- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it
Traduit en clair un motif de rejet ou de refus de facture électronique (codes AFNOR XP Z12-012 : REJ_SEMAN, REJ_ADR, DEST_INC, NON_TRANSMISE, TX_TVA_ERR…) ou une règle de validation EN 16931 / française (BR-CO-15, BR-FR-10, BR-S-08…) : signification, action attendue, faut-il un avoir.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Ouvre une carte de dépôt dans la conversation. L'utilisateur y glisse sa facture électronique (PDF Factur-X, XML UBL ou CII, 15 Mo au maximum) ; le fichier est envoyé directement à MaFactureOK, analysé puis effacé, et la carte affiche le verdict (valide, à vérifier, invalide), chaque anomalie en français avec la correction attendue, et l'état des entreprises de la facture au registre officiel. À appeler dès que l'utilisateur veut vérifier, valider ou comprendre le rejet d'une facture qu'il possède en fichier. Aucun argument : le fichier n'est jamais transmis par le modèle.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Anlyon alternative

4 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
