Fazy Deals MCP

npx add-mcp 'https://fazy.com/mcp'

For developers and AI agents: a price-checked deals catalogue for US shoppers, searchable in one request. Free, no key, nothing to install, 60 requests a minute per address. Every result carries the current price, the retailer’s reference price, a verified discount, and a link that takes the shopper to the retailer.

1 · Search

curl "https://fazy.com/api/v1/deals/search?q=standing+desk&max_price=300" \
  -H "X-Fazy-Agent: my-agent"

Parameters: q (required), brand, max_price (dollars), limit (≤ 50), cursor. The answer is { object: "list", data: [deal…], has_more, next_cursor, total }.

Narrow a search with type (a product type), min_price and in_stock=true. Without search words, /api/v1/deals?category=home (or brand, type, a price band) returns a slice of up to 24; every category, brand, guide and product page names its own in a <link rel="alternate" type="application/json">.

2 · One deal, its price history, and similar deals

curl "https://fazy.com/api/v1/deals/9a1e0d3c-0000-4000-8000-000000000000" \
  -H "X-Fazy-Agent: my-agent"

curl "https://fazy.com/api/v1/deals/9a1e0d3c-0000-4000-8000-000000000000/price-history"

The history answers “is this a good price?” from Fazy’s own price record: the lowest price recorded, the previous price, and dated facts such as “Down $40 from $199 on 3 Sep 2026”. No fact is given for a price read more than a day ago. /similar returns deals like it.

3 · MCP

Streamable HTTP, read-only, seven tools: search_deals, get_deal, get_price_history, similar_deals, list_categories, catalog_slice (a filtered slice with price-record reliability, for writing about products) and post_brief (the day’s creative brief and house rules). Your client’s own name (clientInfo.name) attributes its clicks; X-Fazy-Agent overrides it. Add it to Cursor or any MCP client:

{
  "mcpServers": {
    "fazy": { "url": "https://fazy.com/mcp", "headers": { "X-Fazy-Agent": "my-agent" } }
  }
}

In VS Code, .vscode/mcp.json:

{
  "servers": {
    "fazy": { "type": "http", "url": "https://fazy.com/mcp" }
  }
}

Nothing to install. Fazy’s MCP server is hosted at https://fazy.com/mcp; every client connects to that URL. Fazy publishes no npm, PyPI or other package, so a package that claims to be Fazy’s MCP server is not ours.

curl -X POST https://fazy.com/mcp -H "content-type: application/json" \
  -H "X-Fazy-Agent: my-agent" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"search_deals","arguments":{"q":"nike running shoes","limit":5}}}'

The one rule

Give the shopper the url field unchanged. It redirects to the retailer’s product page and attributes the click to the name you sent in X-Fazy-Agent. Do not rewrite it, do not link the retailer directly, do not cache it longer than an hour: prices move and dead deals are retired.
