AI agents call get_recently_added to retrieve information from Plex without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves/queries recently added media from Plex libraries without creating, modifying, or deleting any data. It has no side effects and poses minimal security risk even if misused by an AI agent, as it only exposes information the user already has access to on their local Plex instance.
From the tool's definition Server description explicitly states 'all read-only against your local Plex instance.' Tool name 'get_recently_added' and description 'Get recently added media items' indicate data retrieval with no modification.
Attacks that exploit this kind of access
Get recently added media items across all libraries, or scoped to a specific section. It is categorised as a Read tool in the Plex MCP Server, which means it retrieves data without modifying state.
Register the Plex MCP server in PolicyLayer and add a rule for get_recently_added: 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.
get_recently_added 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 get_recently_added 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 get_recently_added. 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.
get_recently_added 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.
