Trust breakdown (6 categories)

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 Security98

No malware found by supply-chain analysis.Pass
A known CVE affects extract-zip, but no fixed version has been published, so there is nothing to upgrade to. View diagnostics → Partial
No install/post-install scripts declared.Pass
49 of 173 dependencies flagged as unhealthy. View diagnostics → Partial

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 (MIT).Pass
Actively maintained (last published 0 days ago).Pass
Publishes a security disclosure policy (SECURITY.md).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 956 tokens (~136/item across 7 items; 7 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 Management0

Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified

Tool Coverage90

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
71% of tool parameters carry a description.Partial

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.
