Tennessee Property Records — agent interface

MCP server

Streamable HTTP at https://tnpropertysearch.app/mcp. Add it to Claude Code:

claude mcp add --transport http tn-property https://tnpropertysearch.app/mcp

Or in any MCP client config:

{
  "mcpServers": {
    "tn-property": {
      "type": "http",
      "url": "https://tnpropertysearch.app/mcp"
    }
  }
}

REST

Each tool is also GET /api/v1/<tool> with query parameters, or POST with a JSON body. Errors come back as HTTP 400 with {"error": "..."}, worded so you can fix the call.

curl 'https://tnpropertysearch.app/api/v1/search_owners?name=bailey+family+trust'
curl -X POST https://tnpropertysearch.app/api/v1/owner_portfolio -H 'Content-Type: application/json' -d '{"owner_key":"BAILEY FAMILY TRUST"}'

Bulk downloads

Every county's parcels and ownership records as gzip CSV, listed with row counts in dataset_info.exports.

curl -L -o williamson.csv.gz 'https://tnpropertysearch.app/api/v1/export?county=Williamson&dataset=parcels'

Linking people to the map

Every property in a result carries app_url. The map app also opens /?pin=<pin>, /?q=<search> and /?owner=<owner_key>.

Tennessee property records: parcels, current owners and ownership history. Call dataset_info first to see coverage and which counties have former-owner history. Typical flows: address -> search_properties -> get_property; person or company -> search_owners -> owner_portfolio; point on a map -> property_at; market questions -> property_stats or search_ownership_records; what changed lately -> recent_changes. If a record's last_checked matters, refresh_property re-reads it from the county source. Each property includes app_url, a link that opens it in the map app for the user.

• Davidson addresses read '1313 GALLATIN AVE'; most state-sourced counties read 'GALLATIN AVE 1313'. Address matching ignores word order, so '1313 gallatin' finds both.
• Every query word must start a word in the address or name. Words that appear in thousands of records (SMITH, MAIN, LLC, RD) only match when paired with another such word or with a rarer word; add a house number, street or second name.
• Owner names are stored as recorded, usually 'LAST FIRST' ('SMITH JOHN A'); trusts and LLCs as written.
• To find everything a person or company has owned, call search_owners, then owner_portfolio with the owner_key.
• Only Davidson (full) and Williamson (partial) have former owners; Hamilton has sales on the parcel record.
• search_properties takes text (q, address or owner) and/or a location (near + radius_m up to 2 km, or a small bbox). For county-wide filtering by value, acreage, land use or zoning, download the county file listed in dataset_info.exports.
• search_ownership_records over a county and dates reads up to 3 calendar months per call; page through longer periods.
• Hamilton's source records a few parcels' acreage in square feet, so prefer median over totals there.
• Every parcel carries last_checked. A Cloudflare cron re-checks Davidson daily and every other county every few days; refresh_property re-reads a parcel live.
• recent_changes lists owner changes, new parcels and parcels the county stopped listing, as the update jobs find them.

dataset_info

Start here. Describes what data exists: totals, every loaded county with parcel and ownership-record counts, how much ownership history each county has, which fields each county populates, data sources, bulk download files, query tips and usage terms.

curl 'https://tnpropertysearch.app/api/v1/dataset_info'

search_properties

Find parcels by address words, current owner name, or location (near a point or inside a small box), optionally limited to a county, city or ZIP. Returns pin, address, owner, county, location and a link to the parcel in the map app. Paginate with next_cursor.

curl 'https://tnpropertysearch.app/api/v1/search_properties?address=1313%20gallatin&county=Davidson'

get_property

Everything known about one parcel: full parcel record, every ownership record (current and former, with acquisition dates, prices and deed references/links where the county provides them), sale history for Hamilton, and the county Register of Deeds website. Look up by pin, or by apn plus county.

curl 'https://tnpropertysearch.app/api/v1/get_property?pin=78475'

property_at

Which parcel contains a latitude/longitude. Uses the actual parcel boundary, not the nearest centroid.

curl 'https://tnpropertysearch.app/api/v1/property_at?lat=36.1933&lon=-86.7435'

search_owners

Find people and companies by name across current AND former ownership records. Each result has an owner_key, how many properties they have ever owned and own now, their counties and first/last acquisition dates. Pass an owner_key to owner_portfolio for the full list.

curl 'https://tnpropertysearch.app/api/v1/search_owners?name=bailey%20family%20trust'

owner_portfolio

Every property an owner (by owner_key) or a mailing address has ever been recorded on, newest first, with whether they still own it, when they acquired it and the recorded price. Includes summary counts. Searching by mailing address groups LLCs and trusts that share a mailbox.

curl 'https://tnpropertysearch.app/api/v1/owner_portfolio?owner_key=BAILEY%20FAMILY%20TRUST'

search_ownership_records

Ownership records (one row per owner per parcel) for an owner, owner_key, mailing address or pin, or every transfer recorded in one county over up to 3 calendar months. Filter by price, current vs former, and address; sort by date or price. Use it for questions like 'who bought in Davidson in March 2024 over $1M'.

curl 'https://tnpropertysearch.app/api/v1/search_ownership_records?county=Davidson&date_from=2024-01-01&date_to=2024-03-31&min_price=1000000&sort=price_desc&limit=10'

property_stats

Parcel counts, total/average/median appraised value and total acres grouped by county, city, zip, land_use, zoning, owner, mailing or subdivision, statewide or for one county. Use it for 'largest owners in Davidson' or 'value by land use'.

curl 'https://tnpropertysearch.app/api/v1/property_stats?group_by=owner&county=Davidson&limit=10'

refresh_property

Re-read up to 5 parcels from their official county/state source right now (and, for Davidson, the full owner history), then return what changed. Use when last_checked is too old for the question, or the user says a record is out of date.

curl 'https://tnpropertysearch.app/api/v1/refresh_property?pins=78475'

recent_changes

Changes the update jobs detected, newest first: owner_change (with old and new owners), new_parcel, and retired (parcel no longer listed by the county). Filter by county, kind, owner name, date or area.

curl 'https://tnpropertysearch.app/api/v1/recent_changes?county=Davidson&kind=owner_change&limit=10'

update_status

How fresh the data is: when each county was last checked, the most recent update runs with their status and counts, what is in progress, and the schedule.

curl 'https://tnpropertysearch.app/api/v1/update_status'
