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 Security83

No malware found by supply-chain analysis.Pass
CVE check failed: a known medium-severity CVE affects @hono/node-server 1.19.17, reached via @modelcontextprotocol/sdk > @hono/node-server. A fixed version is available. View diagnostics → Fail
No install/post-install scripts declared.Pass
Only part of the dependency tree could be resolved (96 of 100), so this covers what we could see, not the whole tree. View diagnostics → Partial

Provenance & Transparency84

Source repository is publicly reachable at the declared URL. View diagnostics → Pass
Cryptographically verified build provenance (signed, bound to Mearman/mcp-wayback-machine). View diagnostics → Pass
License check failed: the license (CC-BY-NC-SA-4.0) isn't a recognized OSI-approved license. See how to fix → Fail
Actively maintained (last published 63 days ago).Pass
Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail

Schema Quality & AI Usability74

AI-judged instruction clarity (excellent).Pass
Context-footprint check failed: tool/resource definitions use about 1017 tokens (~127/item across 8 items; 8 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 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.
