How to Use the Mercado Libre MCP in Mastra AI

Q: Can Mastra AI automatically adjust pricing based on Mercado Libre promotion eligibility?

Yes. Your workflow can run getpromotioncandidate on a schedule, check the parameters, and then use Mastra's conditional branching to update prices when items qualify for discounts.

Q: How does the Mastra AI retry engine handle Mercado Libre API timeouts on this MCP Server?

If getshipment or getorder fails due to platform rate limits, Mastra's built-in backoff engine automatically retries the call. This prevents your automated shipping pipelines from breaking during high-traffic events.

Q: Can I test my workflows without affecting my real store?

Yes. You can use createtestuser to spin up a sandbox buyer and seller account, allowing you to safely run end-to-end transaction tests.

Q: How is my Mercado Libre buyer message data secured in this MCP Server?

Your message logs fetched via getpostsalemessages are processed entirely in memory within zero-trust V8 isolates. Vinkius never persists your buyer conversations, keeping your private business communications private.

Build automated Mercado Libre workflows using Mastra AI to handle inventory, shipping delays, and buyer claims without manual intervention.

Handle Claims Automatically via Mastra AI

`get_claim` is the starting point for Mastra AI agents to analyze buyer disputes and trigger conditional resolution paths. If a buyer opens a dispute, the workflow engine automatically pulls the claim details and decides whether to issue a refund or ask for more info. To get the full picture, `get_return_details` fetches the carrier tracking status of the returned item. Mastra's retry logic ensures that if the API is temporarily rate-limited, the agent backs off and retries until the return status is confirmed.

Automate Product Listings with this MCP Server

`predict_category` lets your Mastra agent determine the most accurate category ID for a new product based solely on its title. The workflow engine can branch based on the confidence score, routing low-confidence predictions to a human-in-the-loop approval step before publishing. When the category is locked in, `create_item` publishes the listing details, pricing, and images directly to the marketplace. This automated pipeline ensures your catalog stays synchronized across all platforms without manual data entry.

Trigger Post-Sale Workflows on Order Confirmation

`get_post_sale_messages` scans your active orders to detect new buyer inquiries inside the transaction chat. Mastra workflows can schedule regular checks, ensuring that no buyer message goes unanswered for more than a few minutes. If a message requires a standard logistical update, `send_post_sale_message` fires off the response with tracking details. This keeps your response times low and protects your seller reputation score from dipping.

Setup guide

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

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

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