Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
build_owner_query Build an owner-name search URL for one county ~192
The only tool that searches for a named owner. Fills a person or company name into that county's verified owner/taxpayer field as UPPER(field) LIKE UPPER('%NAME%'), a case-insensitive partial match, and returns a URL you can fetch or open in a browser. get_parcel_endpoint returns the endpoint and a generic sample query, not a name search, so come here for the name. This server does not execute the query and returns no parcel records: fetch the returned URL yourself. Counties that publish no owner name are refused here with that reason.
| Name | Type | Req | Description |
|---|---|---|---|
| county | string | yes | County name (e.g. 'Kane' or 'Kane County') |
| owner_name | string | yes | Owner/taxpayer name to search for (partial match, case-insensitive) |
| state | string | yes | Two-letter state abbreviation (e.g. 'IL') or full state name |
No output schema declared.
No examples provided.
find_county Resolve an uncertain county reference ~168
Use when you do NOT already know the exact state and county. Fuzzy-matches one free-text reference ('Kane', 'Cook County IL', a misspelling, or a 5-digit FIPS code) against every covered county and names each county it matched, so an ambiguous reference comes back as a list to choose from rather than a silent guess. Each match carries that county's technical record, the same record get_parcel_endpoint returns for one county. Call get_parcel_endpoint directly whenever you already hold an exact state and county; come here only to turn a vague, misspelled or coded reference into definite ones.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | County name, 'County Name State' (e.g. 'Kane IL'), or 5-digit FIPS code |
No output schema declared.
No examples provided.
get_parcel_endpoint Get one county's parcel endpoint record ~161
The default lookup once the county is known. Takes an exact state and county and returns that county's ArcGIS REST service URL, layer index, searchable field names, verified owner/taxpayer field, a generic sample ?where=…&f=json query, and the UrbanKit deep-link. If the county name is uncertain, misspelled, or you hold only a FIPS code, call find_county first. To search for a named person or company, call build_owner_query rather than editing the sample query by hand.
| Name | Type | Req | Description |
|---|---|---|---|
| county | string | yes | County name (e.g. 'Kane' or 'Kane County') |
| state | string | yes | Two-letter state abbreviation (e.g. 'IL') or full state name |
No output schema declared.
No examples provided.
list_counties List covered counties ~132
Browse what the atlas covers. Answers "is this county covered?" and "what can I search there?" with one line per county: state, name, slug, and whether owner-name search is available or the county publishes parcel numbers only. Deliberately returns NO endpoint URLs or field names; call get_parcel_endpoint for one county's technical record. Filter with a state abbreviation ('IL') or name ('Illinois'), or omit state for all ~171 counties.
| Name | Type | Req | Description |
|---|---|---|---|
| state | string | – | Optional: two-letter state abbreviation (e.g. 'IL') or full state name (e.g. 'Illinois') |
No output schema declared.
No examples provided.
