TDQS

A4.5/5.0

Scored across 6 tools

Disambiguation5/5

Each tool has a clearly distinct purpose: avm_rent and avm_value target rent vs. property value, while search_properties, search_rental_listings, and search_sale_listings each address different record types (property records, rental listings, sale listings). get_property is the only single-record retrieval tool. No overlap or ambiguity exists.

Naming Consistency5/5

All tool names follow a consistent snake_case verb_noun pattern: avm_rent/avm_value, search_properties/search_rental_listings/search_sale_listings, and get_property. The naming is predictable and uniformly formatted with action prefixes and clear resource targets.

Tool Count5/5

With 6 tools, the set is well-scoped for a real estate data server, covering property search, property detail, valuation models, and both rental and sale listings. Each tool earns its place without redundancy or excessive granularity.

Completeness5/5

The tool surface comprehensively covers the domain: property search with detailed records, single-property lookup, AVM for both rent and sale value, and listing search for both rental and sale. The read-only nature of the API means no CRUD operations are expected, and no obvious gaps remain for core workflows.

Available Tools

6 tools
avm_rentAVM long-term-rent estimate with comparablesA
Read-onlyIdempotent
Inspect

Run RentCast's automated model for long-term (12-month lease) rent and return a point rent estimate, a rentRangeLow/rentRangeHigh band, the resolved subjectProperty, and comparables[] — recent comparable rentals each scored with distance and correlation. Same subject-pinning rules as avm_value (address or latitude+longitude, plus optional subject attributes). Cached 6h upstream.

Inputs: address, daysOld, bedrooms, latitude, +7 more.

avm_valueAVM sale-value estimate with comparablesA
Read-onlyIdempotent
Inspect

Run RentCast's automated valuation model for a subject property and return a point price estimate, a priceRangeLow/priceRangeHigh band, the resolved subjectProperty, and comparables[] — recent comparable sales each scored with a distance (miles) and correlation (0-1 similarity). Pin the subject with either address or latitude+longitude; when subject attributes are unknown, supply propertyType/bedrooms/bathrooms/squareFootage (or leave lookupSubjectAttributes true to have RentCast fill them). Cached 6h upstream.

Inputs: address, daysOld, bedrooms, latitude, +7 more.

get_propertyGet one property record by idA
Read-onlyIdempotent
Inspect

Full detail for a single property record, keyed by its RentCast id (the same id returned on every search_properties, avm_value, avm_rent, and listings record). Returns 404 if no property matches the id. Cached 24h upstream.

Inputs: id (required).

search_propertiesSearch property recordsA
Read-onlyIdempotent
Inspect

Search normalized U.S. property records (owner, structural attributes, tax assessments, tax + sale history) by location. Pin a location one of three ways: a full address, a city+state(+zipCode), or a latitude+longitude point with a radius (miles). All other parameters narrow the result set. Records are cached 24h upstream, so meta.cached may be true on repeat queries.

Inputs: city, limit, state, offset, +13 more.

search_rental_listingsSearch active (or inactive) long-term rental listingsA
Read-onlyIdempotent
Inspect

Return a page of long-term (12-month lease) rental listings — same record shape as search_sale_listings (monthly price is the asking rent), but each record is tagged listingKind:"rental-long-term". Same location-pinning rules and 30-minute upstream cache as the sale-listings endpoint.

Inputs: city, limit, price, state, +15 more.

search_sale_listingsSearch active (or inactive) sale listingsA
Read-onlyIdempotent
Inspect

Return a page of for-sale listings (list price, status, days on market, MLS name/number, listing agent + office contact, and price/status history) for a location. Same location-pinning rules as search_properties (address, city+state(+zipCode), or latitude+longitude+radius). Each record is tagged listingKind:"sale". Listings move faster than records, so these are cached only 30 minutes upstream.

Inputs: city, limit, price, state, +15 more.
