In the chat, type
@followed by the MCP server name and your instructions, e.g., "@@getfacade/mcp Turn this photo into a facade design and order a cost estimate"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
@getfacade/mcp
MCP server for GetFacade.ai: an agent creates a building, uploads a photo of it, gets the exterior designed, priced and documented, without a human in front of a screen.
Each design is worked out for the country the building stands in: materials that are applicable there, manufacturer products that are actually sold there, and the technical build-up behind the surface. The render shows that on the photo of the house.
The estimate and the album come from the same design:
The estimate prices it line by line, in materials and labour, at what those materials cost in that country.
The album documents it for the crew that builds it: the build-up of the facade, safety notes and the norms behind them.
The server is a thin wrapper over the public GetFacade API. It stores nothing, caches nothing and decides nothing: every rule (pricing, admission, the colour grammar, every message) stays on the server, and the wrapper only carries calls and answers.
Connect by URL
Most clients connect without installing anything. Add a custom connector with this URL and sign in to your GetFacade account when asked:
https://app.getfacade.ai/mcpClaude (claude.ai and desktop): Settings → Connectors → Add custom connector.
Claude Code:
claude mcp add --transport http getfacade https://app.getfacade.ai/mcpChatGPT, Cursor, VS Code and other MCP clients: add a remote (HTTP) server with the same URL.
On the sign-in screen you set a spend cap for the connection. It spends tokens from the agent wallet of your account and never buys tokens on its own. The connection appears among your agent keys in the app, where it can be revoked at any time.
A photo attached to a chat has no link the connector can read. create_building returns
photos_page, the building's photo page in the app: add the photo there, and list_photos picks
it up. A direct public link to an image works with upload_photo as well.

Run locally
The package below runs the same tools on your own machine with an agent key. Use it for automation, or when the photos are files on that machine.
Requirements
Node.js 20+
An agent API key. Issue one for yourself at app.getfacade.ai → Account → Settings → API. The value is shown once and cannot be recovered; each key carries a hard spend cap.
Agent access is paid. There are no trial credits in it: the key spends from the agent wallet, and without a balance the first paid call is refused with an explanation. An active Pro Plan fills that wallet up to 1,000 credits once per billing period; past that, credits are bought.
Setup
Claude Desktop / any MCP client, mcpServers section:
{
"mcpServers": {
"getfacade": {
"command": "npx",
"args": ["-y", "@getfacade/mcp"],
"env": { "GETFACADE_API_KEY": "your-key" }
}
}
}To run a checkout instead of the published package, point the client at it:
"command": "node", "args": ["/path/to/mcp/src/index.js"].
Variable | Required | Default |
| yes | — |
| no |

Messages, including refusals, come from the service in the language of
GETFACADE_LANG. Set it to the language the answer should be read in.
Tools
Tool | What it does |
| Creates a building. The name is unique per account. Say where it stands, or the place is inferred from the connection the call arrives on. |
| Takes a file path (local) or an image link (URL connection). Registers the file, uploads the bytes, confirms, waits for the answer: a view to design from, a drawing or reference kept with the building, or a refusal with the reason. |
| The views of a building, including photos added in the app. |
| Creates a design and queues its render. Returns a job id. |
| Changes a finished design in words. Every step after the first. |
| Polls one render, estimate or album. |
| Recent jobs across the account, unfinished first. |
| Designs of a building with their renders and finished picture. |
| Orders a cost estimate for chosen renders. |
| Orders the PDF album for chosen renders. |
| Enlarges a finished render. Costs tokens, asynchronous. |
| The estimate itself: totals, assumptions and every line. |
| Adds one line to an estimate. |
| Edits one line of an estimate. |
| Removes one line from an estimate. |
| Deletes one render. The main render's design returns to draft. |
| Deletes one design with the renders under it. |
| Deletes a building with everything under it. |
| The packages this account can buy. |
| Refills this key's wallet. Local package only. See below. |
| Agent wallet, key cap, and whether the next paid call will be accepted. |
| Reports a defect in this API. Free, and works on an empty wallet. |
Rendering is asynchronous: start_design, refine_design, order_estimate and order_album return a job id
immediately, and get_job reports when it is done. A finished estimate reads ready where a
render and an album read completed. The only call that waits is upload_photo, which polls
until the answer is in.
A paid call is never ordered twice
start_design, refine_design, order_estimate, order_album and upscale_render cost
money, and the charge follows the job that gets created. If one of them times out, the honest
question is whether the job exists, and the agent cannot answer it from where it stands.
So this server answers it instead. Every paid call goes out under a name of its own
(Idempotency-Key), and this server, not the agent, retries it under that same name when the
connection fails or when the API says the first attempt is still running. The API recognises
the repeat and hands back the original job, so a timeout costs one design, not two.
Nothing about this reaches the tool arguments: ordering the same design twice on purpose stays possible, because two calls are two names. What is gone is the accidental second order.
The API requires that name on every paid call made with an API key, so calling it without this wrapper means sending the header yourself. The reference is at getfacade.ai/agents.
What the key can reach
A key is a bearer secret that lives in your agent's config, so its reach is the published agent
surface and nothing else: buildings, photos, designs, renders, estimates, albums, the jobs list
and the API wallet. Anything outside that answers 403 AGENT_SURFACE_FORBIDDEN, including the
account's own sign-in settings, its subscription and its payment history. Changing those, and
issuing or revoking keys, is done by a person signed in to the app.
The reference is at getfacade.ai/agents.
Results are permanent public links
A finished render (result_url, main_render_url) and a finished album (result_url) are
served from stable URLs: no signature, no expiry. An assistant can hand one straight to a
person as the answer to "show me the result", with nothing to refresh and no second call.
The honest half of that: because the link is unsigned it asks nobody for permission, so it
keeps working for whoever it is forwarded to, and it cannot be recalled afterwards. Share it as
deliberately as any other link that is public forever. GET /renders/{render}/download is a
different thing — a short-lived signed URL with a filename, for saving the file rather than for
sharing it.
Deletions are soft on the server: a person can undo them in the app, this server cannot.
buy_tokens works only if the key was issued with purchasing enabled (a switch on the
issue screen), and only up to what the key may still spend — a purchase never lifts the key's
own spend cap. It answers charged when the payment provider took it from a saved payment
method, or requires_human with a checkout_url for a person to open. Either way the tokens
are credited when the payment is confirmed, so poll get_balance.
Issuing keys and buying a subscription are deliberately absent: a key that can issue itself a key has no ceiling, and a subscription is bought by a person, in the app.
License
MIT (see LICENSE) — this wrapper carries calls and answers and nothing else, so there is
nothing in it to keep closed. The GetFacade service it talks to is a separate matter: using it
is governed by the terms at getfacade.ai/terms, and a key is
issued to an account, not to this package.
Development
npm install
npm test # smoke test against a stub of the APItest/live-journey.mjs drives the whole journey through a real MCP client against a real API
with a real key. It is not part of npm test, because it spends actual credits; the header of
the file says how to run it.

Available Tools
21 toolsadd_estimate_lineAdd a line to an estimateA
Add one line to a generated estimate. unit must be a display code of the estimate's own measurement system — read an existing line to see which codes it uses rather than guessing. Totals are recomputed by the server.
Inputs: name (required), section (required), quantity (required), unit_price (required), +3 more.
buy_tokensBuy tokens for this keyA
Buy one token package for this key's wallet. Only works if the key was issued with purchasing enabled, and only up to what the key may still spend — a purchase cannot lift the key's own spend cap. The answer says charged when the payment provider took it from the saved payment method, or requires_human with a checkout_url a person has to open. Either way the tokens arrive asynchronously: poll get_balance.
Inputs: package (required).
create_buildingCreate a buildingA
Create a building (a house to design). The name must be unique within the account, max 50 characters — reusing a name is refused, so pick a distinct one instead of retrying the same. goals is the free-form brief (max 10000 chars).
Inputs: name (required), goals, construction_region.
delete_buildingDelete a buildingADestructiveIdempotent
Delete a building with everything under it: photos, designs, renders, estimates and albums. Deletion is soft on the server side and can be undone by a person in the app; this tool cannot undo it. Tokens already spent are not refunded.
Inputs: building_id (required).
delete_designDelete a designADestructiveIdempotent
Delete one design (concept) of a building, with the renders under it. Deletion is soft on the server side and can be undone by a person in the app; this tool cannot undo it.
Inputs: design_id (required), building_id (required).
delete_estimate_lineRemove a line from an estimateADestructiveIdempotent
Remove one line from a generated estimate. Totals are recomputed by the server.
Inputs: line_id (required), estimate_id (required).
delete_renderDelete a renderADestructiveIdempotent
Delete one render. Deleting the main render of a design returns that design to draft, so it can be rendered again without creating a new one. Deletion is soft on the server side and can be undone by a person in the app; this tool cannot undo it.
Inputs: render_id (required).
get_balanceCheck the agent walletARead-only
What this key can still spend: the api-scope balance of the account and the cap of this key. is_admissible is the server's own answer to "will the next paid call be accepted" — read it instead of comparing the numbers yourself.
Inputs: no named parameters.
get_estimateRead an estimateARead-only
The finished estimate: its totals, the area and duration it assumes, and every line with its quantity, unit and price. This is the only way to see what was estimated — get_job reports the status of an estimate, never its content. The unit of a line is the display code to reuse in add_estimate_line.
Inputs: estimate_id (required).
get_jobCheck one jobARead-only
Poll one queued job. kind says what it is: a render, an estimate, or an album (albums are listed per design, so an album lookup needs design_id). The finished status differs by kind: a render and an album read completed, an estimate reads ready. Stop polling on any of those and on failed, where error says what went wrong and error_code names it; repeat that reason as it stands instead of composing one. A render and an album report expected_seconds, how long that job usually takes end to end, so the wait between polls can be paced by it; an estimate does not, and reads null. The result_url of a finished job is a permanent public link: no signature, no expiry, so it can be handed to a person as it stands. It also keeps working for anyone it is forwarded to and cannot be recalled, so pass it on as deliberately as any other shared link.
Inputs: job_id (required), kind, design_id.
list_designsList designs of a buildingARead-only
All designs of a building with their renders. This is where the render ids for order_estimate, order_album and refine_design come from — main_render_id is the finished render of a design, null while nothing has finished, and main_render_url is its permanent public link (no signature, no expiry, safe to hand to a person, and not recallable once shared). Per-render state is not here: poll get_job for that.
Inputs: building_id (required).
list_jobsList recent jobsARead-only
Recent jobs across the account — renders, estimates and albums in one list, unfinished ones first. Use it to catch up after a restart: each row carries the kind and design_id that get_job asks for, and the building_id the job belongs to. Use get_job to poll a single known job.
Inputs: kind, limit.
list_token_packagesList the token packagesARead-only
The packages this account can buy, with their price and how many tokens each carries. Read this before buy_tokens instead of assuming a ladder — the packages and their prices change.
Inputs: no named parameters.
order_albumOrder a PDF albumA
Document the design as a PDF album (the blueprint document) for the renders you name: the materials, the build-up of the facade, safety notes and the regulatory references behind them. This is the document a crew builds from. Name the estimate_id of the estimate whose prices belong in it: without one the album takes the newest finished estimate of the design, which is not necessarily the one that was just ordered. Requires a completed main render on that design, otherwise the API refuses with an explanation. requirements is not honoured on every account: when it is not, the album is still made and notices says so, in the API's own words. The finished album is a permanent public link, so it can be handed to a person as it stands, and it stays readable for anyone it is forwarded to.
Inputs: design_id (required), render_ids (required), language, estimate_id, +3 more.
order_estimateOrder a cost estimateA
Price the design, line by line, in materials and labour, for the renders you name. The figures come from the design itself: what the specified materials and build-up cost in this country. Currency and measurement system default to the building's country and the written text to the account language; do not guess any of them, omit them unless the caller asked for a specific one. The money follows the house, the words follow the reader: a building in one country can be priced in its own currency and still be written up in the language the person asking reads.
Inputs: design_id (required), render_ids (required), building_id (required), currency, +3 more.
refine_designRefine a designA
Revise a finished design in words: "put a canopy over the front door", "make the roof darker". The revision is applied to the finished design, so what is not mentioned stays as it is — this is the tool for every step after the first, not start_design. Give it either the render_id of the picture to change (the job id start_design returned) or the design_id (with building_id) of the design whose finished main render should be changed. The parent render must be finished; refining an unfinished one is refused. Queues a render and returns a new job id, plus the design_id the result lands in (the server keeps every step as its own design, so the previous picture is never overwritten). Styles, colors and brands are optional here: pass them only to change them.
Inputs: instruction (required), seed, colors, design_id, +5 more.
report_problemReport a problem with this APIA
Report something wrong with this API itself: a field that is documented but never arrives, a refusal whose wording leaves no way forward, a call that only works on the second try, a result that does not match what was asked for. Free, and it works on an empty wallet, so a refusal can be reported the moment it happens. This is not the way to reach a person about an account or a charge, and no reply comes back through it; what comes back is a reference to quote. Say what was attempted, what was expected and what happened instead, and put the tool name and the ids in context so the report can be traced.
Inputs: message (required), context, category.
start_designStart a design renderA
Design the exterior of this house on a chosen view, and show the result as a picture. The design is worked out against the building's country: which materials are applicable there, which manufacturer products are really sold there, and what the build-up behind the surface is — the render is how that decision is shown, not a picture made for its own sake. Creates a new design (concept) and queues the work; returns a job id to poll with get_job. prompt is the free-form wish for this design ("a modern facade with a wide porch"). Colors accept the same strings the apps use: "palette:1", "paint:412", "siding:88@double-4-dutchlap" or "#RRGGBB" — order carries the 60/30/10 role, the first entry is the dominant wall color; brand_selections names real manufacturer products: "siding:brand:12", "siding:line:40@double-4-dutchlap", "paint:product:412". Omit seed unless reproducing an earlier render. To change a design that already rendered, use refine_design instead of starting another one.
Inputs: view_id (required), building_id (required), seed, colors, +4 more.
update_estimate_lineEdit a line of an estimateADestructiveIdempotent
Change one line of a generated estimate — its name, quantity, unit, unit price, category or section. Only the fields passed are changed. Totals are recomputed by the server.
Inputs: line_id (required), estimate_id (required), name, unit, +4 more.
upload_photoUpload a photo of the buildingA
Upload an exterior photo of the building and wait for it to be validated. Three legs: register the view, PUT the bytes to storage, confirm. Validation is asynchronous; the result says whether the photo was accepted, and a rejected photo cannot be rendered. The wait is bounded: a pending answer means validation is still running, and calling this again with the same file resumes it on the same view rather than uploading a second copy.
Inputs: file_path (required), building_id (required), wait_for_validation.
upscale_renderUpscale a renderA
Enlarge a completed render to a higher resolution. Costs tokens like a render and runs asynchronously: poll the returned job with get_job. A render that is already upscaled, or not finished yet, is refused by the API with an explanation.
Inputs: render_id (required).

TDQS
Scored across 21 tools
Each tool targets a distinct resource or action: jobs are polled with get_job, renders are listed through list_designs, new designs use start_design and revisions use refine_design. Even adjacent tools like order_estimate and order_album are clearly separated by output.
All tool names follow a consistent snake_case verb_noun pattern: list_*, create_*, get_*, delete_*, *_design, and *_estimate. The vocabulary is uniform and predictable.
21 tools is on the heavy side for a single server, and several resources have many small operations such as the estimate line CRUD. That said, each tool has a defensible role, and the breadth comes from the multi-stage facade workflow.
The core lifecycle is well covered: building creation, photo upload, starting and refining designs, rendering, estimating, reversing, albums, and token management. Minor gaps remain, such as no list_buildings or update_building, but an agent can work around them.
