List media items in a Plex library section with inline quality details (resolution, bitrate, codec). Supports filtering by genre, year, contentRating, studio, unwatched status, resolution, and minimum bitrate.
AI agents call get_library_contents 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.
get_library_contents retrieves and filters media metadata from a Plex library without side effects. The filtering capabilities (genre, year, resolution, etc.) are all read-only queries. The blast radius of misuse is minimal — an agent could enumerate library contents excessively but cannot alter, delete, or execute anything. Severity is low because this poses no risk of data loss, code execution, or financial impact.
From the tool's definition Tool description explicitly states it 'List media items' and 'Supports filtering' — these are query/retrieval operations.
Attacks that exploit this kind of access
List media items in a Plex library section with inline quality details (resolution, bitrate, codec). Supports filtering by genre, year, contentRating, studio, unwatched status, resolution, and minimum bitrate. 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_library_contents: 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_library_contents 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_library_contents 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_library_contents. 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_library_contents 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.
