How to Use the Zippopotam.us Alternative MCP in Mastra AI

Q: Can Mastra AI handle multiple lookups using the postal code tool?

Yes. You can set up a loop in your workflow to call getlocationbypostalcode repeatedly, passing the resulting coordinates from one step into the next.

Build resilient geocoding pipelines that recover from failure with Mastra AI.

Perplexity

Conditional Geocoding Workflows

You can build complex logic. If the initial call to `get_location_by_postal_code` fails because the zip code is invalid, Mastra AI won't crash. Instead, it branches and attempts a lookup using the city/state instead. This workflow engine handles retries automatically with exponential backoff until it gets clean coordinates or gives up gracefully.

Multi-Step Postal Code Validation

Need to verify an address? Start by calling `get_postal_codes_by_city` to gather a list of potential zips. Then, in the next step of your workflow, loop through that resulting array and run `get_location_by_postal_code` on each one. Mastra AI manages this sequence, ensuring every single tool call is logged for debugging.

Failure-Proof Location Lookups

The system requires reliable data. If the first attempt to get location details fails due to a transient network error, Mastra AI automatically retries the `get_location_by_postal_code` tool call. This means your complex geocoding process succeeds even if one endpoint hiccups temporarily.

Setup guide

Set up Zippopotam.us Alternative 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 Zippopotam.us Alternative 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: "zippopotamus-alternative-mcp-client",
  servers: {
    "zippopotamus-alternative-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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

Common questions about Zippopotam.us Alternative MCP in Mastra AI

You list the MCP Server's tools in your workflow definition. You can then write conditional steps: 'If location data is missing, run `get_postal_codes_by_city` first.' This builds a robust chain.

Yes. You can set up a loop in your workflow to call `get_location_by_postal_code` repeatedly, passing the resulting coordinates from one step into the next.

It deals with structured location data: postal codes, city names, state abbreviations, and geographic coordinates. The workflow simply manages these inputs and outputs.

It automatically retries the tool call using exponential backoff. If repeated attempts fail, it notifies an admin or moves to a predefined fallback action.

The server touches public geo-spatial metadata: postal codes, city names, and coordinates. The workflow engine only passes these structured strings between steps.
