How to Use the Chord Progression Analyzer MCP in Vercel AI SDK

Q: Can I use Chord Progression Analyzer to check emotional intent with Vercel AI SDK?

Absolutely. You run lookupmusicalcontext to pull stylistic metadata associated with the progression type. This descriptive text can then be streamed out, giving your users a full analysis.

Visualize Harmonic Functions Live

The `analyze_roman_numerals` tool instantly converts named chords into Roman numeral functions relative to a key. Your users see the scale degrees appear in real time as your agent processes them, eliminating loading spinners. This live data streaming capability is crucial for building engaging user experiences. It lets your client show exactly how the Chord Progression Analyzer works as it analyzes chord sequences.

Classify Patterns for Immediate Feedback

Need to know if a progression is pre-chorus or bridge? The `classify_progression` tool examines a sequence of Roman numerals and identifies the overarching harmonic pattern. This works perfectly in your Vercel AI SDK setup, allowing immediate display of the classification result. You can build interactive music theory tools where users see the functional analysis results appear as they type in their code or interact with the UI.

Contextualize Results for Deep Insight

Go beyond just notes and numbers. By calling `lookup_musical_context`, your agent retrieves metadata about a progression's style and emotional intent. This adds a layer of depth that most generic models miss. You can pass this rich, descriptive context directly into your streamText function, giving the end user instant, musically informed feedback.

Setup guide

Set up Chord Progression Analyzer 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 Progression Analyzer 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 Progression Analyzer transactions",
});

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