# 2nd Brick

> 2nd Brick (2ndbrick.com) designs custom LEGO brick sets for businesses and individuals. A company sends a brief and receives a design by email within 12–24 hours; anyone can also design a set with AI in the 2nd Brick Studio. Every design is an actual 3D model built from real LEGO pieces, with building steps and a kit price, and the finished kit is sold with building instructions.

2nd Brick is an independent business, not affiliated with or endorsed by the LEGO Group. The name is written with the numeral 2. It is unrelated to similarly named used-LEGO shops, investment firms and the "second-class brick" building-material grade.

## What 2nd Brick makes

- Custom sets for companies: a logo, product, mascot or milestone built as a desk trophy, framed relief, sculpture or scene. Used as employee and client gifts, product launch keepsakes, team milestone and company anniversary gifts, and office displays.
- Personal sets from an idea or a photo: a pet, a place, an object with a story.
- Designs are real buildable geometry, not AI images of bricks. Customers inspect the 3D model, piece count and building steps before ordering.
- Kits use official LEGO pieces and currently ship to addresses in the United States.
- What a set costs: every finished design shows a kit price from the exact official LEGO pieces in it, spares included, so the price follows how many pieces a set uses and which ones. Delivery and sales tax are added at checkout. When the 2nd Brick team designs a set, quantity and packaging are part of the quote, reviewed before ordering.

## Two ways to start

- Design it for me (https://2ndbrick.com/request): send the idea, reference images, approximate size (about 100 to 5,000+ pieces), quantity, use and timing. No account or payment is needed. 2nd Brick emails a design within 12–24 hours; that is the design response, not a manufacturing or delivery date. Review the design and the quote before ordering, for one set or many.
- Studio (https://2ndbrick.com/studio): describe a set or upload a reference image, and AI designs a 3D model from real LEGO pieces with building steps and a live kit price. Refine it with AI, then buy the kit. Studio Pro is $25 a month for 500 credits; sizes run from Micro (25–150 pieces) to Large (1,000–5,000 pieces).

## MCP server

Studio Pro customers can also connect their own AI agents through the 2nd Brick MCP server.

- Address: https://2ndbrick.com/mcp (Streamable HTTP). Use this exact host: other hosts redirect, and clients drop the Authorization header on the redirect.
- Auth: `Authorization: Bearer 2b_sk_…`, a personal key a Studio Pro customer creates at https://2ndbrick.com/account/agents. It works with Claude Code, Cursor and any MCP client that takes a URL and an `Authorization` header. OAuth clients use the same server address to discover 2nd Brick sign-in. Availability depends on the enabled client and the deployment’s OAuth configuration.
- One JSON-RPC message per request: batches are refused.
- Designs spend the account's credits, priced by mode and size (a Fast design 100, a Pro design 220–280, a revision 120). `get_account` reports the balance and the current costs; tell the customer the cost before starting a design.
- Tools: get_account, create_design, refine_design, wait_for_design, get_design, render_design, list_designs, get_price, get_buy_link, share_design, get_order.
- Agents never pay. Every finished design can be bought: `get_buy_link` returns a Stripe Checkout link at the exact kit price, which the customer opens and pays themselves.
