Tera Studio

About

Tera Studio helps people sing. It looks up the key, tempo and typical vocal range of well-known songs by title, analyses a song file in the browser to find its key and BPM, and shifts a song up or down by up to 6 semitones to fit a voice.

It also explains how to hear a song sung in your own voice on terastudio.co. This tool returns steps and a link and creates nothing. Files chosen in the browser tools are processed locally and never uploaded. The hosted endpoint needs no sign-in or API key.

HTML

<a href="https://mcp.tc/i/tera-studio"><img src="https://mcp.tc/i/tera-studio/badge.svg" alt="Tera Studio 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/tera-studio.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/tera-studio" title="Tera Studio 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).

What each field means

AI prompt

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

Markdown

Add the mcp.tc card for Tera Studio, 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/tera-studio.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="tera-studio"><a href="https://mcp.tc/i/tera-studio">Tera Studio 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).
