## 🚀 Deployment Status

### Example Deployment

- **Environment**: Production
- **URL**: `https://specification-mcp-auth0.<your-subdomain>.workers.dev/mcp`
- **Transport**: HTTP Streamable
- **Database**: `specifications-prod`
- **Auth0 Domain**: `YOUR_TENANT.auth0.com`
- **OAuth Flow**: PKCE with state protection

## 📊 Usage

### Authentication Flow

1. User accesses MCP tool → Redirected to Auth0 consent screen
2. User approves permissions → Auth0 redirects with authorization code
3. Server exchanges code for JWT tokens → User can access tools

### Example Usage

```bash
# Create a specification
curl -X POST https://specification-mcp-auth0.<your-subdomain>.workers.dev/mcp \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -d '{
    "jsonrpc": "2.0",
    "method": "create_specification",
    "params": {
      "title": "API Specification",
      "content": "# API Spec\n\nThis is an API specification.",
      "version": "1.0.0",
      "tags": ["api", "backend"]
    },
    "id": "1"
  }'

# List specifications
curl -X POST https://specification-mcp-auth0.<your-subdomain>.workers.dev/mcp \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -d '{
    "jsonrpc": "2.0",
    "method": "list_specifications",
    "params": {"limit": 10},
    "id": "2"
  }'
```
