How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security0
- No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package.Unverified
- Known CVEs could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.Unverified
- Install-script risk not yet assessed.Unverified
- Dependency health could not be checked: this artifact ships no SBOM or dependency manifest, so there is no dependency list to read.Unverified
Provenance & Transparency48
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (AGPL-3.0-or-later).Pass
- Actively maintained (last published 104 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability70
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 640 tokens (~213/item across 3 items; 3 tools + 0 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 Management100
- No destabilizing schema changes in the last 30 days.Pass
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
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 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 current MCP spec version (2026-07-28).Pass
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

Diagnostic detail from the automated scan of this channel: what the scanner observed at each step, so you can see exactly where a check passed or failed. It is informational only and never changes the trust score.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

Background: How many MCP packages publish verified provenance →
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 →
autocomplete ~151
Get search query suggestions from SearXNG. Returns a list of autocomplete suggestions for the given partial query. Use this to discover relevant search terms before performing a full search. Best results come from 1-2 meaningful keywords (e.g., "python async"). Single characters return overly broad suggestions; full sentences return none. Makes an external API call to the configured autocomplete backend (e.g., Bing, Google). Not suitable for full web search (use search tool) or engine discovery (use engine_info tool).
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | yes | Partial query string to get suggestions for. Best results with 1-2 keywords (e.g., 'python async'). Single characters are too broad; full sentences return nothing. |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
engine_info ~75
Get available search engines and categories from the SearXNG instance. Returns the list of enabled engines grouped by category. Use this to discover what engines and categories are available before calling search with specific engines or categories filters. Response is cached for 5 minutes. Does not perform any web search — use the search tool for that.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
search ~414
Search the web using SearXNG metasearch engine. Aggregates results from 200+ search engines (Google, Bing, DuckDuckGo, Brave, etc.) with privacy. Returns results, answers, suggestions, corrections, and infoboxes. Use 'categories' to focus on specific content types. Use 'pages' for more results. Not suitable for autocomplete suggestions (use autocomplete tool) or discovering available engines/categories (use engine_info tool). Results are cached for 60 seconds.
| Name | Type | Req | Description |
|---|---|---|---|
| categories | string | – | Comma-separated category names to focus on (e.g., 'general,news,science'). Prefer this over 'engines' to narrow results — categories leverage multiple engines automatically. Call engine_info to disco… |
| engines | string | – | Comma-separated engine names to use (e.g., 'google,arxiv,wikipedia'). Only use when you need a specific source; otherwise prefer 'categories'. Overrides category-based engine selection when set. |
| format | string | – | Result detail level: 'compact' returns title/url/content only, 'full' includes engines/score/category/date/thumbnails |
| language | string | – | Search language code (e.g., 'en', 'zh', 'ja', 'de'). Filters results to the specified language. Omit to search all languages. |
| max_results | integer | – | Maximum number of results to return. Applied after aggregation across pages. |
| pageno | integer | – | Starting page number. Use with 'pages' for pagination. |
| pages | integer | – | Number of pages to fetch in parallel (multi-page fanout). Higher values return more results but increase latency. Use 2-3 for comprehensive research. |
| query | string | yes | The search query to use |
| safesearch | integer | – | Safe search level: 0=off, 1=moderate, 2=strict |
| time_range | – | – | Restrict results to those published within this time window. Omit for no time restriction. |
