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 Security89
  • No malware found by supply-chain analysis.Pass
  • CVE check failed: a known high-severity CVE affects uuid 8.3.2, reached via @solana/web3.js > jayson > uuid. A fixed version is available. View diagnostics → Fail
  • No install/post-install scripts declared.Pass
  • 50 of 149 dependencies flagged as unhealthy (2 deprecated). View diagnostics → Partial
Provenance & Transparency45
Schema Quality & AI Usability79
  • AI-judged instruction clarity (excellent).Pass
  • Tool/resource definitions use about 746 tokens (~93/item across 8 items; 8 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management83
  • Stability observed for 25 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

MCP tools · 8 exposed · ~746 tokens

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 →
