"Spectrum" matching MCP servers:

MCP server that enables natural language control of internet radio from Claude Code, with access to 30,000+ global stations, auto-playback via mpv, and a real-time status line with audio spectrum visualization.

An MCP server that provides a multidimensional philosophical framework for prompt engineering by mapping intent across ten distinct branches of thought. It generates a principled construction basis, including active constructs and spectrum tensions, to guide the creation of structured and intentional prompts.

Enables natural language control of test instruments like spectrum analyzers and power supplies via SCPI commands, with auto-discovery and multi-instrument session support.

Enables analysis of FTIR spectra by accepting peak lists, natural-language descriptions, or base64-encoded spectrum files and returning spectral-library candidates from the FTIR.fun API.

Enables natural language analysis of mechanical test data files (CSV, TDMS, MDF) by providing tools for channel statistics, spectrum analysis, rainflow fatigue counting, thermal state detection, and report generation.

Enables AI-assisted VST plugin tuning by connecting Claude CLI to Reaper, allowing a loop of audio capture, spectrum analysis, and live plugin parameter adjustment.
