Category Search and Retrieval
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security97
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server supports Client ID Metadata Documents, the current MCP client-registration mechanism. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability82
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 773 tokens (~128/item across 6 items; 1 tools + 5 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management33
- Stability observed for 10 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 1 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
hasdata_duckduckgo_serp_getSearchResults duckduckgo_serp: GET / ~441
Get DuckDuckGo Search Results Fetches DuckDuckGo SERPs for a query with region targeting (kl, or cc+setLang), safesearch (off/moderate/strict), device type, and token-based pagination. Returns organic results (title, url, snippet, displayed url, position, date, sitelinks, video metadata), ads, and the Search Assist AI answer. Use for SEO rank tracking, SERP feature monitoring, DuckDuckGo-specific visibility audits, and training/eval data for search agents.
| Name | Type | Req | Description |
|---|---|---|---|
| cc | string | – | The two-letter country code for the country to search from. Combined with `setLang` to form the DuckDuckGo region. Ignored if `kl` is set. |
| deviceType | string | – | Specify the device type for the search. |
| kl | string | – | DuckDuckGo region code in `<country>-<language>` form (e.g. `us-en`, `de-de`). Sets country and interface language at once; takes precedence over `cc`/`setLang`. Use `wt-wt` for no region. |
| nextPageToken | string | – | Opaque token returned in each response as `nextPageToken`. Pass it back (in place of `q`) to fetch the next page of results. It carries a pre-signed page URL bound to the original request's session,… |
| q | string | – | Specify the search term for which you want to scrape the SERP. Required unless `nextPageToken` is provided (which carries the query of the page it continues). |
| safeSearch | string | – | Adult Content Filtering option. |
| setLang | string | – | The preferred result/interface language code — usually two letters (e.g. `en`, `de`), with script-tag variants for some languages (e.g. `zh-hans`, `zh-hant`). Combined with `cc` to form the DuckDuckG… |

How do I install the HasData DuckDuckGo MCP server?
HasData DuckDuckGo is a hosted endpoint at https://mcp.hasdata.com/mcp?apis=duckduckgo, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.
