Arugula

Arugula

Offers that fit, wherever people ask.

Arugula is a matching engine. Someone says what they want, in their own words, in their assistant, on a website or in a chat. Arugula matches the request on meaning against merchants' offers and returns the ones that fit, best first. Each offer comes with its price, a one-line reason why it fits, and a link to buy from the merchant.

• Ranked by fit only. Nobody can pay to be placed higher.
• Commission, disclosed. Arugula may earn a commission if you buy through these links, at no extra cost to you. Every list of offers says so.
• No account needed. Every surface below works without signing up.
• When nothing fits, nothing is shown.

Where to use it

MCP server

https://mcp.arugulanet.com/mcp: Streamable HTTP. No key and no sign-in.

Each client below has its own address, ending in ?ch=. That tag only tells us which kind of client sent a request, so we can see which ones people use.

Claude (web and desktop): Settings, then Connectors, then Add custom connector, with https://mcp.arugulanet.com/mcp?ch=claude-connector. Custom connectors are available on some Claude plans only.

Claude Code:

claude mcp add --transport http arugula "https://mcp.arugulanet.com/mcp?ch=claude-connector"

Cursor: add this to ~/.cursor/mcp.json (every project) or .cursor/mcp.json (one project). This repository is also a Cursor plugin (.cursor-plugin/plugin.json and mcp.json).

{
  "mcpServers": {
    "arugula": {
      "url": "https://mcp.arugulanet.com/mcp?ch=cursor"
    }
  }
}

One-click install, if your system opens cursor:// links:

cursor://anysphere.cursor-deeplink/mcp/install?name=arugula&config=eyJ1cmwiOiJodHRwczovL21jcC5hcnVndWxhbmV0LmNvbS9tY3A/Y2g9Y3Vyc29yIn0=

Open WebUI (0.6.31 or later): Admin Settings, then External Tools, then + Add Server. Type MCP (Streamable HTTP), URL https://mcp.arugulanet.com/mcp?ch=open-webui, Auth None. The URL must be reachable from the Open WebUI server.

LibreChat: in librechat.yaml:

mcpServers:
  arugula:
    type: streamable-http
    url: https://mcp.arugulanet.com/mcp?ch=librechat
    title: Arugula
    description: Find offers that fit what you want, ranked by fit only.
    timeout: 60000

Jan: Settings, then MCP Servers, then + Add MCP Server. Name arugula, transport HTTP, URL https://mcp.arugulanet.com/mcp?ch=jan. Turn tools on for the model you use.

LM Studio (0.3.17 or later): Program tab, then Install, then Edit mcp.json, and add this inside mcpServers:

"arugula": {
  "url": "https://mcp.arugulanet.com/mcp?ch=lm-studio"
}

Any other MCP client: use https://mcp.arugulanet.com/mcp with the Streamable HTTP transport and no authentication.

The entry for the official MCP registry is server.json (com.arugulanet/arugula).

Telegram

Open @ArugulaNetBot and say what you want. To use it with others, add it to a group. To use it in any chat, type @ArugulaNetBot followed by your request.

Site search

One line on any page with a search box. When a visitor searches, offers that fit show up under your search form. The script sets no cookies.

<script async src="https://api.arugulanet.com/embed/v0.5.2/search.js"
        integrity="sha384-VUDq6tLbkK5ID6JJ8KnwaPN9dWB5VCKUxZ/r7gJTZdpXxn+yqTE2S7AKsVNmuXGD"
        crossorigin="anonymous" data-channel="site-search"></script>

It finds your search box by itself: input[type=search], a search form, or an input named q, s, search or query. All of these attributes are optional:

The hashes for each release are at https://api.arugulanet.com/embed/v0.5.2/integrity.json. Each release path never changes.

Shopify

In your theme, open Edit code, then layout/theme.liquid, and paste this just before </body>:

<script async src="https://api.arugulanet.com/embed/v0.5.2/search.js"
        integrity="sha384-VUDq6tLbkK5ID6JJ8KnwaPN9dWB5VCKUxZ/r7gJTZdpXxn+yqTE2S7AKsVNmuXGD"
        crossorigin="anonymous" data-channel="shopify"></script>

It attaches to your store's search the same way as site search.

Google Tag Manager

The tag template is template.tpl in this repository. It loads the site-search script.

1. In GTM, open Templates, then New under Tag Templates.
2. Open the menu at the top right, choose Import, and select template.tpl. Save.
3. Add a new tag of type Arugula that fires on All Pages. Publish the container.

You can also download the template as a ZIP from https://api.arugulanet.com/arugula-gtm-template.zip.

WordPress

Download arugula-wordpress.zip. In WordPress, open Plugins, then Add New, then Upload Plugin. Choose the file and activate it. It attaches to your site's search with nothing to set up. The plugin's readme.txt lists everything it sends and stores.

Cloudflare Zaraz and Workers

Three ways in, all in cloudflare/:

1. Zaraz Custom HTML: add a Custom HTML tool with the site search snippet, using data-channel="zaraz", and give it a Pageview action.
2. Zaraz Custom Managed Component: deploy cloudflare/component as a Worker with npx managed-component-to-cloudflare-worker ./index.js arugula, then add it under Third-party tools.
3. Cloudflare Worker for sites on Cloudflare without Zaraz: cloudflare/worker adds the script at the edge (npx wrangler deploy).

The script runs once per page even when Zaraz fires on every single-page navigation.

Chatbots

A bot you already run can forward a user's message to Arugula and show the offers that come back:

POST https://api.arugulanet.com/v1/partner/intents
Authorization: Bearer <partner key>

{"text": "a linen sofa under S$1,500", "user_id": "<your user's id>"}

The answer has offers, each with a tracked_url, and a ready-made text reply. For Chatwoot, set the agent bot's webhook to https://api.arugulanet.com/hooks/chatwoot/<partner id>?key=<partner key>. To get a partner key, open an issue.
