Overview

AI-generated overview

A remote MCP server that lets an assistant look up US ZIP codes for county, time zone, Census demographics, radius searches and distances.

What you can do
Look up US ZIP codes for city, state, county and FIPS, coordinates, time zone with UTC offset, and Census demographics such as population, income, home value and rent; accepts ZIP+4, addresses and ZIPs missing a leading zero, up to 10 at a time. Find every ZIP within a radius of up to 25 miles of a ZIP or latitude/longitude point, closest first with distances. List all ZIP codes of a US city, largest population first. Reverse geocode a latitude/longitude to the nearest ZIP codes. Compute great-circle distance in miles and km between two ZIP codes.
When to use it
Useful when an assistant needs US location facts: resolving ZIP codes to counties, time zones or demographics, finding nearby ZIPs, mapping coordinates to ZIPs, or measuring distances between ZIPs.
Requirements
A remote streamable HTTP endpoint; no local runtime, package, account, API key or header is declared. Network access to the endpoint is needed.
Before you install
The service is described as free and keyless, but it is a third-party endpoint, so ZIP codes, addresses and coordinates you submit are sent to it. Coverage is limited to US ZIP codes and radius searches are capped at 25 miles.

Installation

In SourceWeft

  1. Open Ziplore: US ZIP Code API (county, time zone, demographics, radius) 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/io.github.shawmena-dotcom%2Fzip-data-api/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
