sthan.io MCP server

This is a small helper that connects your AI assistant to sthan.io, a service that knows about US addresses. Once it is set up, you can ask your AI things like whether an address is real, what the parts of an address are, or where a place is on a map. It is handy if you work with addresses, mailings, or customer locations.

What this MCP server does

You ask your AI a question about an address or an IP address. The AI sends that question to this helper program. The helper talks to the sthan.io service, which checks real US postal records. Then the answer comes back into your chat, like whether an address is deliverable or what the coordinates are.

What you can do with it

• Check if a US address is real and deliverable
• Break a messy address into clean parts like street, city, state, and ZIP
• Suggest full addresses as you type a partial one
• Suggest US cities or ZIP codes from a few letters
• Turn an address into latitude and longitude
• Turn coordinates back into the nearest street address
• Look up the country, city, and timezone of an IP address

Try asking your AI

• “Is 123 Main St, New York, NY 10001 a real, deliverable address?”
• “Parse this address: apt 2b 500 broadway new york ny”
• “What are the coordinates of 1600 Pennsylvania Ave, Washington DC?”
• “Where is IP 8.8.8.8 located?”

What it gives back to you

You get answers right in the chat. For an address check, you get a yes or no plus a cleaned-up version with ZIP+4 and whether it is a home or a business. For geocoding, you get latitude and longitude with an accuracy note. For IP lookups, you get country, region, city, timezone, and postal code.
