Conditional fulfillment logic for Mastra AI

Create complex workflows that handle shipping exceptions. If `ship_order` fails due to a carrier delay, your agent uses Mastra's logic to retry or flag the item for review. This prevents manual bottlenecks. By defining a sequence, you ensure that every order reaches a shipped status without constant human intervention.

Multi-step inventory sync in Mastra AI

Orchestrate your store operations by chaining tools together. Your agent calls `get_inventory_item` to check stock before deciding whether to run `update_listing` or `delete_inventory`. It handles the logic flow automatically. You set the rules, and the agent executes the sequence, ensuring your listings always match your actual warehouse count.

Fail-safe store management in Mastra AI

Deploy your agent with confidence using built-in error handling. When `create_listing` fails, the framework catches the rejection and triggers a fallback process you define. This keeps your operations running even when API responses are unexpected. You maintain control over the process while the agent handles the execution of every task.

Setup guide

Set up eBay Seller 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 eBay Seller 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: "ebay-seller-mcp-client",
  servers: {
    "ebay-seller-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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