What it does

Give US street addresses, or a state with parcel IDs, owner names, or ZIP codes. The actor reads six public statewide parcel layers built from county assessor rolls (NC, NY in 38 counties, FL, CO, AR, WI) and returns one row per parcel with the owner of record, the mailing address on the roll, the property address, assessed and market values, land use, and last sale where the county publishes it. It returns no phone numbers or emails and uses no data broker.

All of the work runs on Apify. This package is a thin client that starts the actor run, waits for it, and hands back the dataset rows.

Quick start

You need Node.js 18 or newer and an Apify account with an API token.

Add this to your Claude Desktop config (claude_desktop_config.json), Cursor, or any MCP client:

{
  "mcpServers": {
    "mamba-property-owner-records": {
      "command": "npx",
      "args": [
        "-y",
        "@mambalabsdev/mcp-property-owner-records"
      ],
      "env": {
        "APIFY_TOKEN": "your-apify-token"
      }
    }
  }
}

Restart the client. The lookup_property_owner_records tool appears.

Prerequisites

Node.js 18 or newer.
An Apify API token from console.apify.com/account/integrations, set as APIFY_TOKEN. The server lists its tool without a token; a call needs one.

Example prompts

"Who owns 222 W Hargett St, Raleigh, NC 27601?"
"List the parcels the City of Raleigh owns in Wake County, North Carolina."
"Export the owners of record for every parcel in ZIP 27601."

Tool

lookup_property_owner_records. One tool. Example arguments:

{
  "addresses": [
    "1 E Edenton St, Raleigh, NC 27601"
  ],
  "owner_names": [
    "CITY OF RALEIGH"
  ],
  "state": "NC",
  "county": "Wake",
  "max_results_per_lookup": 5
}

Inputs

Every buyer facing input of the actor. Omitted inputs take the actor's own defaults.

Input	Type	Required	Description
`addresses`	array	no	Full US street addresses with city and state, one per entry, such as 1 E Edenton St, Raleigh, NC 27601. The US Census geocoder places each one and the actor returns the parcel at that point. The state comes from the address, so the state field is not needed. An address it cannot place, or one outside the covered states, is a free row.
`parcel_ids`	array	no	Parcel numbers as the county writes them. Needs state. Add county, because the same number can repeat in two counties.
`owner_names`	array	no	Owner names as the roll writes them, usually last name first for a person (SMITH JOHN) and the full name for a company (CITY OF RALEIGH). Needs state. Matches names that start with the text unless owner_match is contains.
`zip_codes`	array	no	5 digit property ZIP codes. Returns every parcel in the ZIP up to max_results_per_lookup. Needs state.
`state`	string	no	Two letter state for parcel_ids, owner_names, and zip_codes: NC, NY, FL, CO, AR, or WI.
`county`	string	no	Optional county name, such as Wake or St. Lawrence, to narrow parcel_ids, owner_names, and zip_codes. Does not apply to addresses.
`owner_match`	string	no	starts_with (default): the owner name starts with your text. contains: the text appears anywhere in the name; slower, so add a county.
`max_results_per_lookup`	number	no	Parcel rows per address, parcel ID, owner name, or ZIP, from 1 to 5000. Default 25.
`max_charge_usd`	string	no	Optional. The run stops before a charge that would pass this amount. Summary rows are always returned.
