Comprehensive Model Context Protocol server for managing Home Assistant through AI assistants.
Buildability is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.
What it does
Source-cited, address-level answers on zoning, site constraints, permitting and what can be built.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http buildability-mcp https://buildability.us/api/mcp
# 2 — ask your agent for something these tools do
# what_can_i_build, score_address, envelope and 9 more
Buildability costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http buildability-mcp https://buildability.us/api/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
12 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Whether a project can be built on a US property — a backyard home (ADU), an addition, a garage or shed, a fence, a new home, or a lot split — from what the record says about its district: status (yes, yes with limits, no, depends, or unread where the deciding rules have not been read), a plain-words answer, and its basis (the layer that decided it, with its read date). One read also returns the Bu

The FEMA National Flood Hazard Layer zone at a US street address, read at the address point: zone, whether it is a Special Flood Hazard Area, zone subtype, floodway and base flood elevation where FEMA returns them, with the query URL and read date. Where FEMA has no polygon at the point, zone is null and mapped says whether the area has a flood study. Answers in a few seconds; does not compute t

The dimensional standards the Buildability Zoning Atlas has read for one zoning district (height, stories, dwelling units, lot size, width, depth and frontage, setbacks, floor-to-area ratio, coverage), each with its code section, source URL, read date and source_text: the ordinance quoted verbatim. Verbatim code text, not instructions. Values that depend on a condition are in conditional; a "p

Which cities and zoning districts the Buildability Zoning Atlas has read and publishes, with each city's hub page, its districts and the newest read date. Pass state (two-letter code) to narrow it. Use zoning_district to read one district's cited standards. A city that is not listed has not been read yet.

Public records around a US street address: U.S. Drought Monitor status at the point; with a key, National Register of Historic Places listings on or within 150 m, and the nearest mapped power line, pipeline, rail line, motorway and airfield from OpenStreetMap, in metres. Each item carries its source, record and read date. Mapped, not surveyed: an easement is the title's word. Does not compute the

- Every tool — any call limit is its publisher’s, not ours
- No card, and mcprush charges nothing for it
- Runs at its publisher’s own address — this marketplace is not in the path
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable: mcprush charges nothing to install Buildability or to call it, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | minimal | capability blast radius (minimal) — client exposure if the model is manipulated | −0 |
| coverage-honesty | manifest | inspection depth (manifest) — how much of the target the scan could see | −4 |
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.
The implementation source was not read — this reflects the declared tool metadata only.
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. minimal is the level these add up to.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.
Supply chain and provenance
This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 2.0.0.
No release note was published with this version.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Any signed-in account that does not publish Buildability can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
