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. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- 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. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability73
- AI-judged instruction clarity (excellent).Pass
- 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. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

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. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
create_link ~354
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | 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. |
No output schema declared.
No examples provided.
create_space ~75
Crée un espace client. Refusé avec le code `space_limit_reached` si la formule est pleine.
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | Nom affiché, par exemple « Maison Lartigue ». |
| slug | string | – | Raccourci dans les URL. Déduit du nom s'il est omis. |
No output schema declared.
No examples provided.
get_analytics ~210
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | Raccourci de l'espace client. |
No output schema declared.
No examples provided.
get_link ~53
Détaille un lien : sa destination FINALE (UTM comprises, telle que la reçoit le site d'arrivée) et ses clics sur 30 jours.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Identifiant du lien. |
No output schema declared.
No examples provided.
list_links ~108
Liste les liens. Un lien PARENT porte la destination ; un PLACEMENT (sublink) porte les UTM d'une publication précise et hérite du reste.
| Name | Type | Req | Description |
|---|---|---|---|
| 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. |
No output schema declared.
No examples provided.
list_spaces ~78
Liste les espaces du compte. Un espace = un client, une marque ou un projet ; tout le reste (liens, clics, ventes) vit dedans.
| Name | Type | Req | Description |
|---|---|---|---|
| cursor | string | – | Curseur renvoyé par l'appel précédent (`nextCursor`). |
| limit | integer | – | 1 à 100, 50 par défaut. |
No output schema declared.
No examples provided.
track_sale ~196
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.
| Name | Type | Req | Description |
|---|---|---|---|
| amount | integer | yes | 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. |
| 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 | yes | Votre numéro de facture — c'est lui qui garantit l'idempotence. |
| space | string | yes | Raccourci de l'espace client. |
No output schema declared.
No examples provided.
update_link ~261
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | 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`. |
No output schema declared.
