Search homes.com listings

homes_search_properties
Read-onlyIdempotent

Search homes.com listings by location with filters for property type, listing type, and price. Returns address, price, beds, baths, and listing details.

Instructions

Search homes.com listings by free-text location (city, ZIP, neighborhood). Optionally filter by property_type (single_family/condo/townhouse/land/mobile/multi_family), listing_type (for_sale/sold/for_rent/open_houses/new_construction), and sort (newest). Slugifies the location into homes.com's URL routing (e.g. 'Atlanta, GA' + condo + for_sale → /atlanta-ga/condos-for-sale/). Parses the embedded Schema.org JSON-LD to return each listing's address, price, beds/baths, sqft, primary photo, listing agent + brokerage, and the homes.com property URL. KNOWN CAP: homes.com server-renders ~40 listings per page; the response carries truncated: true + total_estimated when the market has more. To enumerate a busy market, price-band or sub-area your search until each segment fits under the cap. Read-only; safe to call repeatedly.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
sortNoSort order. Only "newest" is currently supported.
viewNoResponse shape: "compact" (default) drops fields the response already carries elsewhere; "full" returns every field this server understands. compact strips image/avatar URLs from the response; "full" returns Homes.com's payload untouched. No field projection: this server has no verified record of which Homes.com fields matter, and inventing one would risk dropping a field a caller needs.
limitNoMax listings to return (default 40, which is also the homes.com SSR page size). Passing >40 will still cap at the page size; the response will set `truncated: true` and `total_estimated` to homes.com's reported total.
locationYesFree-text location: city, ZIP, neighborhood (e.g. "Atlanta, GA", "Brooklyn, NY", "30311", "Park Slope")
price_maxNoUpper price bound in USD (inclusive). Emitted as homes.com's `?price-max=` filter. Pair with price_min to band a busy market under the ~40-listing SSR cap.
price_minNoLower price bound in USD (inclusive). Emitted as homes.com's `?price-min=` filter. Composes with property_type / listing_type. Must be <= price_max when both are given.
listing_typeNoSearch axis. Defaults to for_sale. "sold" returns recently-sold listings (useful for market context). "for_rent" returns rentals. "open_houses" returns listings with scheduled open houses. "new_construction" returns builder listings under /new-homes/.
property_typeNoRestrict to a specific homes.com property type. Composes with listing_type.

A4.6/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Beyond the readOnly/idempotent/openWorld annotations, the description discloses significant behavioral traits: it slugifies the location into homes.com's URL routing, parses embedded Schema.org JSON-LD, and exposes the known ~40-listing server-render cap with `truncated: true` and `total_estimated` flags. This gives the agent exactly the kind of nuance needed to anticipate result truncation and plan enumeration. It also confirms the read-only nature expectations, matching the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the purpose, then filters, then behavioral details. Every sentence contributes meaningful information about filtering, slugification, parsing, or the cap. It is somewhat longer than necessary—'Read-only; safe to call repeatedly' partly duplicates the annotations—but the additional structured details are dense and useful. Overall it is appropriately sized for the tool's complexity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description covers return values explicitly: parsed listing fields (address, price, beds/baths, sqft, primary photo, listing agent + brokerage, property URL) and the `truncated`/`total_estimated` flags. It also addresses the operational context of searching busy markets with a clear mitigation strategy. Combined with fully documented parameters and annotations, nothing critical is left for an agent to infer.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema covers all 8 parameters with descriptions, meeting the 100% coverage baseline. The tool description adds value beyond the schema by explaining that location is slugified (e.g., 'Atlanta, GA' → /atlanta-ga/condos-for-sale/), that price_min/price_max should be paired to band a busy market under the cap, and that parameters compose (property_type + listing_type). This enriches parameter understanding rather than merely repeating schema text.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a concrete verb-plus-resource statement: 'Search homes.com listings by free-text location (city, ZIP, neighborhood).' This clearly distinguishes the tool from siblings like homes_get_property (which targets a specific listing) and homes_get_by_address (which resolves exact addresses), and it states the core mechanism. It then names the optional filters, making the purpose unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description conveys clear context for when to use the tool: to search listings by a free-text location with filtering options. It also gives practical usage guidance around the 40-listing cap ('price-band or sub-area your search until each segment fits under the cap'). However, it does not explicitly route agents away from the tool toward siblings like homes_get_property for specific-listing lookups, so it stops short of full when/when-not guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
