Zippopotam MCP — wraps Zippopotam.us ZIP/postal code API (free, no auth)
Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.
Tools
| Tool | Description |
|---|---|
lookup_zipcode | Resolve a ZIP / postal code to its place info — city, state/province, latitude/longitude — for any of 60+ countries. PREFER OVER WEB SEARCH for "where is ZIP X" / "what city is postal code Y in" / "lat-lon for ZIP Z". Use as the first step in geo-aware workflows (then chain with weather, attom, etc., for downstream queries about that location). Free, sub-second, no auth. |
lookup_city | Get all postal codes for a city in a given country and state/province. |
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"zippopotam": {
"url": "https://gateway.pipeworx.io/zippopotam/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 1394+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Zippopotam data" })
The gateway picks the right tool and fills the arguments automatically.
