How to Use the FedEx MCP in Mastra AI

Q: Can Mastra AI automatically select the cheapest FedEx shipping option?

Yes. You can build a workflow step that calls getrates for multiple services, compares the prices, and then routes the cheapest option to createshipment.

Q: How do I set up human approval for FedEx address corrections in Mastra AI?

Use the requireToolApproval setting on your Mastra AI agent. When validateaddress flags an uncertain address, the agent pauses until a human approves the change.

Q: Can I track multiple packages in a background Mastra AI step?

Absolutely. You can run trackmultiplepackages in a scheduled workflow to monitor active shipments and trigger email alerts if any package is delayed.

Build resilient logistics workflows in Mastra AI with automatic retries and conditional branching for FedEx shipments.

Resilient FedEx Label Creation Workflows in Mastra AI

Shipping labels cannot fail silently in automated workflows. With this MCP Server, your Mastra AI agents can execute `create_shipment` inside structured workflows that automatically retry if the FedEx API drops. If the initial FedEx API call fails, the Mastra AI framework applies exponential backoff to ensure your shipping labels get generated without manual intervention. Your automated warehouse operations keep running smoothly.

Conditional Routing Based on Service Availability

Let your Mastra AI agents make smart logistics decisions on the fly. Mastra AI can use `check_service_availability` to see if overnight FedEx shipping is active for a destination zip code before booking. If Express isn't available, the Mastra AI workflow branches to check Ground rates via `get_rates` and updates your database automatically. You never promise FedEx shipping speeds you can't deliver.

Human-in-the-Loop Verification for Address Failures

When a FedEx address looks suspicious, don't just guess. Mastra AI lets you pause execution when `validate_address` returns an unresolved status, prompting a human operator to confirm. Once the operator corrects the street details, the Mastra AI workflow resumes to trigger `create_shipment` and find a nearby drop-off via `find_locations`.

Setup guide

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

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

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