Perplexity

Pinpoint locations using postal code (MCP Server)

Need to know where a specific zip code hits? The `get_location_by_postal_code` tool pulls city, state, and coordinates directly. You just feed it the zip, and your agent gets back precise location data. This saves you from complex database joins when you only have a postal code field to work with.

Find all zips for a given city (MCP Server)

If the user only knows the city and state, `get_postal_codes_by_city` handles it. It spits out a list of associated postal codes. This is huge when dealing with incomplete address records. Your agent can now map an entire geographic area based on simple text input.

Handling location lookups in the OpenAI Agents SDK

The MCP Server handles two core functions: translating zip codes to coordinates, and mapping cities back to their full list of associated zips. It's a solid pair of tools for any system that deals with address validation. Your agent can use these specific `get_location_by_postal_code` and `get_postal_codes_by_city` calls to validate user input before running downstream processes.

Setup guide

Set up Zippopotam.us Alternative MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all Zippopotam.us Alternative tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Zippopotam.us Alternative tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Zippopotam.us Alternative tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="Zippopotam.us Alternative Agent",
            instructions="You have access to Zippopotam.us Alternative tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Zippopotam.us Alternative MCP in OpenAI Agents SDK

You pass the server object into the Agent constructor just like any other MCP Server. The agents auto-discover the location tools, so you don't need to write specific tool calling code for it.

The agent executes the required function call and receives clean, structured data back—like coordinates or lists of postal codes. It’s rock-solid because it runs within your defined guardrails.

Yep. The `get_location_by_postal_code` tool lets you get coordinates instantly. Plus, the agent's tracing dashboard shows exactly how many times and why it used the location data.

It provides simple, free lookup tools that plug right into your existing agent structure. You get clean output without having to manage complex external API keys or rate limits.

The server primarily touches geographic and postal code data, specifically retrieving city names, state abbreviations, zip codes, and latitude/longitude coordinates.
