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 Security37
  • Malware scan not yet available for this package.Unverified
  • 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

Provenance & Transparency45
Schema Quality & AI Usability79
  • 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 6682 tokens (~131/item across 51 items; 51 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 Management23
  • Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass

The dependency tree was only partially resolved, so these counts may be incomplete.

MCP tools — 51 exposed · ~6,682 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.

Tool Tokens
xss_reflected_test ~123

Test multiple reflected XSS vectors against a parameter. Sends 10 payloads (script tags, event handlers, SVG, attribute injection, case variation, template literals) and checks if they appear unescaped in the response. Returns results array with reflected/encoded/status per payload, and vulnerable_count. Side effects: Read-only GET requests. Sends 10 requests.
