# Roman Numeral Converter MCP for AI Agents AI Agent Connect

> Roman Numeral Converter turns musical chord names into Roman numerals and handles automatic transposition. It bridges the gap between raw notes and functional harmony, making it easy to analyze progressions or move them to different keys without losing their underlying structure.

## Description

The Roman Numeral Converter MCP lets you bridge the gap between note-based progressions and functional harmonic notation. When you're working on a piece of music, moving from 'what notes are played' to 'what is the harmonic function' can feel like a chore. You might have a solid progression in C major, but you need to see it in Roman numerals to understand the underlying movement. This Connector handles that heavy lifting for you. Instead of manually calculating scale degrees or getting tripped up by complex modulations, you just feed the chord sequence into your agent. It identifies the underlying functions and gives you the notation you need for theory analysis or songwriting. If you're looking to move that progression to a different key, it doesn't just shift the notes. It keeps the harmonic relationship intact, so a I-vi-IV-V in C stays a I-vi-IV-V in G. It's a huge time saver for anyone who spends a lot of time in the weeds of music theory or complex arrangement. You can find this tool in the Vinkius catalog to get your agent set up with these capabilities. It makes the transition between different keys and functional analysis feel instantaneous, allowing you to focus on the creative side of composition rather than the math of music theory.

## Prompt Examples

**Prompt:** 
```
What is the Roman numeral for a D minor chord in the key of C major?
```

**Response:** 
```
In the key of C major, a D minor chord functions as the ii degree. In Roman numeral notation, this is written as **ii**.
```

**Prompt:** 
```
Can you transpose C-Am-F-G to the key of G major?
```

**Response:** 
```
Here is your transposed progression in G major: 

* **G**
* **Em**
* **C**
* **D**

This maintains the same I-vi-IV-V harmonic structure.
```

**Prompt:** 
```
Analyze this progression for me: F-Bb-C-Gm.
```

**Response:** 
```
Here is the analysis for your progression:

| Chord | Roman Numeral |
|---|---|
| F | **I** |
| Bb | **IV** |
| C | **V** |
| Gm | **i** |
```

## Capabilities

### Convert chord strings to Roman numerals
Turn a list of chord names into functional notation for theory analysis.

### Identify the harmonic function of a chord
Find out what a chord does in a specific key, such as a vi or a IV.

### Transpose progressions while keeping numerals
Shift a chord sequence to a new key without changing its underlying harmonic structure.

### Extract chord metadata
Pull specific musical details about a chord for deeper analysis.

### Parse raw chord strings into data
Convert messy text inputs into structured data your agent can use.

## Use Cases

### Music theory homework
A student pastes a long list of chords and asks their agent to provide the Roman numeral analysis for a music theory exam.

### Key shifting for vocals
A producer has a great progression in D major but needs it in Bb major for the vocalist; they ask the agent to transpose it.

### Rapid key prototyping
A songwriter wants to see how a I-IV-V-I progression sounds in five different keys in one minute.

### Pop song analysis
A musician uploads a list of chords from a pop hit and asks the agent to identify the primary harmonic functions.

## Benefits

- Stop manually calculating scale degrees by using `resolve_harmonic_function` to get instant Roman numeral results.
- Move your songs to any key instantly without breaking the harmony by using `transpose_progression`.
- Get a clear view of your song's structure by using `parse_progression_string` to turn raw text into theory data.
- Understand chord properties deeper by using `get_chord_metadata` to pull specific musical details.
- Save hours of theory work by having your agent handle the conversion between note names and functional notation.

## How It Works

The bottom line is it turns messy chord lists into clean, functional music theory data.

1. Input a sequence of chords or a specific musical key.
2. The agent processes the notes and identifies their scale degrees.
3. You get back a clean list of Roman numerals or a transposed chord sequence.

## Frequently Asked Questions

**What is the Roman Numeral Converter MCP used for?**
It helps musicians and students convert standard chord names into Roman numerals. It's great for analyzing the underlying harmony of a song or moving a progression to a different key.

**Can I use Roman Numeral Converter to change keys?**
Yes. You can give your agent a progression and a target key, and it will shift the notes while keeping the harmonic function the same.

**Is Roman Numeral Converter good for music theory students?**
It's a huge time saver for students. It automates the process of identifying scale degrees, letting you focus on understanding the theory rather than doing the manual math.

**How does Roman Numeral Converter handle different keys?**
You can specify any key, and the Connector will figure out the correct Roman numerals for the chords you provide. It ensures your harmonic structure stays consistent across different keys.

**Can Roman Numeral Converter analyze a long list of chords?**
Yes, it can parse a string of chords and break them down into their functional parts. This makes it easy to see the 'story' of a complex musical piece.

**What can this tool do?**
It parses chord progressions, identifies harmonic functions, and transposes sequences using `parse_progression_string` and `transpose_progression`. Tools available: `your_tool_name`.

**How do I use the transposition feature?**
Use `transpose_progression` by providing your original progression, the source key, and the target key.

**Does it support chord extensions?**
Yes, you can use `get_chord_metadata` to retrieve detailed information including extensions like 7, 9, or 11.
