Overview

AI-generated overview

Lets an assistant look up postal codes in over 60 countries and get matching place names, regions, and coordinates.

What you can do
The server exposes a single tool, lookup_postal_code, which takes a postal code and a country and returns the places that match, including city, state or region, latitude, and longitude. Lookups are backed by Zippopotam.us and cover more than 60 countries. It is a read-only reference lookup with no other tools.
When to use it
Useful when an assistant needs to turn a postal code into a place name or coordinates, for example to check an address, place a location on a map, or normalize location data. Not intended for bulk geocoding or address validation beyond postal code matching.
Requirements
A remote MCP endpoint at invokera.com over streamable HTTP. No authentication, API keys, environment variables, or headers are declared. Network access to the endpoint is required.
Before you install
Lookups are sent to a third-party service (Zippopotam.us) through the provider, so postal codes queried leave your environment. No credentials or write actions are declared, but confirm the provider's data handling before sending sensitive location data.

Installation

In SourceWeft

  1. Open Postal Codes in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.invokera%2Fpostal-codes/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
