Get current treble gain level
AI agents call getTreble to retrieve information from Lyngdorf MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only reads the current treble gain setting from a Lyngdorf Audio device. It performs no writes, deletions, code execution, or financial operations. The absence of any modifying verbs (set, adjust, change) and the use of 'Get' confirms it is a read-only operation with minimal security risk. Consistent with sibling tools like getAudioStatus, getBalance, getBass which are clearly informational queries.
From the tool's definition Tool name 'getTreble' with description 'Get current treble gain level' indicates a query operation that retrieves audio parameter data without modification.
