agents use movie_import to create or update resources in Mediabox MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mediabox MCP environment.
The tool imports (ingests/creates entries for) downloaded movies into Radarr's media management database. This is a Write operation—it modifies library state by adding or organizing content. It's not Destructive since imports are reversible (content can be removed from the library).
From the tool's definition 'Import manual downloads into Radarr library' describes adding/ingesting media files into a library database, which is a reversible creation/modification operation.
Documented attack patterns abuse exactly the kind of access movie_import gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mediabox MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for movie_import:
{
"version": "1",
"default": "deny",
"tools": {
"movie_import": {
"limits": [
{
"counter": "movie_import_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}movie_import 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.

Import manual downloads into Radarr library. action=. It is categorised as a Write tool in the Mediabox MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mediabox MCP server in PolicyLayer and add a rule for movie_import: 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 Mediabox MCP. Nothing to install.
movie_import 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 movie_import 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 movie_import. 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.
movie_import is provided by the Mediabox MCP server (juancmpdev/mediabox-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mediabox MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
