Decode Chord Functions for Claude Desktop

The `analyze_roman_numerals` tool converts a list of named chords into their Roman numeral functions, relative to any key. You hand it 'C Major,' and it spits out the scale degrees you need. It's fast. This means you don't have to manually map every chord change just to figure out if it's a ii-V-I progression or something else.

Understand Patterns with Claude Desktop

Need to know the big picture? Run `classify_progression` on a sequence of Roman numerals. This tool identifies the overarching harmonic pattern, telling you if it's building tension or resolving nicely. It takes that raw theory and turns it into actionable structure. You can see exactly where the music is going before you even write the first note.

Gauge Emotion with Claude Desktop MCP Server

The `lookup_musical_context` tool fetches metadata about a specific progression type. It hooks into style and emotional context, so you know if that chord sequence is supposed to sound 'sad' or 'epic.' It adds the human touch to the math. You get stylistic suggestions right alongside the technical analysis.

Common questions about Chord Progression Analyzer MCP in Claude Desktop

Simple. You feed it a chord list, and this MCP handles all the heavy lifting inside your local sandbox. It doesn't send anything off-site; everything stays on your machine.

Yeah, absolutely. You just need to provide the key name in the prompt, and `analyze_roman_numerals` figures out the degrees relative to that center.

It pulls style metadata. You'll learn if a given pattern is conventionally associated with something dramatic, melancholic, or otherwise high-energy.

Yup. Since it runs locally on your desktop app, all processing happens within a protected local sandbox. Nothing leaves your machine unless you tell it to.

It only handles plain strings representing named chords and Roman numeral functions, so privacy isn't a big concern here. It’s just theory stuff.
