HtAG opens Australian commercial sales data to AI assistants through MCP

HtAG Analytics launched a new commercial sold-property search in its Developer Portal on 4 November 2026, giving developers and AI assistants self-serve access to Australian commercial comparable sales through a REST API and MCP. The move targets a market where published commercial sale prices are often missing, and it lets users query sold industrial, office, retail and other property types by natural language or API.

Why it matters: - Australian commercial comparable sales are hard to source because many listings are marketed as "contact agent" and do not publish a price. - The new search gives developers, valuers, brokers and AI assistants a direct way to find sold commercial property evidence. - HtAG positions the release as one of the first Australian commercial comparable-sales datasets available to AI assistants through MCP. - The launch adds self-serve, pay-per-row access to a market where comparable-sales data is usually sold through enterprise contracts.

What happened: - HtAG Analytics launched commercial sold-property search in its Developer Portal on 4 November 2026. - The data is available through a self-serve REST API and through MCP, the Model Context Protocol used by AI assistants such as Claude to call external tools. - The endpoint is GET /v1/property/commercial/sold/search. - The same search is also available as search_commercial_sold_properties on HtAG's MCP server. - HtAG said users can search in plain English through compatible assistants.

The details: - Searches can start from an address, an address key, or latitude and longitude. - The search radius extends up to 5 km, or users can search across a whole suburb. - Filters include category, tenanted investment or vacant possession, sale date, sale price, floor area and land area. - Results can be sorted by newest sale or nearest distance. - The category filters cover industrial, office, retail, showroom, medical, development land, hospitality and leisure, rural agribusiness, and other. - Each result can include address, distance from the search point, sold date, recorded sale price where disclosed, floor and land area, zoning and land use, year built and tenure. - When a price is shown, it is the recorded transfer-of-title price, not an asking price. - The service is billed per row from A$0.075, and the first 25 rows are free. - Rows are billed on HtAG's Enhanced tier at A$0.075 per row at list price, including GST. - Each account gets its first 25 rows free on each endpoint. - Linked annual HtAG Professional and Elite plans receive 90% off data rates. - Usage is capped at 10,000 billable rows per organisation per month. - Access is available self-serve at htagai.com, including a no-code Playground for browser-based searches.

Between the lines: - HtAG is betting that AI assistants will become a front end for property data discovery, not just a layer on top of text prompts. - The release also underscores how sparse public commercial-sale pricing remains in Australia. - In an HtAG sample of 274 commercial sales within 5 km of Sydney's CBD between 1 November 2025 and 4 November 2026, only 33 sales, or 12.0%, had a recorded sale price. - Victoria's rule requiring agents to publish sold prices within seven days took effect on 1 October 2026, but it applies to residential property sales. - HtAG is aiming at commercial and buyers' agents, valuers, commercial lenders and brokers, developers, and proptech teams building comparable-sales evidence into products. - The company says it is among the first in Australia to make commercial comparable sales available to AI assistants through MCP.

What's next: - HtAG says the endpoint currently covers sold comparable-sales data only. - Commercial leasing, rents, yields and for-sale listings are not included yet. - Sales with withheld addresses are also excluded. - HtAG's connectors are listed in Anthropic's Claude connector directory, which could broaden use by MCP-compatible assistants. - The company expects broader use by firms that need faster comparable-sales evidence for site assessment, lending and valuation workflows.

The bottom line: - HtAG is turning a hard-to-find slice of Australian commercial property data into a searchable product for both APIs and AI assistants.
