How to Use the Mercado Livre Catalog MCP in Mastra AI

Q: How do I handle failed price updates in Mercado Livre Catalog using Mastra AI?

You configure a workflow step that catches errors from updateprice. If the API returns a rate limit or validation error, Mastra AI uses its built-in retry logic to attempt the update again.

Q: Can Mastra AI automatically categorize new items in the Mercado Livre Catalog?

Yes. Your agent can call getcategories via the MCP Server to find the correct path, match it with your product details, and then execute createitem with the right domain context.

Q: How does the human-in-the-loop feature work with Mercado Livre Catalog and Mastra AI?

You can set requireToolApproval on high-stakes MCP tools like deleteitem or major price changes. The workflow pauses and waits for your confirmation before changing your live marketplace listings.

Perplexity

Automate stock adjustments with Mastra AI workflows

Inventory drift will kill your seller rating if you don't handle API failures. When Mastra AI runs your sync routines, it wraps `update_stock` in a resilient workflow engine that retries automatically with exponential backoff. If the platform experiences a temporary hiccup, the agent doesn't just crash. It queues the update, retries, and only alerts your team if the sync remains broken after multiple attempts.

Validate listing attributes before publishing

Mercado Livre is notoriously strict about category attributes. Your Mastra AI agent uses `get_domain_attributes` to pull the exact schema requirements before calling `create_item` or `update_item`. This prevents wasted API calls and failed listings. The workflow engine verifies the payload against active domain rules, correcting missing fields before pushing the data live.

Deactivate stale listings via this MCP Server

Cleaning up out-of-stock items shouldn't require manual intervention. This MCP Server lets your agent scan listings with `search_items` and automatically run `delete_item` to close listings that have been empty too long. You can write custom branching logic to decide when to pause a listing versus updating its price. Your workflow evaluates the item's history before executing the deactivation.

Setup guide

Set up Mercado Livre Catalog 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 Mercado Livre Catalog 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: "mercado-livre-catalog-mcp-client",
  servers: {
    "mercado-livre-catalog-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent Mercado Livre Catalog transactions"
);
console.log(result.text);
