## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 8 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 73/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1335 tokens (~166/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

## MCP tools (8)

### `list_spaces` (~78 tokens)

Liste les espaces du compte. Un espace = un client, une marque ou un projet ; tout le reste (liens, clics, ventes) vit dedans.

Input parameters:

- `cursor` (string): Curseur renvoyé par l'appel précédent (`nextCursor`).
- `limit` (integer): 1 à 100, 50 par défaut.

### `create_space` (~75 tokens)

Crée un espace client. Refusé avec le code `space_limit_reached` si la formule est pleine.

Input parameters:

- `name` (string, required): Nom affiché, par exemple « Maison Lartigue ».
- `slug` (string): Raccourci dans les URL. Déduit du nom s'il est omis.

### `list_links` (~108 tokens)

Liste les liens. Un lien PARENT porte la destination ; un PLACEMENT (sublink) porte les UTM d'une publication précise et hérite du reste.

Input parameters:

- `cursor` (string): Curseur de la page suivante.
- `limit` (integer): 1 à 100.
- `space` (string): Raccourci de l'espace. Omis = tous les espaces du compte.
- `status` (string): active (défaut), archived, ou all.

### `create_link` (~354 tokens)

Crée un lien court. Sans `parentId`, c'est un lien parent et `destination` est obligatoire. Avec `parentId`, c'est un placement : il hérite de la destination du parent et porte ses propres UTM. Renvoie `shortUrl`, prêt à publier.

Input parameters:

- `destination` (string): URL d'arrivée. Obligatoire pour un parent, interdite pour un placement.
- `domain` (string): Adresse qui porte le lien (« liens.votresite.fr »). Omise = le même choix que l'écran de création : le domaine de marque réservé à l'espace, sinon l'unique domaine de marque du compte, sinon l'adress…
- `label` (string): Nom du placement, par exemple « Pub Meta — mars ».
- `parentId` (string): Identifiant du lien parent, pour créer un placement.
- `slug` (string): Raccourci souhaité. Tiré au sort s'il est omis.
- `space` (string, required): Raccourci de l'espace client.
- `utmCampaign` (string): utm_campaign du placement.
- `utmContent` (string): utm_content du placement.
- `utmMedium` (string): utm_medium du placement.
- `utmSource` (string): utm_source du placement.
- `utmTerm` (string): utm_term du placement.

### `get_link` (~53 tokens)

Détaille un lien : sa destination FINALE (UTM comprises, telle que la reçoit le site d'arrivée) et ses clics sur 30 jours.

Input parameters:

- `id` (string, required): Identifiant du lien.

### `update_link` (~261 tokens)

Modifie la destination, le libellé ou l'ADRESSE d'un lien (`domain` et/ou `slug`), ou l'archive. Changer d'adresse ne casse rien : l'ancienne adresse continue de rediriger vers le même endroit et ses clics comptent sur ce lien (`previousShortUrls`) ; les placements qui partageaient son domaine le suivent. Un lien n'est JAMAIS supprimé : archivé, il cesse de rediriger (anciennes adresses comprises) mais son historique reste.

Input parameters:

- `archived` (boolean): true pour archiver, false pour réactiver.
- `destination` (string): Nouvelle URL d'arrivée (liens parents seulement).
- `domain` (string): Nouveau domaine de l'adresse (« liens.votresite.fr »), vérifié dans le compte et libre pour l'espace du lien ; « sbtq.link » pour revenir au domaine partagé. L'ancienne adresse continue de marcher.
- `id` (string, required): Identifiant du lien.
- `label` (string): Nouveau libellé.
- `slug` (string): Nouveau raccourci. Pris sur le domaine visé : erreur `slug_taken`, avec un raccourci libre proposé dans `details.suggestion`.

### `get_analytics` (~210 tokens)

Les chiffres d'un espace : clics, prospects, ventes, revenu ATTRIBUÉ et revenu NON attribué, plus le détail placement par placement. Montants en CENTIMES. Subtraq ne convertit pas les devises : si `mixedCurrencies` est vrai, les totaux ne concernent que `currency`. `model` choisit la lecture de l'attribution ; la réponse rappelle toujours lequel a servi.

Input parameters:

- `model` (string): Modèle d'attribution : `first` (premier clic, défaut et référence du produit), `last` (dernier clic avant la conversion) ou `linear` (partage entre tous les placements cliqués, revenu réparti au cent…
- `period` (string): 7d, 30d (défaut), 90d ou all.
- `space` (string, required): Raccourci de l'espace client.

### `track_sale` (~196 tokens)

Enregistre une VENTE et la rattache au placement d'origine de la personne. Montant en CENTIMES. `invoiceId` rend l'appel idempotent : le rejouer ne facture jamais deux fois. Une vente ne peut PAS être envoyée depuis un navigateur.

Input parameters:

- `amount` (integer, required): Montant en CENTIMES. 43 € s'écrit 4300.
- `clickId` (string): Identifiant de clic, si vous l'avez conservé.
- `currency` (string): Code à trois lettres. USD par défaut.
- `email` (string): Email de la personne — le plus simple pour la retrouver.
- `externalId` (string): Son identifiant dans votre système, si vous en avez un.
- `invoiceId` (string, required): Votre numéro de facture — c'est lui qui garantit l'idempotence.
- `space` (string, required): Raccourci de l'espace client.
