Prerequisites

Node.js 22+
Supabase account (free tier works)
Stripe account (test mode)

1. Clone & Install

git clone https://github.com/intelliforge-ai/skillstore
cd skillstore

# Web app
cd web && npm install

# MCP server
cd ../mcp-server && npm install

2. Configure Environment

cd web
cp .env.example .env.local
# Fill in your values (see Supabase + Stripe setup below)

3. Run Development Servers

# Terminal 1: Web app
cd web && npm run dev
# → http://localhost:3000

# Terminal 2: MCP server (for local testing)
cd mcp-server && SKILLSTORE_API_URL=http://localhost:3000/api SKILLSTORE_API_KEY=your_key npm run dev

Supabase Setup

Create a new Supabase project at https://supabase.com

Run the schema:

# In Supabase SQL editor, paste contents of:
supabase/schema.sql

Enable GitHub OAuth:
- Supabase Dashboard → Authentication → Providers → GitHub
- Create a GitHub OAuth App at https://github.com/settings/developers
- Callback URL: https://YOUR_PROJECT.supabase.co/auth/v1/callback

Copy credentials to .env.local:

NEXT_PUBLIC_SUPABASE_URL=https://xxx.supabase.co
NEXT_PUBLIC_SUPABASE_ANON_KEY=eyJxxx...
SUPABASE_SERVICE_ROLE_KEY=eyJxxx...

Stripe Setup

Create a Stripe account at https://stripe.com

Create products and prices:

Product: SkillStore Pro
Price: $12.00/month (recurring)
→ Copy the Price ID: price_xxx

Product: SkillStore Enterprise
Price: $49.00/month (recurring)
→ Copy the Price ID: price_xxx

Set up webhook:
- Stripe Dashboard → Developers → Webhooks → Add endpoint
- URL: https://skillstore.intelliforge.tech/api/stripe/webhook

STRIPE_SECRET_KEY=sk_live_xxx
STRIPE_WEBHOOK_SECRET=whsec_xxx
STRIPE_PRO_PRICE_ID=price_xxx
STRIPE_ENTERPRISE_PRICE_ID=price_xxx

For local testing with Stripe CLI:

stripe listen --forward-to localhost:3000/api/stripe/webhook

Fly.io Deployment (MCP Server)

cd mcp-server

# Install Fly CLI
curl -L https://fly.io/install.sh | sh

# Authenticate
fly auth login

# Create the app (first time only)
fly launch --name skillstore-mcp --region sin

# Set secrets
fly secrets set \
  SKILLSTORE_API_URL=https://skillstore.intelliforge.tech/api \
  NODE_ENV=production

# Deploy
fly deploy

# Check status
fly status
fly logs

The MCP server is a stdio-based process — it starts on demand via npx skillstore-mcp on the developer's machine. The Fly.io deployment is for the HTTP-based MCP transport (optional, for enterprise custom endpoints).

Vercel Deployment (Web App)

cd web

# Install Vercel CLI
npm i -g vercel

# Deploy (first time: follow prompts)
vercel

# Deploy to production
