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 →
Supply Chain Security87
- No malware found by supply-chain analysis.Pass
- Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency45
- 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 (MIT).Pass
- Actively maintained (last published 114 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability44
- 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Fail
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 430 tokens (~143/item across 3 items; 2 tools + 1 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 Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
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
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 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.

First indexed and scored.
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.

Dependencies 95 packages
95 packages in the resolved dependency tree · 95 deprecated · 29 stale.
The dependency tree was only partially resolved, so these counts may be incomplete.
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.
detail ~59
Get full metadata for a document. Use IDs from search results.
| Name | Type | Req | Description |
|---|---|---|---|
| doc_id | string | yes | Document ID from search results (e.g. "md5:abc123...", "hn:19415066", "doi:10.1038/...") |
No output schema declared.
No examples provided.
search ~365
Search documents. Returns ranked results with title, author, year, description, url, id, score — not full content. Use URLs from results with fetch/browsing to read actual documents. Use when: user asks to research, find papers/books/articles, look up facts, find discussions, legal cases, or any "search for..." request. Strategy: use 2-4 keywords per query (English preferred). Pick the right type first. Try synonyms if few results. Search across multiple types to cross-reference. Use detail() for full metadata on promising results.
| Name | Type | Req | Description |
|---|---|---|---|
| cursor | string | — | Opaque pagination token. Use next_cursor from previous response. |
| limit | integer | — | Results to return (1-50). Trial max 10, Pro max 50. |
| query | string | yes | Search query — use 2-4 keywords for best results. English preferred unless searching non-English content. Try different keywords and synonyms if first attempt returns few results. |
| type | string | yes | Content type (required). academic: OpenAlex/arXiv/Semantic Scholar/DBLP | wiki: Wikipedia 18 languages | books: books/digital libraries | legal: Case Law/CourtListener/EUR-Lex | forums: HN/StackExcha… |
