Cursor utilise le même schéma mcpServers que Claude Desktop. La config projet l'emporte sur la globale.

Cas d'usage

Usages concrets : prismatic-skills

Build a custom Prismatic connector for an internal API

👤 Integration engineers on teams using Prismatic ⏱ ~90 min advanced

Quand l'utiliser : You have an internal API that your Prismatic flows need to talk to.

Prérequis

Prismatic account + SDK — npm i -g @prismatic-io/prism; prism login
Skill installed — git clone https://github.com/prismatic-io/prismatic-skills ~/.claude/skills/prismatic-skills

Déroulement

Scaffold the connector

Use prismatic-skills. Scaffold a connector for our Orders API — base URL, bearer auth, actions for list, get, create.✓ Copié

→ Connector directory with TS entry points, manifest, test files
Implement actions

Fill in the listOrders action with pagination and error handling.✓ Copié

→ TS implementation with types and Prismatic input/output conventions
Test locally

Run the test harness with a mock response.✓ Copié

→ prism tests output; green

Résultat : A deployable connector with actions your flows can use.

Pièges

Missing input validation — Prismatic validates at the platform boundary; still use Zod or similar for runtime safety

Combiner avec : filesystem

Add a new action to an existing Prismatic connector

👤 Maintainers of deployed connectors ⏱ ~30 min intermediate

Quand l'utiliser : Business needs a new action (e.g., refund flow) on an existing integration.

Déroulement

Identify the pattern

Use prismatic-skills. Look at the existing actions/ and mimic the pattern for a new 'refundOrder' action.✓ Copié

→ Action file consistent with existing style
Publish

Bump the connector version and deploy.✓ Copié

→ prism integrations:publish succeeded

Résultat : Connector updated without breaking existing flows.

Pièges

Breaking input schema without version bump — Version the connector; old flows pin to old version until migrated

Combinaisons

Associez-le à d'autres MCPs pour un effet X10

prismatic-skill + filesystem

Manage a multi-connector monorepo

Add connectors/widgets-api/ following the same pattern as connectors/users-api/.✓ Copié

prismatic-skill + github

Review connector PRs with skill context

Review this PR against Prismatic connector conventions.✓ Copié

Outils

Ce que ce MCP expose

Outil	Entrées	Quand appeler	Coût
scaffold_connector	name, auth type, actions	New connector	0
write_action	action spec	Per-action implementation	0
run_tests	connector path	Before publish	local
publish_connector	connector path	Deploy	Prismatic deploy

Coût et limites

Coût d'exécution

Quota d'API: None in skill
Tokens par appel: Moderate
Monétaire: Prismatic plan applies; skill is free
Astuce: Test locally with the SDK before pushing to reduce deploy churn.

Sécurité

Permissions, secrets, portée

Stockage des identifiants : Prismatic credentials via prism CLI (not stored in skill)

Sortie de données : Prismatic platform + whatever APIs your connectors talk to

Connector code runs on the Prismatic platform — don't embed secrets; use Prismatic's credential store.

Dépannage

Erreurs courantes et correctifs

prism login fails

Token scope or expiry; re-login via browser flow

Vérifier : prism me

Connector publishes but flows can't see new action

Customers may need to upgrade connector version in their flow settings

Input schema rejected

Prismatic enforces specific input shapes; consult their docs or the skill's action templates

Alternatives

prismatic-skills vs autres

Alternative	Quand l'utiliser	Compromis
Prismatic low-code UI	Simple integrations, no custom code needed	Less flexibility; not versioned in git
Raw Prismatic SDK without skill	You already know the SDK well	Less guided scaffolding
