## Why fl_list_installed_plugins is rated Low

This tool retrieves information about available plugins in FL Studio. The 'list' operation is non-destructive and has no side effects—it only reads and reports the current state of installed plugins. No data is created, modified, deleted, or executed. The empty description slightly reduces confidence, but the name clearly indicates a query/enumeration function typical of Read category tools.

From the tool's own definition: "Tool name 'fl_list_installed_plugins' contains the verb 'list', which is a canonical Read operation. It queries/enumerates installed VST plugins without modifying state."

## Use case

AI agents call fl_list_installed_plugins to retrieve information from FL Studio MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)
