Cassette

About

Cassette is a store of games that run in the browser. This server lets an assistant search the catalog, read the facts for one game, find similar games and list genres and tags. Each game comes with devices, players, session length, age rating, download size, account needs, a store page and a play link. Hosted games are returned first, then community games listed from other sites.

The server is a hosted, read-only endpoint over streamable HTTP. No sign-in or API key is needed. A separate Cassette server handles publishing games and is not part of this one.

Embed

Show Cassette 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.

[![Cassette on mcp.tc](https://mcp.tc/i/cassette/badge.svg)](https://mcp.tc/i/cassette)

HTML

<a href="https://mcp.tc/i/cassette"><img src="https://mcp.tc/i/cassette/badge.svg" alt="Cassette 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/cassette.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/cassette" title="Cassette 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).

AI prompt

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

Markdown

Add the mcp.tc card for Cassette, 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/cassette.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="cassette"><a href="https://mcp.tc/i/cassette">Cassette 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
[![Cassette on mcp.tc](https://mcp.tc/i/cassette/badge.svg)](https://mcp.tc/i/cassette)
```

   Before

   Cassette is a store of games that run in the browser. Use these tools to help a person find one. When the request already gives you something to search with (a device, an age, a mood, a game they liked), search first and ask afterwards what would narrow it; ask first only when it gives you nothing. Put the person's own words in `query` and their limits (device, age, price, multiplayer, download size) in the filters. Read each game's facts before you recommend it, offer one to three games with their play links and what could stop the person (a keyboard, an account, a big download), and if nothing fits, say so: never suggest a game these tools did not return. Community games are listed from other sites and play there.
