How to Use the ZIP Codes API MCP in Mastra AI

Q: How do I manage ZIP Codes API searches for cities using Mastra AI?

Use findzipsbycity within a multi-step workflow. Your agent can first get the ZIPS, then pass those results to another tool or service for further processing.

Q: Can I use Mastra AI to find ZIP Codes API by radius?

Yes, run findzipsinradius. Your workflow can be structured so that if the initial search criteria are too narrow, it automatically expands the search radius and retries.

Q: Does Mastra AI support ZIP Codes API by state lookups?

It does. You call findzipsbystate to get all codes for a given state. The framework ensures that if the connection drops, it automatically retries the query until successful.

Q: What if I need ZIP Codes API by county using Mastra AI?

Start with findzipsbycounty. This lets your agent gather the necessary ZIPS. You can then pass those results to getzipdetails in a subsequent step, guaranteeing data completeness.

Perplexity

Find ZIPS by County or State

The `find_zips_by_county` tool lets your complex workflow check for all codes within a specific county. You can build conditional branches: if the county lookup fails, then retry with a different input. This MCP Server integrates into Mastra AI's built-in engine, allowing automatic retries with exponential backoff. Your agent doesn't just run one step; it handles failure gracefully.

Calculate ZIP Code Distance

Need to know the distance between two locations? `get_zip_distance` calculates that for you. You can set up a multi-step workflow where Step 1 finds ZIPS, and Step 2 immediately uses those results to calculate distances. This is crucial for complex logistics agents. The ability of Mastra AI to manage this sequence means your workflow doesn't break when data retrieval takes multiple calls.

Get Detailed ZIP Code Data

Use `get_zip_details` to pull full demographic and geographic context for a single code. This is perfect for an agent that needs to validate location data before proceeding with a payment or record creation. Because Mastra AI handles the execution, you can wrap this call in human-in-the-loop approval steps, ensuring no critical data point slips through.

Setup guide

Set up ZIP Codes API 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 ZIP Codes API 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: "zip-codes-api-mcp-client",
  servers: {
    "zip-codes-api-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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