What is DuckDuckGo's own AI answer for that query?
Search Assist opens with the definition and the date:
"Model Context Protocol (MCP) is an open standard introduced by Anthropic in November 2024 that lets AI apps connect in a standardized way."
It comes back in two forms, a short answer and an expanded one, with two sources attached.

Who is buying ads on DuckDuckGo for "model context protocol"?
Two advertisers on this query.

CData is bidding on the exact phrase, ServiceNow on the audience around it.

How do the DuckDuckGo results for that query look on mobile in Germany?
Same ten slots, but the encyclopaedia switches language.
Position 2 is de.wikipedia.org in the German market, where the US result was en.wikipedia.org.
Positions 1 and 3 stay on modelcontextprotocol.io.

FAQ
Before you wire it in
Do I need a DuckDuckGo account or API key?
No. The only credential is your HasData key. The tool reads the public results page a signed-out visitor sees.
How do I page through the results?
Each response returns a <code>nextPageToken</code>. Send that instead of <code>q</code> on the next call and you get the following page, with the query, the region and the safe-search setting already carried over. Send one or the other, not neither.
Do the search operators work?
Yes. <code>site:</code>, quoted phrases and the rest go through as typed, so an agent can narrow a query the same way a person would in the search box.
What is Search Assist?
DuckDuckGo’s own AI answer above the results. It arrives as its own block when the page shows one, so you can track whether a query triggers it and what it says without parsing the page yourself.
How fresh is the data? Is anything cached?
Every tool call fetches the page at that moment, so a ranking change from an hour ago is already reflected. Nothing is served from a cache.
Can I compare regions and devices?
Yes. <code>kl</code> selects the region and language pair, <code>deviceType</code> switches between desktop, mobile and tablet. Both are enums, so the agent picks a documented value rather than guessing a header.
How many calls can run in parallel?
One on the free tier, five on Startup, fifteen on Basic, and fifty on Growth. The larger Growth volumes raise it to 200, 300 and 500.
What happens when I run out of credits?
Nothing is charged on top of the plan. Calls stop until the billing cycle renews.
Does it work with Claude Desktop, Cursor, VS Code and Claude Code?
Yes, all four, plus anything else that speaks MCP over streamable HTTP. Claude Desktop connects through OAuth, and the rest take the URL and an API key header.
Is HasData affiliated with DuckDuckGo?
No. HasData is an independent service and is not affiliated with, endorsed by, or sponsored by DuckDuckGo, Inc. DuckDuckGo is a trademark of its respective owner.
