This MCP server delivers Australian postcode and suburb data with smart search features, enabling fast, accurate responses for customer service and AI assistants. It combines postcode-to-suburb lookups, fuzzy and phonetic search, autocomplete, radius-based geography, and sensible fallbacks to help users quickly find the right location information.

How to use

You connect to the MCP server with an MCP client and issue a range of location-focused queries. Typical tasks include finding all suburbs for a given postcode, locating postcodes for a suburb, validating suburb–postcode pairs, and listing all suburbs within a Local Government Area (LGA). You can also leverage fuzzy matching and phonetic search to handle typos or misheard names, and use geographic search to discover nearby suburbs within a radius.

Common queries you can perform include:

For example, you can use fuzzy or phonetic search to handle misspellings or misheard names, and you can request autocomplete suggestions when you start typing a suburb. If an exact match isn’t found, the system will offer smart alternatives to help you stay productive.

How to install

Prerequisites: ensure you have Python installed and a working internet connection. You will also use the FastMCP command-line tool to run the local MCP server.

Step-by-step installation and setup you can follow locally:

Clone or download the project, then install dependencies and import the data used by the server.

Install Python dependencies from the requirements file

Import postcode data into the runtime environment

Test locally with the runtime command to start a development MCP server

Run the local server in development mode using FastMCP

Alternatively, run the production server directly with Python

Notes

Deployment can be done via FastMCP Cloud or locally. FastMCP Cloud provides a streamlined workflow to publish and manage the MCP server, while local development uses the standard Python runtime and the FastMCP toolchain for testing.
