First indexed and scored.

## MCP tools (4)

### `list_counties` (~93 tokens)

List covered counties

Returns all counties in the UrbanKit Atlas that have a verified ArcGIS REST parcel endpoint. Pass a state abbreviation (e.g. 'IL') or state name (e.g. 'Illinois') to filter by state. Omit state to list all ~155 counties.

Input parameters:

- `state` (string): Optional: two-letter state abbreviation (e.g. 'IL') or full state name (e.g. 'Illinois')

### `find_county` (~93 tokens)

Find a county by name or FIPS

Fuzzy-matches a county by name (e.g. 'Kane', 'Cook County', 'Cook County IL') or by 5-digit FIPS code. Returns endpoint URLs, searchable field names, owner field, sample query URL, and license info.

Input parameters:

- `query` (string, required): County name, 'County Name State' (e.g. 'Kane IL'), or 5-digit FIPS code

### `get_parcel_endpoint` (~96 tokens)

Get parcel ArcGIS REST endpoint

Returns the full ArcGIS REST service URL, layer index, searchable field names, owner field, a ready sample ?where=…&f=json query, and the UrbanKit deep-link for a specific county.

Input parameters:

- `county` (string, required): County name (e.g. 'Kane' or 'Kane County')
- `state` (string, required): Two-letter state abbreviation (e.g. 'IL') or full state name

### `build_owner_query` (~129 tokens)

Build ArcGIS owner name query URL

Constructs the exact ArcGIS REST query URL using that county's verified owner/taxpayer field. Returns a URL you can open in a browser or fetch directly. The query uses UPPER(field) LIKE UPPER('%NAME%') — case-insensitive partial match.

Input parameters:

- `county` (string, required): County name (e.g. 'Kane' or 'Kane County')
- `owner_name` (string, required): Owner/taxpayer name to search for (partial match, case-insensitive)
