Parts library
Every part you've added, priced and ready to quote, build your library first, order when you're ready
Upload parts to your library or drag and drop, several at once is fine
DXF · DWG · SVG · AI · PDF · STEP · IGES · EPS up to 25MB, checked and priced on arrival, no quote needed
The shape stays the same, only its size changes. Holes and slots scale with it.

Taking you to secure payment…Your order is created. Keep this tab open while the payment page loads.
Customers
Open a customer’s workspace to quote on their behalf: upload their files, build the quote, set prices, then send it to them. Anything you add lands in their parts library. Buyers who paid without signing in show as guest checkouts, found by the email they gave at Checkout or the order number, and open read-only.

Any agent that speaks to a remote MCP server connects the same way, with the address
https://kerf.au/mcp
One with no browser to sign in with needs an API key instead, sent as Authorization: Bearer.
Whatever you connect appears below. It can price parts, build quotes and get the checkout link on this account. It never pays; the checkout link comes back to you. How it works
Writing a script, or running an agent with no browser to sign in with? You need an API key
A key does the same job as signing in, for code and for agents on a server or in CI. It is shown once; everything it makes appears in your quotes and orders.
