NSW Development Applications (x402)

What NSW Development Applications (x402) does

NSW Development Applications (x402) exposes NSW planning data through MCP tools for two related record types: development applications and complying development certificates (CDCs). The data comes from the NSW Department of Planning, Housing and Infrastructure's NSW Planning Portal. Address matching uses the NSW address register from NSW Spatial Services.

The server supports both record-level research and property-oriented questions. Agents can search by council, suburb, postcode, lodgement date, or location; retrieve a complete record by its Planning Portal number; resolve an address; and combine planning controls with nearby development activity.

How it works

Start with nsw_da_get_summary or nsw_cdc_get_summary to inspect available status, application type, and council filter values. These summaries also provide counts and are free to call. Search tools return up to 100 results, ordered by newest lodgement, with has_more indicating whether another page can be requested using an offset.

Nearby searches accept either a street address or latitude and longitude. Address input is matched against the official NSW address register, and results include distance in metres. nsw_da_resolve_address can be used first when an application needs the official matched address and coordinates.

Paid tools use x402 and charge USDC on Base. The first three paid-tool calls per day are free for MCP clients while a shared daily allowance remains. Failed calls, unknown application numbers, and address lookup failures are not charged. Without x402 support, later paid calls return payment requirements as an error result.

Tools and capabilities

• Summarize development application or CDC counts by status, application type, and council.
• Search applications or CDCs by council, suburb, postcode, lodgement date, and supported filters.
• Find nearby applications or CDCs within 2 km, ordered by distance.
• Retrieve a complete application or CDC record by its Planning Portal number.
• Resolve a NSW address to its official form and latitude/longitude.
• Produce a planning report containing zoning, height, floor space ratio, minimum lot size, heritage, special planning areas, and nearby records.
• Summarize development activity near an address, including totals, costs, dwelling counts, status and type breakdowns, largest projects, and recent records.

The planning report can include up to 10 applications and 10 CDCs on the site and within a requested radius. Development activity covers a configurable historical period and radius, subject to the tool's stated limits.

Limitations and notes

Search filters such as status, application type, development type, and minimum cost must be combined with a council, suburb, or postcode filter. Full records should be requested using identifiers returned by a search or nearby-search result.

Nearby tools cover a maximum 2 km radius. The development activity tool accepts a radius up to 2,000 metres and a history window up to 120 months; its default values are 500 metres and 24 months. Planning reports use a default 200-metre radius and allow up to 500 metres.

Planning reports do not include council development control plan controls such as setbacks. Development activity sets capped when more than 2,000 records of one kind match, in which case its summary uses the nearest matching records.
