Automate music profile audits with Mastra AI agents

The `get_user_info` tool retrieves core profile metrics to initiate automated audit workflows in your Mastra agent. You set up conditional loops that trigger when a user's play count hits specific milestones. Mastra handles the complex branching logic if a profile returns empty or rate-limited. The agent automatically retries the query or alerts your system based on your custom workflow rules.

Build self-healing music curation pipelines

The `get_loved_tracks` and `get_top_tags` tools allow your agent to build and refine custom tag-based playlists. Your workflow scans a user's loved list, categorizes them by current tag trends, and flags anomalies. If the connection drops mid-run, Mastra's built-in exponential backoff ensures the pipeline resumes without losing state. You don't have to write manual retry logic for unstable external connections.

Sync listening histories via MCP Server workflows

The `get_recent_tracks` tool pulls fresh scrobbles to keep external databases in sync with active listening habits. Our Mastra agent runs this on a schedule, mapping track metadata directly to your internal schema via the MCP Server. You configure human-in-the-loop approvals before major database writes occur. The system pauses, sends a Slack ping, and waits for a green light before committing new entries.

Setup guide

Set up Last.fm MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All Last.fm tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "lastfm-mcp-client",
  servers: {
    "lastfm-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "Last.fm Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to Last.fm tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent Last.fm transactions"
);
console.log(result.text);

Common questions about Last.fm MCP in Mastra AI

You use Mastra AI's built-in workflow engine to configure automatic retries. If the server hits a rate limit, the system backs off exponentially before trying again.

Yes, you can chain get_loved_tracks with get_artist_info in a single workflow. Mastra passes the output of one tool directly to the next without manual glue code.

You initialize the client with the server's SSE URL and pass the tools directly to your agent configuration. Mastra automatically registers the schemas and makes them available to your LLM.

No, the client automatically detects whether the server is using Streamable HTTP or SSE. It configures the connection behind the scenes so you can focus on writing agent logic.

Absolutely. Your scrobble history and profile metrics are processed in memory through ephemeral Vinkius MCP sandboxes. We never write your private music listening logs to permanent storage.
