create_smart_collection · Mcp Plex MCP: Risk & Policy

WHAT IT DOES

What create_smart_collection does on Mcp Plex

AI agents use create_smart_collection to create or update resources in Mcp Plex — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Plex environment.

WHY IT NEEDS A POLICY

Why create_smart_collection needs a policy

Creating a smart collection modifies the Plex library state by adding a new filterable collection. This is reversible (can be deleted via delete_collection), so it falls under Write rather than Destructive. The empty description lowers confidence slightly, but the naming convention and sibling context clearly indicate a data creation operation.

From the tool's definition Tool name 'create_smart_collection' indicates creation of a new collection object. Sibling tools include 'create_collection', 'delete_collection', 'edit_collection', confirming this server manages collections.
