This guide covers proven patterns for organizing FrontMCP projects at scale using the Nx monorepo structure.

​
Three-Layer Architecture

FrontMCP monorepos follow a three-layer architecture: 
my-platform/
├── apps/          # FrontMCP applications (business logic)
├── libs/          # Shared libraries (reusable code)
└── servers/       # Deployment shells (infrastructure)
LayerContainsDepends On
ServersEntry points, Docker/Vercel/Lambda configApps, Libs
AppsTools, resources, prompts, skills, agentsLibs
LibsShared utilities, plugins, adaptersOther Libs
Servers never contain business logic — they only compose apps. Apps never contain infrastructure config — they only define capabilities. Libs are reusable across both.

​
Multi-App Server Composition

Create different servers that compose different app combinations: 
# Create apps
nx g @frontmcp/nx:app crm
nx g @frontmcp/nx:app analytics
nx g @frontmcp/nx:app admin

# Create servers for different environments
nx g @frontmcp/nx:server production --apps crm,analytics --deploymentTarget node
nx g @frontmcp/nx:server staging --apps crm,analytics,admin --deploymentTarget node
nx g @frontmcp/nx:server edge --apps crm --deploymentTarget vercel

servers/
├── production/    # CRM + Analytics (Docker)
├── staging/       # CRM + Analytics + Admin (Docker)
└── edge/          # CRM only (Vercel)

​
Shared Libraries

​
Generic Libraries

Shared utilities used across multiple apps: 
nx g @frontmcp/nx:lib shared-utils
nx g @frontmcp/nx:lib data-models

​
Plugin Libraries

Reusable plugins published as npm packages: 
nx g @frontmcp/nx:lib audit-plugin --libType plugin --publishable --importPath @my-org/plugin-audit

​
Tool Register Libraries

Multi-tool packages shared across apps: 
nx g @frontmcp/nx:lib github-tools --libType tool-register

// In any app:
import { GithubToolsTools } from '@libs/github-tools';

@App({ id: 'crm', tools: [...GithubToolsTools, CreateLeadTool] })
class CrmApp {}

​
Dependency Graph

Visualize your workspace dependencies: 
nx graph
Nx tracks which projects depend on which, enabling:
  • Affected commands: nx affected -t test — only test projects affected by your changes
  • Build ordering: nx run-many -t build — builds in correct dependency order
  • Caching: Unchanged projects skip builds entirely

​
Tagging Convention

Use tags to enforce dependency rules: 
nx g @frontmcp/nx:app crm --tags "scope:crm,type:app"
nx g @frontmcp/nx:lib shared-utils --tags "scope:shared,type:lib"
nx g @frontmcp/nx:server production --tags "scope:infra,type:server"
Example boundary rules in .eslintrc.json: 
{
  "@nx/enforce-module-boundaries": [
    "error",
    {
      "depConstraints": [
        { "sourceTag": "type:app", "onlyDependOnLibsWithTags": ["type:lib"] },
        { "sourceTag": "type:server", "onlyDependOnLibsWithTags": ["type:app", "type:lib"] },
        { "sourceTag": "type:lib", "onlyDependOnLibsWithTags": ["type:lib"] }
      ]
    }
  ]
}

​
Per-Environment Servers

Create environment-specific servers with different configurations: 
servers/
├── dev/           # All apps, public auth, memory storage
├── staging/       # All apps, transparent auth, Redis
└── production/    # Selected apps, orchestrated auth, Redis cluster
Each server’s main.ts can customize providers and auth:
servers/production/src/main.ts
@FrontMcp({
  info: { name: 'Production', version: '1.0.0' },
  apps: [CrmApp, AnalyticsApp],
  auth: { mode: 'orchestrated', /* ... */ },
  providers: [RedisProvider],
})
export default class Server {}
