Use dudils in Claude or ChatGPT

dudils has a free connector for AI assistants. Add it once and you can ask Claude or ChatGPT things like "find me a single storey four bedroom plan under $500k that fits a 12.5 metre wide block in NSW", and your assistant searches the real dudils catalogue: every plan architect approved, every plan with living areas that can face north. Each result links straight back to the plan page here. No signup, no API key, no cost.

Add dudils to Claude

This works on every Claude plan, including Free, which allows one custom connector. On a Team or Enterprise plan an owner adds it once under Organization settings, then Connectors, and each member then clicks Connect.

  1. In Claude, open Customize, then Connectors. Click + Add, then Add custom connector.
  2. Name it dudils, paste this URL and click Continue:
    https://www.dudils.com/api/mcp
  3. When it asks about signing in, choose No sign in, then click Add. dudils needs no account, API key or OAuth settings.
  4. In a chat, click the + button at the bottom left, open Connectors and check dudils is switched on. Then ask Claude about house plans.

Using Claude Code? One command: claude mcp add --transport http dudils https://www.dudils.com/api/mcp. Full details in Claude's connector guide.

Add dudils to ChatGPT

ChatGPT is harder. Adding your own connector needs a paid plan and ChatGPT in a web browser (not the phone app), and it sits behind a developer mode switch. OpenAI decides which plans get developer mode, and on a Business or Enterprise workspace an admin has to allow custom connectors first. If your account has no developer mode, Claude's free plan works instead.

  1. On chatgpt.com, open Settings, then Apps (some accounts still call it Connectors), then Advanced settings, and turn on Developer mode.
  2. Back on that page, choose Create, name it dudils and paste this URL:
    https://www.dudils.com/api/mcp
  3. Set authentication to none and save.
  4. In a new chat, open the + menu, choose Developer mode and switch dudils on. Then ask ChatGPT about house plans.

OpenAI renames these menus often, so yours may read a little differently. The current version is in OpenAI's developer mode guide.

What it can do

The connector gives your assistant three tools:

  • search_plans: the block search on our homepage, anywhere in Australia. Give it your build area, which side the street is on and any setbacks, plus bedrooms, bathrooms, car spaces, storeys, budget, state and dwelling type, and it returns the same plans the homepage shows.
  • search_by_address: give it a NSW street address and it reads the real block, works out which way it faces, and returns the plans that fit with their living areas facing north on it. The same search as typing the address on this site.
  • get_plan: fetch the full details of one plan, including its dimensions, price and builder.

Things worth asking:

  • "Find single storey 4 bedroom plans under $400k that fit a 12.5 m wide block in NSW."
  • "Which duplex plans fit a 15 m by 30 m corner block with the garage on the left?"
  • "Which 4 bedroom single storey plans fit 15 Lushington Street, East Gosford?"
  • "Compare the three cheapest 3 bedroom plans in Victoria and link me to each one."

One honest note: your assistant does the talking, and assistants can get things wrong. dudils only supplies real catalogue data, so always open the linked plan page before making decisions, and talk to the builder or an architect before committing to anything.

For developers and AI builders

The connector is a Streamable HTTP MCP server with open CORS and no authentication, so it also works from agents, scripts and any other MCP client:

Prefer plain HTTP? The same search is available as a JSON API at /api/search, and /llms.txt documents the full URL grammar and response shapes for AI agents. If you are screening NSW development sites, the Pattern Book screening tool pairs well with an assistant driven workflow.
