SAAX Protocol

About

SAAX Protocol is a vendor-neutral commitment lifecycle layer for agentic commerce. Its tools discover routable capabilities and suppliers, prepare signed nonbinding proposals, accept them into commitments, submit and verify evidence, raise and resolve disputes, and let an independently authorized agent resume a commitment after the original worker stops.

The server runs as a hosted streamable HTTP endpoint at saax-protocol.com/mcp. Read-only discovery tools work without sign-in or an API key. Lifecycle actions require an EIP-712 authority proof, and a few tools require an active SAAX Premium subscription. The vendor labels live mainnet payments as public beta and escrow custody as testnet-only.

HTML

<a href="https://mcp.tc/i/saax-protocol"><img src="https://mcp.tc/i/saax-protocol/badge.svg" alt="SAAX Protocol 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/saax-protocol.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/saax-protocol" title="SAAX Protocol 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 SAAX Protocol card to your site.

Markdown

Add the mcp.tc card for SAAX Protocol, 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/saax-protocol.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="saax-protocol"><a href="https://mcp.tc/i/saax-protocol">SAAX Protocol 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:
