Perplexity

Verify Voice Leading Integrity on the MCP Server

This MCP checks if a sequence of chord voicings follows classical voice-leading rules. It analyzes the conduction between two chords, checking for forbidden parallels like parallel octaves or fifths. You'll get confirmation on whether the melodic lines maintain structural coherence based on established counterpoint theory.

Check Voice Hierarchy using Vercel AI SDK

Need to know if voices are in ascending order? Use `check_voice_hierarchy` to validate that every voice moves up or down correctly. This tool ensures the movement adheres to common practice period guidelines. It confirms the structural integrity of your piece by verifying proper note progression across adjacent chords.

Gauge Transition Quality with Vercel AI SDK

The `evaluate_smoothness` tool determines how smooth a musical transition feels. It assesses if the movement between voicings minimizes large, abrupt leaps. This gives you concrete data on perceived melodic flow, which is critical for writing believable counterpoint.

Setup guide

Set up Voice Leading Checker MCP in Vercel AI SDK

Prerequisites

Node.js 18+ and a TypeScript project
ai + @modelcontextprotocol/sdk packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies

Run npm install ai @modelcontextprotocol/sdk plus your preferred model provider (e.g. @ai-sdk/openai).
2

Create the Streamable HTTP transport

Use StreamableHTTPClientTransport with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and use tools

Call mcpClient.tools() to auto-discover all Voice Leading Checker tools. Pass them directly to generateText() or streamText() — no manual schema definitions needed.
4

Works with any model provider

Swap openai("gpt-4o") for any AI SDK provider — Anthropic, Google, Mistral. The MCP tools work identically across all supported models.

index.ts

import { experimental_createMCPClient as createMCPClient } from "ai";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";

const transport = new StreamableHTTPClientTransport(
  new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);

const mcpClient = await createMCPClient({ transport });
const tools = await mcpClient.tools();

const { text } = await generateText({
  model: openai("gpt-4o"),
  tools,
  prompt: "List recent Voice Leading Checker transactions",
});

console.log(text);
await mcpClient.close();

Common questions about Voice Leading Checker MCP in Vercel AI SDK

The MCP validates musical voice-leading integrity. It takes chord voicings as input and determines if the movement between chords follows classical harmonic rules.

It applies species counterpoint analysis, which checks for specific violations like forbidden parallels. You can confirm if your music holds up to rigorous scholarly scrutiny.

The MCP is built around standard Western classical harmony rules, specifically diatonic functional progressions. It's best for traditional counterpoint, though it acknowledges limitations when non-tonal techniques are used.

This MCP handles musical notation and chord voicing data. It processes structured inputs detailing note relationships between adjacent chords.

Yes. The tools are designed to process multiple related input points efficiently. You can analyze an entire sequence of chord transitions in one go.
