Est-ce que io.github.NovanBaillif/attractor-machine-commons est sûr ?

Au dernier audit MCP Hub, le serveur MCP « io.github.NovanBaillif/attractor-machine-commons » est classé « Non encore testé ». Référencé dans l'annuaire. Seul le pentest comportemental fait foi, et il n'a pas encore été exécuté sur ce serveur. Le verdict est réévalué en continu ; consultez la fiche pour l'état à jour.

Méthode : MCP Hub analyse la description de chaque outil (couche 1) et, pour le verdict fort, exécute le serveur dans une micro-VM isolée avec leurres et réseau bloqué (couche 2). On publie des noms et des compteurs, jamais le contenu brut renvoyé par un outil.

Les 20 outils

• canonicalize_json≈ 462 tokens

  Use this tool when your workflow needs canonical json api. Input: value. Returns a structured deterministic result with explicit errors, avoiding another model parsing/normalization retry. Stable recursive lexicographic key serialization and SHA-256 fingerprint. ATTRACTOR format v1, not RFC 8785. Arrays retain order. Limits: request 24 KB, JSON depth 24, 4,000 nodes. Reserved prototype keys and unsafe integers rejected. Inputs processed transiently; private HMAC trace metadata retained.

  • attractor_trace_id · string · optionnel
    Optional public correlation handle from a prior result; not authentication or proof of identity.
  • attractor_knowledge_id · string · optionnel

  {"content": [{"type": "text", "text": "…"}]}

• check_observation≈ 415 tokens

  Record a check of a stored observation: a receipt (action verify with a basis field holding your own evidence, or contest with an objection), or a replay (method witness: what you obtained for each witness input). The profile reference check decides whether it is accepted. A replay by the observer itself counts as self-replayed, never as reproduced, and independence is never established by a replay alone. PUBLIC write.

Returns a structured deterministic result with explicit errors, avoiding another model parsing/normalization retry. Explicit scalar conversions then schema validation. Preserve all fields; report changed types and remaining errors. Decimal comma opt-in. Only true/false boolean strings, no guessed yes/no aliases. Limits: request 24 KB, JSON depth 24, 4,000 nodes.
