Documentation Overview

@mostajs/net — Octonet

One schema, 11 transports, 13 databases, multi-tenant auth — out of the box. Schema-driven multi-protocol API server for the @mostajs ecosystem. Built with TypeScript on Fastify, designed for polyglot consumption (14 native NetClients).

Author : Dr Hamid MADANI <drmdh@msn.com> Homepage : octonet.amia.fr · mcp.amia.fr

Octonet stack as electrical sockets: @mostajs/orm plugs into 13 databases, @mostajs/net (Octonet) re-exposes them over 11 transports, Data-Plug bridges them, and NetClient fans out to 18 language clients consumed by any external app.

The socket board. @mostajs/orm connects to 13 databases; Octonet (@mostajs/net) re-exposes the same entities over 11 transports (REST, WebSocket, gRPC, MQTT, AMQP…); NetClient then fans out to 18 language clients — so any external app plugs into your data, in any runtime.

What is Octonet

Octonet (@mostajs/net) is a Node.js multi-transport server that exposes a single @mostajs/orm schema as 11 different network protocols simultaneously : REST, GraphQL, WebSocket, SSE, JSON-RPC, MCP, gRPC, tRPC, OData, NATS, Arrow Flight.

The same User entity is reachable as :

Terminal

curl https://octonet.amia.fr/api/v1/User              # REST
curl https://octonet.amia.fr/graphql -d '{"query":...}'  # GraphQL
wscat -c wss://octonet.amia.fr/ws                     # WebSocket
curl -N https://octonet.amia.fr/mcp                   # MCP (Claude Desktop)
# … 7 more

Backed by @mostajs/orm (13 SGBD dialects). Backed by @mostajs/rbac + @mostajs/auth + @mostajs/api-keys for multi-tenant identity. Backed by @mostajs/mproject for multi-project routing.

Octonet is the second cerebral lobe of the @mostajs trilogy :

#1 — @mostajs/orm : data persistence (13 databases)
#2 — Octonet : multi-protocol transport (11 wire protocols)
#3 — NetClients polyglottes : 14 native client libraries (Java, .NET, Python, Go, Swift, Kotlin, Dart, Rust, PHP, Ruby, Elixir, Lua, Delphi, Unity)

Try in 2 clicks (T1 sandbox)

The fastest way to test Octonet from any of the 14 runtimes :

Open https://octonet.amia.fr/try
Pick an alias (e.g. alice-42)
Get an apikey scoped to your sandbox

Terminal

curl -X POST https://octonet.amia.fr/try \
  -H "Content-Type: application/json" \
  -d '{"alias":"alice-42"}'

# Response:
{
  "status": "ok",
  "data": {
    "alias": "alice-42",
    "projectSlug": "sandbox-alice-42",
    "apiKey": "sk_test_…(64 chars, shown ONCE)",
    "permissions": { "projects":["sandbox-alice-42"], "operations":["read","write"], "transports":["rest","mcp"] },
    "expiresAt": "2026-05-02T18:38:19.920Z",
    "quota": { "reqPerDay": 500 },
    "exampleCurl": "curl https://octonet.amia.fr/api/v1/sandbox-alice-42/User -H \"X-API-Key: sk_test_…\"",
    "mcpUrl": "https://octonet.amia.fr/mcp"
  }
}

Your sandbox is :

A private SQLite file (isolated from other aliases)
Pre-seeded with User, Product, Order entities
Read+write CRUD via REST and MCP
500 requests/day quota
TTL 7 days (auto-deleted if idle)
Free, no email required, anti-abuse rate-limited (10 sandboxes/h/IP)

Use the apikey in any of the 14 NetClients :

server.ts

# Java / .NET / Python / Go / etc.
export MOSTAJS_NET_URL=https://octonet.amia.fr
export MOSTAJS_NET_API_KEY=sk_test_…

3-tier onboarding model

Tier	Cible	Auth	Quota	Use case
T1 — Sandbox publique `/try`	"I want to test in 10 minutes"	alias seul (pas d'email)	500 req/jour, TTL 7j	démo NetClients, intégration tests
T2 — Compte enregistré octocloud.amia.fr	"j'utilise vraiment, gratuit"	email + mot de passe	10 000 req/jour	apps personnelles, side-projects
T3 — Self-host `npx @mostajs/net init`	"tes données chez toi"	admin local	aucune	enterprise, on-premise, AGPL

11 transports

Auto-generated from your registered schemas. Toggle each via env var (default : all enabled).

#	Transport	Endpoint	Use case	Notes
1	REST	`/api/v1/{Entity}` · `/api/v1/{project}/{Entity}`	universel	15 routes par entité (CRUD + count + search + aggregate + bulk + relations)
2	GraphQL	`/graphql` (POST)	front-end riches	schéma + GraphiQL IDE auto-générés via mercurius
3	WebSocket	`wss://…/ws`	temps réel	events `entity.created/updated/deleted/upserted` broadcast
4	SSE	`/events` (GET stream)	mobile / browser-friendly	server-sent events
5	JSON-RPC	`/rpc` (POST)	EVM-adjacent, classic	JSON-RPC 2.0 + method discovery
6	MCP	`/mcp` (POST/GET SSE)	agents IA (Claude, ChatGPT)	15 tools/entité auto-générés (listed on mcp.so)
7	gRPC	`:50051`	inter-services low-latency	`.proto` auto-généré, 6 RPCs/entité
8	tRPC	`/trpc/{Entity}.{op}`	TypeScript fullstack	type generation côté client
9	OData	`/odata/{Collection}` (+ `$metadata`)	SAP/Microsoft Dynamics	OData v4 ($filter, $select, $orderby)
10	NATS	`mostajs.{Entity}.{op}`	pub/sub edge	request-reply messaging
11	Arrow Flight	`/arrow/*`	analytics columnaire	streaming zero-copy

Le même schéma, 11 portes d'entrée différentes, 0 codegen.

13 databases

Persistence dialects fournis par @mostajs/orm :

Catégorie	Bases	Dialect ID
SQL mainstream	PostgreSQL, MySQL, MariaDB, SQLite	`postgres`, `mysql`, `mariadb`, `sqlite`
SQL enterprise	Oracle, SQL Server, DB2, SAP HANA, HSQLDB, Sybase	`oracle`, `mssql`, `db2`, `hana`, `hsqldb`, `sybase`
NewSQL / Cloud	CockroachDB, Google Cloud Spanner	`cockroachdb`, `spanner`
NoSQL	MongoDB	`mongodb`

Switch dialect = changer 1 ligne d'env :

bash

DB_DIALECT=postgres → DB_DIALECT=mongodb
SGBD_URI=postgresql://… → SGBD_URI=mongodb://…

Multi-tenant authentication

Octonet utilise un middleware d'authentification basé sur API keys avec scopes (orienté machine-to-machine) + RBAC pour la gestion humaine. L'orchestrateur agnostique vit dans @mostajs/auth/lib/check-request.ts.

Flux d'auth d'une requête

Code

HTTP Request
  │
  ▼
authGuard (Fastify adapter)
  │
  ▼
checkRequest (@mostajs/auth — framework-agnostic)
  │
  ├─ extract X-API-Key from header / Bearer token / ?apikey=
  ├─ resolveApiKey (@mostajs/api-keys) — DB lookup + bcrypt verify
  ├─ isScopeAuthorized (@mostajs/api-keys) — check scope.values
  │     for each (scope, value) pair :
  │       checks: [{scope:'projects', value:slug},
  │                {scope:'operations', value:'read'|'write'|'admin'},
  │                {scope:'transports', value:'rest'|'mcp'|...}]
  ├─ touchApiKey — fire-and-forget : lastUsedAt, usageCount, lastIp
  │
  ▼
ormHandler (entité CRUD) ─→ sanitizer (strip password/hash/tokens)
  │
  ▼
HTTP Response

Scope-based permissions (generic, extensible)

Une apikey a la shape :

JSON Config

{
  permissions: {
    scopes: {
      projects:   ['my-project','demo'] | '*',     // declared by @mostajs/mproject
      operations: ['read','write','admin'] | '*',  // declared by @mostajs/orm
      transports: ['rest','graphql','mcp'] | '*',  // declared by @mostajs/net
      // anything: any module can register a new scope
    },
    rateLimit: 500,
  }
}

@mostajs/api-keys ne connaît PAS les noms projects/operations/transports — c'est volontaire. Chaque module enregistre ses scopes au boot via registerScope(dialect, {name, label, …}). Le check est générique : isScopeAuthorized(perms, scope, value).

HTTP status mapping

Cas	HTTP code	Body
Pas d'apikey	401	`{error: {code:'UNAUTHORIZED', message:'API key required…'}}`
Apikey invalide / révoquée	401	`{error: {code:'UNAUTHORIZED', message:'Invalid or revoked API key'}}`
Apikey valide hors scope	403	`{error: {code:'FORBIDDEN', message:'API key not authorized for X="Y"'}}`
Apikey OK	200/201	`{status:'ok', data: …}` (sanitized — no password/hash)

MCP fallback (compat mcp.so)

L'endpoint /mcp autorise un fallback automatique sur l'apikey labelée public-default quand aucune clé n'est présentée — préserve la compat avec mcp.so / Claude Desktop. La clé publique est read-only sur le projet default uniquement → écritures bloquées.

Sanitizer

Les champs password, hash, verifyToken, resetToken, apiKeyHash, secret, privateKey sont automatiquement strippés de toutes les réponses JSON par un middleware global. Aucun risque de leak à travers /api/v1/User?limit=1.

Generic scope registry

Le catalogue des scopes vit en base de données du projet accueillant (pas de fichier JSON, pas de constantes hardcodées) :

sql

-- Auto-créées au boot via @mostajs/api-keys
CREATE TABLE api_key_scopes (
  id, name, label, description, icon, cardinality,
  valuesSource ('static' | 'dynamic'), dynamicSourceRef
);

CREATE TABLE api_key_scope_values (
  id, scopeName, value, label, sortOrder, metadata
);

Chaque module enregistre ses scopes au boot :

server.ts

import { registerScope } from '@mostajs/api-keys/server'

// Dans mosta-net/src/server.ts (boot)
await registerScope(dialect, {
  name: 'transports', label: 'Network transports',
  cardinality: 'low', valuesSource: 'static',
  staticValues: [
    {value:'rest', sortOrder:1},
    {value:'graphql', sortOrder:2},
    // … 9 more
  ],
})

await registerScope(dialect, {
  name: 'projects', label: 'Projects',
  cardinality: 'high', valuesSource: 'dynamic',
  dynamicSourceRef: 'Project.slug',  // queried at runtime
})

L'admin UI charge le catalogue dynamique via GET /api/api-keys/scopes et rend une matrice (composant React ApiKeyScopeMatrix dans @mostajs/api-keys/components/).

Multi-project support

Via @mostajs/mproject — N bases de données isolées sur le même serveur.

System dialect (séparé du singleton métier)

Disponible depuis v2.7.5 — résout le bug « apikeys introuvables après /api/change-dialect » observé en prod.

Pourquoi deux dialects distincts ?

Octonet expose des routes admin qui mutent la connexion DB au runtime (/api/change-dialect, /api/reload-config, /api/reconnect) — légitime côté métier (les entités userland du projet courant peuvent migrer postgres → sqlite → mongodb selon les besoins de l'admin).

Mais les modules système (apikeys, RBAC users, audit, plans de souscription, payments, project-life metadata) doivent vivre dans une base stable qui ne suit pas ces mutations. Sinon : un changement de dialect métier rend les apikeys introuvables, l'admin se trouve verrouillé hors de l'IHM.

Rôle	Variable env	Mutable au runtime ?	Lu par
Métier (entités userland)	`DB_DIALECT` + `SGBD_URI`	Oui (IHM admin)	`EntityService`, transports, routes data
Système (infra Octonet)	`MOSTA_SYSTEM_DIALECT` + `MOSTA_SYSTEM_URI`	Non (stable)	RBAC, apikey-middleware, account-scope, auth guards, sandbox /try

Configuration recommandée (prod multi-base)

bash

# Métier — peut bouger via /api/change-dialect
DB_DIALECT=postgres
SGBD_URI=postgresql://hmd:***@127.0.0.1:5432/octonet_business

# Système — stable, jamais touché par les routes admin
MOSTA_SYSTEM_DIALECT=postgres
MOSTA_SYSTEM_URI=postgresql://hmd:***@127.0.0.1:5432/octonet_system

Configuration mono-base (dev / déploiement simple)

Laisser MOSTA_SYSTEM_* vides → alias automatique vers le singleton métier (rétro-compat 100 %, comportement identique au pré-v2.7.5).

How-to

1. Migrer un déploiement existant vers le mode multi-base

server.ts

# 1. Sauvegarder la base actuelle
pg_dump octonet_business > backup-pre-split.sql

# 2. Créer la base système (vide — RBAC seed re-exécute au boot)
createdb octonet_system

# 3. Ajouter MOSTA_SYSTEM_* dans .env
echo 'MOSTA_SYSTEM_DIALECT=postgres' >> .env.local
echo 'MOSTA_SYSTEM_URI=postgresql://hmd:***@127.0.0.1:5432/octonet_system' >> .env.local

# 4. Restart Octonet — le bootstrap RBAC + scopes seed sur octonet_system
pm2 restart octonet-mcp

# 5. Restaurer les apikeys et RBAC users de l'ancienne base
#    (à scripter selon convention métier — typiquement export/import des
#    tables api_keys, users, roles, permissions, scopes, scope_values)

2. Vérifier que le système est bien isolé du métier

bash

# Avant /api/change-dialect : apikey doit fonctionner
curl -H "X-API-Key: sk_live_…" http://localhost:4488/api/auth/verify
# → 200 OK

# Bouger le dialect métier vers SQLite
curl -X POST -H "Content-Type: application/json" \
  -d '{"dialect":"sqlite","uri":":memory:","connect":true}' \
  http://localhost:4488/api/change-dialect
# → "Dialecte changé et connecté : sqlite"

# Re-tester l'apikey — DOIT toujours fonctionner (système intact)
curl -H "X-API-Key: sk_live_…" http://localhost:4488/api/auth/verify
# → 200 OK (bug résolu en v2.7.5)

Avant v2.7.5, le 2ᵉ curl retournait 503 metadata DB unavailable ou 401 PostgreSQL not connected. Call connect() first.

3. Lire le system dialect depuis du code applicatif

server.ts

import { getSystemDialect } from '@mostajs/data-plug'

const sysDialect = await getSystemDialect()
// Utiliser comme un dialect normal pour requêter les tables système
// (apikeys, users, roles, audit_log, plans, etc.)

4. Inspecter le bootstrap au démarrage

Au boot d'octonet-mcp, deux logs apparaissent :

Code

✓ DB connectée: postgres                            ← métier
✓ System dialect: postgres (octonet_system)         ← système (si MOSTA_SYSTEM_* défini)
✓ RBAC ready — admin=… trial=… public=…             ← seed côté système
✓ ApiKey middleware on REST/SSE/GraphQL/...         ← câblé sur système

Sites système dans `src/server.ts` (pour référence)

18 callers tirent désormais leur dialect via getSystemDialect() au lieu du singleton métier :

Bloc	Sites	Caller
RBAC bootstrap	1	`bootstrapRbac(systemDialect, …)`
Scopes register	4	`registerScope(systemDialect, …)` × 3 + `systemDialect.initSchema(scopeTables)`
Middlewares globaux	2	`createApiKeyMiddleware(() => systemDialect, …)` + `createAccountScopeMiddleware(() => systemDialect)`
Middlewares per-transport	2	idem appliqués sur chaque `transport.use(…)`
Auth guards transports	6	`authGuard(systemDialect, …)` × 6 (SSE, GraphQL, JSON-RPC, gRPC, tRPC, OData)
Custom `/api/auth/verify`	2	`checkApiKey(systemDialect, …)` + `new UserRepository(systemDialect)`
Sandbox `/try`	2	`registerTryRoutes({ dialect: systemDialect, … })` + `startTrialCleanupJob({ dialect: systemDialect, … })`

Le dialect métier (dialect) reste utilisé légitimement pour :

Bootstrap initial du singleton métier (L98) + pm.setDefault('default', dialect, …) (L126, L240)
Routes admin /api/reconnect, /api/change-dialect, /api/reload-config, /api/test-connection, /api/truncate-tables, /api/drop-tables — toutes opérations explicitement métier
EntityService qui sert les entités userland (opérations CRUD via les transports protégés)

Boot sequence

Load .env via @mostajs/config (profile cascade MOSTA_ENV)
Connect main dialect (SGBD_URI)
Load schemas (priority : getAllSchemas() registry → schemas.json → SCHEMAS_PATH directory scan)
dialect.initSchema(schemas) with strategy update/create
Bootstrap RBAC (octonet-rbac-bootstrap.ts) :
- register UserSchema/RoleSchema/PermissionSchema/PermissionCategorySchema/AccountSchema/ApiKeySchema
- seedRBAC(OCTONET_RBAC_SEED) — 6 categories, 25 permissions, 4 roles (admin/subscriber/trial/public)
- createAdmin() from OCTONET_ADMIN_EMAIL/PASSWORD
- create Account trial-playground (type='trial')
- create User public-demo (role=public)
- create Account public-system (type='system')
- generate ApiKey public-default scoped to default project (read-only, REST + MCP) — emitted ONCE in clear
Register canonical scopes : projects (dynamic, Project.slug), operations (static : read/write/admin), transports (static : 11 values)
Push default project to projects-tree.json (ownerId=admin, visibility=public)
Load additional projects from projects-tree.json
Wrap ormHandler with composeMiddleware([sanitizer, apikey], ormHandler) → protectedOrmHandler
Start each enabled transport :
- transport.use(loggingMiddleware)
- transport.use(sanitizerMiddleware)
- transport.use(apiKeyMiddleware)
- transport.setHandler(ormHandler)
- transport.start(config)
Register Fastify routes :
- registerDynamicRestRoutes(app, protectedOrmHandler, pm) — /api/v1/...
- registerProjectRoutes(app, pm, protectedOrmHandler) — /:project/*
- registerTryRoutes(app, {dialect, pm}) — /try POST
- registerTryPage(app) — /try GET (HTML)
- startTrialCleanupJob({dialect, pm}) — cron horaire TTL 7j
Listen on port (MOSTA_NET_PORT)

Documentation Overview

@mostajs/net — Octonet

One schema, 11 transports, 13 databases, multi-tenant auth — out of the box. Schema-driven multi-protocol API server for the @mostajs ecosystem. Built with TypeScript on Fastify, designed for polyglot consumption (14 native NetClients).

Author : Dr Hamid MADANI <drmdh@msn.com> Homepage : octonet.amia.fr · mcp.amia.fr

The socket board. @mostajs/orm connects to 13 databases; Octonet (@mostajs/net) re-exposes the same entities over 11 transports (REST, WebSocket, gRPC, MQTT, AMQP…); NetClient then fans out to 18 language clients — so any external app plugs into your data, in any runtime.

What is Octonet

The same User entity is reachable as :

Terminal

curl https://octonet.amia.fr/api/v1/User              # REST
curl https://octonet.amia.fr/graphql -d '{"query":...}'  # GraphQL
wscat -c wss://octonet.amia.fr/ws                     # WebSocket
curl -N https://octonet.amia.fr/mcp                   # MCP (Claude Desktop)
# … 7 more

Backed by @mostajs/orm (13 SGBD dialects). Backed by @mostajs/rbac + @mostajs/auth + @mostajs/api-keys for multi-tenant identity. Backed by @mostajs/mproject for multi-project routing.

Octonet is the second cerebral lobe of the @mostajs trilogy :

#1 — @mostajs/orm : data persistence (13 databases)
#2 — Octonet : multi-protocol transport (11 wire protocols)
#3 — NetClients polyglottes : 14 native client libraries (Java, .NET, Python, Go, Swift, Kotlin, Dart, Rust, PHP, Ruby, Elixir, Lua, Delphi, Unity)

Try in 2 clicks (T1 sandbox)

The fastest way to test Octonet from any of the 14 runtimes :

Open https://octonet.amia.fr/try
Pick an alias (e.g. alice-42)
Get an apikey scoped to your sandbox

Terminal

curl -X POST https://octonet.amia.fr/try \
  -H "Content-Type: application/json" \
  -d '{"alias":"alice-42"}'

# Response:
{
  "status": "ok",
  "data": {
    "alias": "alice-42",
    "projectSlug": "sandbox-alice-42",
    "apiKey": "sk_test_…(64 chars, shown ONCE)",
    "permissions": { "projects":["sandbox-alice-42"], "operations":["read","write"], "transports":["rest","mcp"] },
    "expiresAt": "2026-05-02T18:38:19.920Z",
    "quota": { "reqPerDay": 500 },
    "exampleCurl": "curl https://octonet.amia.fr/api/v1/sandbox-alice-42/User -H \"X-API-Key: sk_test_…\"",
    "mcpUrl": "https://octonet.amia.fr/mcp"
  }
}

Your sandbox is :

A private SQLite file (isolated from other aliases)
Pre-seeded with User, Product, Order entities
Read+write CRUD via REST and MCP
500 requests/day quota
TTL 7 days (auto-deleted if idle)
Free, no email required, anti-abuse rate-limited (10 sandboxes/h/IP)

Use the apikey in any of the 14 NetClients :

server.ts

# Java / .NET / Python / Go / etc.
export MOSTAJS_NET_URL=https://octonet.amia.fr
export MOSTAJS_NET_API_KEY=sk_test_…

Le même schéma, 11 portes d'entrée différentes, 0 codegen.

13 databases

Persistence dialects fournis par @mostajs/orm :

Catégorie	Bases	Dialect ID
SQL mainstream	PostgreSQL, MySQL, MariaDB, SQLite	`postgres`, `mysql`, `mariadb`, `sqlite`
SQL enterprise	Oracle, SQL Server, DB2, SAP HANA, HSQLDB, Sybase	`oracle`, `mssql`, `db2`, `hana`, `hsqldb`, `sybase`
NewSQL / Cloud	CockroachDB, Google Cloud Spanner	`cockroachdb`, `spanner`
NoSQL	MongoDB	`mongodb`

);

CREATE TABLE api_key_scope_values (
  id, scopeName, value, label, sortOrder, metadata
);

Chaque module enregistre ses scopes au boot :

server.ts

import { registerScope } from '@mostajs/api-keys/server'

// Dans mosta-net/src/server.ts (boot)
await registerScope(dialect, {
  name: 'transports', label: 'Network transports',
  cardinality: 'low', valuesSource: 'static',
  staticValues: [
    {value:'rest', sortOrder:1},
    {value:'graphql', sortOrder:2},
    // … 9 more
  ],
})

await registerScope(dialect, {
  name: 'projects', label: 'Projects',
  cardinality: 'high', valuesSource: 'dynamic',
  dynamicSourceRef: 'Project.slug',  // queried at runtime
})

L'admin UI charge le catalogue dynamique via GET /api/api-keys/scopes et rend une matrice (composant React ApiKeyScopeMatrix dans @mostajs/api-keys/components/).

Multi-project support

Via @mostajs/mproject — N bases de données isolées sur le même serveur.

System dialect (séparé du singleton métier)

Disponible depuis v2.7.5 — résout le bug « apikeys introuvables après /api/change-dialect » observé en prod.

Pourquoi deux dialects distincts ?

Rôle	Variable env	Mutable au runtime ?	Lu par
Métier (entités userland)	`DB_DIALECT` + `SGBD_URI`	Oui (IHM admin)	`EntityService`, transports, routes data
Système (infra Octonet)	`MOSTA_SYSTEM_DIALECT` + `MOSTA_SYSTEM_URI`	Non (stable)	RBAC, apikey-middleware, account-scope, auth guards, sandbox /try

Configuration recommandée (prod multi-base)

bash

# Métier — peut bouger via /api/change-dialect
DB_DIALECT=postgres
SGBD_URI=postgresql://hmd:***@127.0.0.1:5432/octonet_business

# Système — stable, jamais touché par les routes admin
MOSTA_SYSTEM_DIALECT=postgres
MOSTA_SYSTEM_URI=postgresql://hmd:***@127.0.0.1:5432/octonet_system

Configuration mono-base (dev / déploiement simple)

Laisser MOSTA_SYSTEM_* vides → alias automatique vers le singleton métier (rétro-compat 100 %, comportement identique au pré-v2.7.5).

How-to

1. Migrer un déploiement existant vers le mode multi-base

server.ts

# 1. Sauvegarder la base actuelle
pg_dump octonet_business > backup-pre-split.sql

# 2. Créer la base système (vide — RBAC seed re-exécute au boot)
createdb octonet_system

# 3. Ajouter MOSTA_SYSTEM_* dans .env
echo 'MOSTA_SYSTEM_DIALECT=postgres' >> .env.local
echo 'MOSTA_SYSTEM_URI=postgresql://hmd:***@127.0.0.1:5432/octonet_system' >> .env.local

# 4. Restart Octonet — le bootstrap RBAC + scopes seed sur octonet_system
pm2 restart octonet-mcp

# 5. Restaurer les apikeys et RBAC users de l'ancienne base
#    (à scripter selon convention métier — typiquement export/import des
#    tables api_keys, users, roles, permissions, scopes, scope_values)

2. Vérifier que le système est bien isolé du métier

bash

# Avant /api/change-dialect : apikey doit fonctionner
curl -H "X-API-Key: sk_live_…" http://localhost:4488/api/auth/verify
# → 200 OK

# Bouger le dialect métier vers SQLite
curl -X POST -H "Content-Type: application/json" \
  -d '{"dialect":"sqlite","uri":":memory:","connect":true}' \
  http://localhost:4488/api/change-dialect
# → "Dialecte changé et connecté : sqlite"

# Re-tester l'apikey — DOIT toujours fonctionner (système intact)
curl -H "X-API-Key: sk_live_…" http://localhost:4488/api/auth/verify
# → 200 OK (bug résolu en v2.7.5)

Avant v2.7.5, le 2ᵉ curl retournait 503 metadata DB unavailable ou 401 PostgreSQL not connected. Call connect() first.

3. Lire le system dialect depuis du code applicatif

server.ts

import { getSystemDialect } from '@mostajs/data-plug'

const sysDialect = await getSystemDialect()
// Utiliser comme un dialect normal pour requêter les tables système
// (apikeys, users, roles, audit_log, plans, etc.)

4. Inspecter le bootstrap au démarrage

Au boot d'octonet-mcp, deux logs apparaissent :

Code

✓ DB connectée: postgres                            ← métier
✓ System dialect: postgres (octonet_system)         ← système (si MOSTA_SYSTEM_* défini)
✓ RBAC ready — admin=… trial=… public=…             ← seed côté système
✓ ApiKey middleware on REST/SSE/GraphQL/...         ← câblé sur système

Sites système dans `src/server.ts` (pour référence)

18 callers tirent désormais leur dialect via getSystemDialect() au lieu du singleton métier :

Bloc	Sites	Caller
RBAC bootstrap	1	`bootstrapRbac(systemDialect, …)`
Scopes register	4	`registerScope(systemDialect, …)` × 3 + `systemDialect.initSchema(scopeTables)`
Middlewares globaux	2	`createApiKeyMiddleware(() => systemDialect, …)` + `createAccountScopeMiddleware(() => systemDialect)`
Middlewares per-transport	2	idem appliqués sur chaque `transport.use(…)`
Auth guards transports	6	`authGuard(systemDialect, …)` × 6 (SSE, GraphQL, JSON-RPC, gRPC, tRPC, OData)
Custom `/api/auth/verify`	2	`checkApiKey(systemDialect, …)` + `new UserRepository(systemDialect)`
Sandbox `/try`	2	`registerTryRoutes({ dialect: systemDialect, … })` + `startTrialCleanupJob({ dialect: systemDialect, … })`

Le dialect métier (dialect) reste utilisé légitimement pour :

Bootstrap initial du singleton métier (L98) + pm.setDefault('default', dialect, …) (L126, L240)
Routes admin /api/reconnect, /api/change-dialect, /api/reload-config, /api/test-connection, /api/truncate-tables, /api/drop-tables — toutes opérations explicitement métier
EntityService qui sert les entités userland (opérations CRUD via les transports protégés)

Boot sequence

Load .env via @mostajs/config (profile cascade MOSTA_ENV)
Connect main dialect (SGBD_URI)
Load schemas (priority : getAllSchemas() registry → schemas.json → SCHEMAS_PATH directory scan)
dialect.initSchema(schemas) with strategy update/create
Bootstrap RBAC (octonet-rbac-bootstrap.ts) :
- register UserSchema/RoleSchema/PermissionSchema/PermissionCategorySchema/AccountSchema/ApiKeySchema
- seedRBAC(OCTONET_RBAC_SEED) — 6 categories, 25 permissions, 4 roles (admin/subscriber/trial/public)
- createAdmin() from OCTONET_ADMIN_EMAIL/PASSWORD
- create Account trial-playground (type='trial')
- create User public-demo (role=public)
- create Account public-system (type='system')
- generate ApiKey public-default scoped to default project (read-only, REST + MCP) — emitted ONCE in clear
Register canonical scopes : projects (dynamic, Project.slug), operations (static : read/write/admin), transports (static : 11 values)
Push default project to projects-tree.json (ownerId=admin, visibility=public)
Load additional projects from projects-tree.json
Wrap ormHandler with composeMiddleware([sanitizer, apikey], ormHandler) → protectedOrmHandler
Start each enabled transport :
- transport.use(loggingMiddleware)
- transport.use(sanitizerMiddleware)
- transport.use(apiKeyMiddleware)
- transport.setHandler(ormHandler)
- transport.start(config)
Register Fastify routes :

14 polyglot NetClients

Octonet est consommable depuis 14 runtimes natifs, avec la même apikey, la même URL :

Runtime	Package	Registre
Node/TS	`@mostajs/net/client` (built-in)	npm
Java	`com.mostajs:mostajs-net-client`	Maven Central
Java + Spring Boot	`com.mostajs:mostajs-net-client-spring-boot-starter`	Maven Central
.NET	`MostaJs.Net.Client`	NuGet
Python	`mostajs-net-client`	PyPI
Go	`github.com/apolocine/mosta-net-client-go`	pkg.go.dev
Swift	`mosta-net-client-swift`	Swift Package Index
Kotlin	`io.github.apolocine:mostajs-net-client-kt`	Maven Central

Delphi	`MostaJsNetClient`	GetIt
Unity (C#)	`com.mostajs.net-client`	OpenUPM

Monorepo : github.com/apolocine/mosta-net-clients

Chaque NetClient suit le même contrat d'API :

Code

NetClient.create()
  .url(...)
  .apiKey(...)
  .build()
  .findAll(entity, filter, options)
  .findById(entity, id)
  .create(entity, data)
  .update(entity, id, data)
  .delete(entity, id)
  .uploadSchemasJson(schemas)
  .health()

Production deploy (amia.fr)

Le déploiement de référence tourne sur octonet.amia.fr + mcp.amia.fr (alias compat) en backend PostgreSQL :

URL	Rôle
`https://octonet.amia.fr`	Octonet server (REST, MCP, GraphQL, WS, SSE, tRPC, OData, JSON-RPC)
`https://mcp.amia.fr`	alias DNS de compatibilité — historique mcp.so
`https://octocloud.amia.fr`	Octocloud — portail SaaS Next.js (subscriptions, admin UI)

Le kit de déploiement complet est dans Entreprise/octonet-mcp/ :

apache/mcp.amia.fr.conf — vhost Apache2 (proxy SSE, WS upgrade, certs Let's Encrypt SAN)
ecosystem.config.cjs — config PM2
deploy.sh / install.sh / update.sh — scripts d'orchestration
tests/smoke-all.sh — suite de smoke tests (DNS, TLS, /health, SSE MCP, REST, /try, NetClient Java)

CLI

Terminal

npx mostajs-net serve                      # Start server
npx mostajs-net mcp                        # MCP-only mode
npx mostajs-net generate-apikey <label>    # Émettre une apikey via CLI
npx mostajs-net hash-password <password>   # Hash bcrypt
npx mostajs-net info                       # JSON config dump

npx octonet-mcp --dialect=X --uri=Y        # Standalone MCP server (process séparé)
