AI agents call radarr_get_missing to retrieve information from Plex MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though radarr_get_missing only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Documented attack patterns abuse exactly the kind of access radarr_get_missing gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Plex MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for radarr_get_missing:
{
"version": "1",
"default": "deny",
"tools": {
"radarr_get_missing": {}
}
}radarr_get_missing is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Plex MCP Server MCP server in PolicyLayer and add a rule for radarr_get_missing: 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 Plex MCP Server. Nothing to install.
radarr_get_missing is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the radarr_get_missing 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 radarr_get_missing. 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.
radarr_get_missing is provided by the Plex MCP Server MCP server (niavasha/plex-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
