Buildability

About

Connects to the Buildability service, which scores US addresses and parcels from 0 to 100 using cited public data: zoning, FEMA flood, USGS seismic, USDA soil, EPA radon, USFS wildfire, utilities, terrain and lot shape. Tools cover live address scoring, parcel search, factor breakdowns, buildable envelopes, what-if scenarios, pro-formas and city market rankings.

It runs as a hosted streamable HTTP endpoint. Scoring a new address takes roughly 10 to 20 seconds. No sign-in or API key is needed for the main tools; the lot_surface tool requires a Buildability API key.

What you can do

• Score any US street address with live federal data
• Search scored parcels by text, score and Opportunity Zone
• Explain a score factor by factor
• Get buildable envelope: units, FAR, height, setbacks
• Run what-if scenarios such as upzoning or flood mitigation
• Pencil a development pro-forma for a parcel
• Rank metros on the City Buildability Index
• Read permit outcomes for a zoning district

Show Buildability in a README or on your site. Each embed links to this page, uses the server’s own URL, and sets no cookies. How embeds work

The card, the iframe and the JSON are in English. Add ?lang=it, fr, de or es to their address for another language.

[![Buildability on mcp.tc](https://mcp.tc/i/buildability/badge.svg)](https://mcp.tc/i/buildability)

HTML

<a href="https://mcp.tc/i/buildability"><img src="https://mcp.tc/i/buildability/badge.svg" alt="Buildability on mcp.tc" height="20"></a>

It follows the reader’s light or dark mode. Add ?theme=light or ?theme=dark to fix it, or ?style=compact to show the mark without the word.

Website card

HTML

<script src="https://mcp.tc/w/buildability.js" async></script>

The card appears where the tag is. Add data-theme="dark" or data-size="compact" to the tag to change it. The file holds everything it needs, so it makes no other requests and sets no cookies.

iframe

HTML

<iframe src="https://mcp.tc/embed/buildability" title="Buildability on mcp.tc" width="420" height="200" loading="lazy" allow="clipboard-write" style="border:0;border-radius:8px;max-width:100%"></iframe>

Use it on pages that don’t allow scripts. Add ?theme=light or ?theme=dark to the address to fix the colors.

JSON

The listing as data for your own pages and tools: name, tagline, the server’s own URL, tools and the “Add to” links. Any site can read it (CORS is open).

Paste this into an AI coding assistant, such as Claude Code or Cursor, and it adds the Buildability card to your site.

Markdown

Add the mcp.tc card for Buildability, an MCP server, to my website. It is one static script: no build step, no package to install, no cookies.

Put this tag where the card should appear. The card renders right before it:

```html
<script src="https://mcp.tc/w/buildability.js" async></script>
```

To show the card somewhere else, put this placeholder there and load the same script once, for example before `</body>`. Keep the link inside: visitors without JavaScript see it.

```html
<div data-mcptc="buildability"><a href="https://mcp.tc/i/buildability">Buildability on mcp.tc</a></div>
```

Options:
- `data-theme="light"` or `"dark"` on the tag or the placeholder fixes the colors. Without it, the card follows the visitor’s light or dark mode.
- `data-size="compact"` gives a smaller card without the tagline.
- The CSS variable `--mcptc-max-width` on the placeholder or a parent sets the width (default `520px`).
- `?lang=` on the script URL sets the card’s language: `en`, `it`, `fr`, `de` or `es`.

If the site has a Content Security Policy, allow `script-src https://mcp.tc` and `img-src data:` (the icon is inline).

For a README or other Markdown docs, use the badge instead:

```markdown
[![Buildability on mcp.tc](https://mcp.tc/i/buildability/badge.svg)](https://mcp.tc/i/buildability)
```
