AI agents call series_remove to permanently remove resources in Mediabox MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing a series from Sonarr permanently deletes the series entry and associated metadata from the media library. This action cannot be undone and represents permanent data loss. While the underlying media files may or may not be physically deleted depending on Sonarr configuration, the library removal itself is irreversible.
From the tool's definition Tool name 'series_remove' combined with description 'Remove a series from Sonarr' indicates permanent deletion of media library content. The verb 'remove' in the context of media server management denotes irreversible deletion.
Documented attack patterns abuse exactly the kind of access series_remove 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 series_remove:
{
"version": "1",
"default": "deny",
"hide": [
"series_remove"
]
}series_remove disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Remove a series from Sonarr. It is categorised as a Destructive tool in the Mediabox MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mediabox MCP server in PolicyLayer and add a rule for series_remove: 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.
series_remove is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the series_remove 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 series_remove. 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.
series_remove 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.
