How to Use the Chord Substitution Finder MCP in Vercel AI SDK

Q: Can I use Chord Substitution Finder with Vercel AI SDK to find swaps?

Absolutely. Just call findsubstitutions and provide the target chord. The tool will return a list of harmonically related alternatives you can drop into your composition.

Q: Is Chord Substitution Finder useful for advanced users on Vercel AI SDK?

Yeah, it’s great. You can track the tension arc with analyzeprogressiontension, which is key for writing music that feels sophisticated and intentional.

Analyze Progressions on the Fly

Need to know how tense a chord sequence is? The `analyze_progression_tension` tool calculates the harmonic tension arc of any progression. It maps out where the music builds and releases energy, giving you immediate structural feedback. This makes it easy to spot weak points in your compositions before they sound flat. Your agent uses this information to guide substitutions that maximize dramatic effect.

Find Chord Swaps Instantly

The `find_substitutions` tool finds all available harmonic chord swaps for a specific key or chord. It runs established music theory rules against your input, spitting out viable alternatives right away. This saves you from manually flipping through jazz harmony books. You just pass the chord and get a list of usable replacements to try in your piece.

Deep Dive into Chord Theory

Sometimes you need more than a name; you need the why. Use `get_substitution_detail` to pull detailed explanations on any chord substitution. This tells you exactly how that swap affects voice leading and harmonic color. It’s perfect for when you're teaching or writing notes for yourself, because it breaks down the theory behind the 'what.' You get the full picture.

Setup guide

Set up Chord Substitution Finder 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 Chord Substitution Finder 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 Chord Substitution Finder transactions",
});

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

Common questions about Chord Substitution Finder MCP in Vercel AI SDK

This MCP uses established music theory to analyze chord progressions. When you send a sequence, it doesn't guess; it calculates tension and maps substitutions based on functional harmony rules.

It processes musical notation and chord sequences (e.g., Dm7 - G7). The MCP only touches the chord structure itself, never personal user information.

Absolutely. Just call `find_substitutions` and provide the target chord. The tool will return a list of harmonically related alternatives you can drop into your composition.

Yeah, it’s great. You can track the tension arc with `analyze_progression_tension`, which is key for writing music that feels sophisticated and intentional.

The server processes musical notation, specifically chords and chord sequences. It handles text strings representing harmonic structures.
