Delete a library.
AI agents call delete_library to permanently remove resources in PlexMCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool performs an irreversible destructive action on structured media data. While the blast radius is limited to a single library (not the entire server), the data loss is permanent. Classified as Destructive rather than Write because deletion is not reversible.
From the tool's definition Tool name is 'delete_library' with description 'Delete a library.' The verb 'delete' combined with the scope 'library' indicates irreversible removal of data.
Attacks that exploit this kind of access
Delete a library. It is categorised as a Destructive tool in the PlexMCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Plex MCP server in PolicyLayer and add a rule for delete_library: 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 PlexMCP. Nothing to install.
delete_library 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 delete_library 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 delete_library. 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.
delete_library is provided by the Plex MCP server (sandraschi/plexmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
