Overview

AI-generated overview

Gage prices building designs in cold-formed steel framing through a fabricator network and can start a real fabrication project.

What you can do
  • Submit a floor plan or 3D house model to get a buildable steel framing quote
  • Price a building from a plain description, including which regional shop would fabricate it
  • Start a Gage project from a quote, creating it with the regional fabricator and emailing a private link
  • Review the quote, talk to the fabricator and follow the frame to delivery from that page
When to use it
Useful when someone has a house, ADU, cabin, garage, workshop or small commercial design and wants to know what cold-formed steel framing would cost, who would fabricate it, and how to get it built.
Requirements
Remote endpoint at buildwithgage.com over streamable HTTP; no local runtime or package. Public tools need no key. Partners may optionally send a Gage API key in the Authorization header as a Bearer token.
Before you install
The tools act on real projects: start_my_project creates a project with a fabricator and emails a private link to the person, so confirm before calling it. Quotes and project details are shared with the Gage fabricator network. An API key passed in the Authorization header is a secret and should not be exposed.

Installation

In SourceWeft

  1. Open Gage in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.buildwithgage%2Fgage/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

submit_design_for_quote

Submit a design for a CFS fabrication quote

Submit a building design to Gage and get back a real, buildable cold-formed steel (CFS) framing quote from the Gage fabricator network. Use this when you have generated or been given a floor plan or 3D house model and need to know what it costs to frame in steel, who would fabricate it, and how it breaks into panels. Give it structured geometry (levels, walls as start/end points, openings, roof) plus the build site ZIP and project type. It reduces the model to the quoting engine's inputs, checks whether the design can actually be auto-panelized, and returns: - a structural feasibility flag, - an itemized quote (steel, transport, engineering, subtotal, confidence band, fabricator and lead time), - a downloadable preliminary panelization package (panel count, panel footage and totals; the panel-by-panel schedule goes to the Gage fabricator that takes the job). It refuses rather than guesses. Geometry that is invalid or outside what the engine prices comes back as a structured error; a design that is legible but needs a structural decision (curved walls, a header over 12 ft, a cantilevered storey, tall walls) comes back with status "needs_human_review" and no price. A quote is only ever returned for a design that passed every check. Pricing, tonnage and fabricator routing are computed by Gage API v1, not by this tool. Panelization output is preliminary and unstamped; stamped shop drawings are issued by the assigned fabricator after a quote is accepted.

quote_my_building

Price a building in steel framing

Price a building in cold-formed steel framing from a plain description, through the Gage fabricator network: what it costs to have the frame fabricated and delivered, and which regional shop would build it. Use this when someone has designed a house, ADU, cabin, garage, workshop or small commercial building (in this conversation or elsewhere) and asks what it would cost to build, how to get it built, or whether it can be framed in steel. For example, "how much to build this 1,900 sq ft one-storey gable house near 84032" -> total_sqft 1900, stories 1, roof_type "gable", zip "84032". Only the size, storeys, roof and build-site ZIP are needed; ask the person for the ZIP if you do not have it. Anything else not given (ceiling heights, windows, doors, wall length, pitch, steel gauge) is filled with stated defaults and listed as assumptions. If you have exact walls and openings, submit_design_for_quote gives a tighter price. The price is the steel frame package: framing steel, engineering and delivery. It is not the whole house (no foundation, finishes or labour on site). The fabricator is named by region until they take the job. When the person wants to go ahead, call start_my_project with the quote id.

start_my_project

Start a Gage project

Start a real Gage project from a quote, so the person can get their building fabricated: Gage creates their project with the regional fabricator that priced it and emails them a private link to it. From that page they review the quote, talk to the fabricator and follow the frame to delivery. Nothing is charged by starting a project. Only call this when the person has said they want to go ahead, and only with a name and email address they have given you for this. Ask them first: "Shall I send this to Gage so a fabricator can take it on? I'll need your name and email." Set person_agreed to true only after they say yes. Use the quote_id from quote_my_building or submit_design_for_quote. The link goes to their email only; tell them to look for an email from Gage.
