Connect Claude & ChatGPT to Smarty
Ask your AI whether a US address is real, what its correct USPS form is, or to clean up a list of customer addresses with Smarty. It validates and standardizes addresses one at a time or several in one call, and returns the matching candidates with ZIP+4, county and coordinates. This connection covers Smarty's US Street Address API.
Free plan, no credit card. Takes about a minute.
Try asking
“Is 350 5th Ave, New York, NY 10118 a valid address?”
The AI verifies the address and returns the USPS-standardized match. If no candidate comes back, Smarty found no match.
“What is the ZIP+4 for this shipping address?”
It standardizes the address and reads the ZIP+4 code from the matching candidate.
“Which county is this customer's address in?”
It verifies the address and returns the county along with the standardized address.
What your AI can do
Validate addresses
Check whether a US street address matches a real address and get the USPS-standardized candidates.
ZIP+4, county and coordinates
Each match comes with ZIP+4, county and coordinates, useful for shipping, mapping and reporting.
Batch checks
Validate several addresses in one call and match the results back to your list with input IDs.
“Get the coordinates for our three warehouse addresses.”
It validates all three in one batch call and returns the latitude and longitude of each match.
“Clean up these 20 customer addresses before we ship.”
It sends them as a batch with an input ID for each, then shows the standardized versions and flags any without a match.
“The customer wrote '100 main street apt 4 springfield il'. Fix it.”
It passes the address as one line and returns the standardized street, city, state and ZIP+4.

Questions
What can the AI do in Smarty?
It can validate, standardize and geocode US street addresses, one at a time or several in one call. For each address it gets the matching USPS-standardized candidates with ZIP+4, county and coordinates.
Does the AI see my Smarty credentials?
No. Your Smarty Auth ID and Auth Token are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.
Can I control what the AI is allowed to do?
Yes. You choose which tools are switched on, for example single lookups without batch checks. Both Smarty tools look up addresses and do not change anything in your Smarty account. Every tool call is logged, so you can see which addresses were checked.
Does it work with ChatGPT?
Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.
What does it cost?
PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Smarty account.
Does it work for addresses outside the US?
No. This connection uses Smarty's US Street Address API, so it validates and standardizes US street addresses only.
