AI agents call roku_apps to retrieve information from Roku MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about installed apps without side effects or state changes. It is a pure query operation that fits the Read category. Severity is low because listing installed apps presents minimal risk—it only exposes metadata about what applications exist on the device, which is non-sensitive enumeration data. No code execution, data modification, or destructive actions are possible.
From the tool's definition Tool 'roku_apps' uses GET request to query and list installed applications. Description states 'List all installed apps' with no modification, deletion, or execution of commands. Returns only informational data: id, name, version, type.
