WHAT IT DOES

What fl_list_midi_ports does on FL Studio MCP Server

AI agents call fl_list_midi_ports 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.

RISK

Why fl_list_midi_ports is rated Low

This tool queries and returns information about MIDI ports available to FL Studio without creating, modifying, deleting, or executing operations on them. It is purely informational. The empty description lowers confidence slightly, but the naming convention strongly indicates a read-only operation. Severity is low because listing ports poses minimal risk even if misused—it only reveals system configuration details.

From the tool's definition Tool name 'fl_list_midi_ports' indicates enumeration/listing of available MIDI ports. The 'list' verb and lack of modification operations suggest data retrieval with no side effects.
