Perplexity

Mastra AI shipment failure recovery

Create workflows that automatically retry failed label requests. Use `get_shipment_details` to verify shipment status before initiating a secondary action. If the carrier fails to respond, your agent handles the error gracefully. You set the logic, the agent executes the recovery steps.

Multi-step transit monitoring

Track packages through complex routes using `list_in_transit_packages`. Your Mastra AI agents monitor these states and trigger alerts if a package stalls. It handles the logic for you. If a status doesn't change for 48 hours, the agent logs it for your review.

Automated carrier rate audits

Compare your shipping costs by running `quick_delivery_health_audit` across your agent pipelines. It flags cost spikes in your account usage automatically. You save time by letting the agent identify anomalies. It only notifies you when the data hits your defined thresholds.

Setup guide

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

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

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

Common questions about EasyPost MCP in Mastra AI

Add the server URL to your client configuration and map the tools to your agent. Use the workflow engine to define your retry logic. Run `list_shipping_shipments` to verify your connection.

You can trigger any tool that creates or retrieves records. Just wrap the tool in a conditional block. Ensure you have the right permissions for your account.

The MCP integration works across all your agents. You can share shipment data between steps by passing the tool output to the next agent in your chain.

The server manages your shipment identifiers and status codes through an ephemeral connection. No data is cached locally between requests. It is a direct pipe from the API to your agent.

Check your workflow retry policies. If the tool call fails, inspect the error response from the logs. Run `get_tracking_details` manually to see if the carrier service is active.
