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 (95 of 99), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency45
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
  • Tool/resource definitions use about 626 tokens (~89/item across 7 items; 5 tools + 2 resources), lean.Pass
  • 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
  • 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

Changelog

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

  • 3 Aug 26 +1

    No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

MCP tools — 5 exposed · ~514 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
compare_models ~112

Side-by-side comparison of two models by display_name (case-insensitive substring). Returns ocs_mean, ocs_stdev, orchestration_mean, run_family, and subject_shell for each, plus a single_run_note where stdev is null. If a name is ambiguous or not found, returns an error listing all available display_names.

NameTypeReqDescription
model_astringyesDisplay name (or substring) of the first model
model_bstringyesDisplay name (or substring) of the second model

No output schema declared.

No examples provided.

get_case ~122

Return the full case for a given pair_id (axes 1/2/4) or id (axis 3): malign and benign task prompts, expected decisions, grounding rationale, and bypass patterns. Axis 3 cases are single (unmatched) and use an 'id' field instead of 'pair_id'. Use list_cases to browse available ids.

NameTypeReqDescription
axisstringyesThe axis this case belongs to
pair_idstringyesThe pair_id (axes 1/2/4) or id (axis 3) to retrieve

No output schema declared.

No examples provided.

get_methodology ~85

Return the benchmark design: the 4 axes, the OCS formula (Youden's J), the 5 decision labels (PROCEED, PROCEED_SANCTIONED, REFUSE, ESCALATE, REROUTE), scoring blocks, and a concise what-it-measures / what-it-doesn't summary. Sourced from the baked case-file metadata.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

get_results ~84

Return all model calibration profiles (OCS mean/stdev, orchestration mean, run_family, subject_shell), plus generated_at, included_lab_labels, and the not-a-flat-leaderboard caveat. Models are returned as-is — do not pre-sort into a naive leaderboard. Single-run models (null stdev) must not be ranked as-if reliable against multi-run models.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

list_cases ~111

Return case metadata (no full task prompts): pair_id/id, axis, tier, grounding, and side indicators (malign/benign for axes 1/2/4; null for axis 3). Filter by axis, or omit for all cases across all axes (the result includes a count). Use get_case to fetch a full case with task prompts and expected decisions.
