List all installed packages on an Android device
AI agents call list-installed-packages to retrieve information from MCP Appium Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that enumerates installed packages. It retrieves data from the Android device without side effects, modifications, or execution of arbitrary code. While it could reveal sensitive information about installed applications, the action itself is non-destructive and reversible, fitting the Read category.

"version": "1",
"default": "deny",
"tools": {
"list-installed-packages": {}
}
