AI agents use schedule_recording to create or update resources in Plex — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Plex environment.
The tool creates a new scheduled recording, which is a persistent modification to the Plex server's recording queue. Although not destructive (recordings can be cancelled), it modifies server state and commits resources.
From the tool's definition Tool named 'schedule_recording' on a Plex media server; server description emphasizes read-only operations, but this tool name indicates a scheduling/modification action that creates a new recording task.
Attacks that exploit this kind of access
schedule_recording. It is categorised as a Write tool in the Plex MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Plex MCP server in PolicyLayer and add a rule for schedule_recording: 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. Nothing to install.
schedule_recording 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 schedule_recording 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 schedule_recording. 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.
schedule_recording is provided by the Plex MCP server (x10send/plex-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
