🚀 What's New in v0.3.0

🤖 AI Schema System - Game Changing!

• ⚡ Proactive Behavior: AI automatically searches memory before responding
• 🔇 Silent Operations: Background AI operations with silent: true
• 🎯 Entity Detection: Auto-detects "UserService", "PaymentManager" → searches instantly
• 📋 Command Recognition: "implement auth" → auto-searches patterns + creates tasks
• 🔗 AI Mode Access: help({ ai_mode: true }) reveals complete AI capabilities

📁 Project Isolation & Smart Config

• Isolated Memory: Each project gets its own database context
• Configuration Files: nova-memory.config.js for project-specific settings
• Instant Switching: Seamlessly move between project contexts
• Smart Versioning: Entity evolution tracking with duplicate prevention
• 4 Search Modes: Smart, Precise, Fast, Balanced for optimal performance

🔄 Version Tracking & Evolution

• Entity Versioning: Track how your code entities evolve over time
• Duplicate Prevention: Smart detection prevents redundant storage
• Version History: memory({ action: "versions", entity_name: "X" }) shows evolution
• Relationship Evolution: See how connections between entities change

🎯 Why MCP Nova?

| Without Nova | With Nova v0.3.0 | |-------------|------------------| | ❌ Repeat context every session | ✅ AI automatically maintains context | | ❌ Manual searches & copy-paste | ✅ Proactive search triggers | | ❌ Lost project details | ✅ Project-isolated memory | | ❌ No memory across tools | ✅ Seamless workflow integration |

Validated Token Savings: 26-87% depending on usage pattern

🚀 Quick Start (2 minutes)

1. Install

# Standard installation
npm install -g @nova-mcp/mcp-nova

# Silent installation (recommended)
npm install -g @nova-mcp/mcp-nova --silent

# Minimal output installation  
npm install -g @nova-mcp/mcp-nova --no-progress --no-audit

2. Configure Your AI Assistant

🖥️ Claude Desktop

Add to config file:

• Windows: %APPDATA%\Claude\claude_desktop_config.json
• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "mcp-nova": {
      "command": "mcp-nova"
    }
  }
}

💻 Claude Code

# Windows (recommended)
claude mcp add mcp-nova node "%APPDATA%\npm\node_modules\@nova-mcp\mcp-nova\nova-memory-mcp.mjs"

# macOS (recommended)
claude mcp add mcp-nova node "/usr/local/lib/node_modules/@nova-mcp/mcp-nova/nova-memory-mcp.mjs"

# Linux
claude mcp add mcp-nova mcp-nova

# Alternative: Find your npm global path
# npm config get prefix

🚀 Cursor IDE

Create .cursor/mcp.json in your project:

{
  "mcpServers": {
    "mcp-nova": {
      "command": "mcp-nova"
    }
  }
}

3. Project Configuration (Optional)

Create nova-memory.config.js in your project root:

module.exports = {
  project: {
    projectPath: __dirname,
    projectName: "My Project"
  },
  ai: {
    proactive_search: true,
    entity_detection: true,
    silent_operations: true,
    search_mode: "smart" // smart, precise, fast, balanced
  },
  database: {
    path: ".nova/project-memory.db"
  }
};

4. Restart & Enjoy!

Restart your application to load MCP Nova.

🤖 AI Schema System - The Magic Behind v0.3.0

Proactive Behavior in Action

You: "I need to implement user authentication"
AI: *Automatically searches memory*
"Found 3 auth patterns. Your UserService uses JWT with 30-min TTL..."

You: "Fix the database timeout error"  
AI: *Auto-searches error solutions*
"Found previous fix: increased timeout to 30s, also connection pooling..."

Silent Operations

All 9 tools work invisibly in the background:

// AI can operate without showing output to user
memory({ action: "store", content: "...", silent: true })
board({ action: "create", title: "...", silent: true })
quick({ action: "save", content: "...", silent: true })

Entity Detection & Auto-Search

You: "The PaymentService needs refactoring"
AI: *Detects 'PaymentService' → searches automatically*
"PaymentService found - uses Stripe API v2, here's the refactor plan..."

You: "Update AuthenticationService security"
AI: *Searches AuthenticationService history*  
"Critical: Found security alert - migrate from BCrypt to Argon2..."

AI Mode Access

help({ ai_mode: true })
// Returns complete schemas with:
// - All proactive triggers
// - Entity detection patterns
// - Silent operation examples  
// - Command recognition rules

🛠️ 9 Integrated Tools

| Tool | Purpose | AI Features | |------|---------|-------------| | memory | Smart storage + versioning | Silent storage, auto-deduplication, entity evolution | | board | Task management | Background task sync, AI-aware priorities | | workflow | Development phases | Silent task creation, auto-phase detection | | quick | Speed shortcuts | One-command AI operations, background saves | | relationships | Knowledge graph | Silent relationship mapping, dependency detection | | analysis | Pattern insights | Background analysis, conflict detection | | project | Multi-project support | Auto project switching, isolated contexts | | settings | Preferences | AI-optimized defaults, silent config updates | | help | Interactive guide | AI mode access, complete schema exploration |

💡 Smart Versioning Examples

Entity Evolution Tracking

You: "UserService uses JWT tokens with 30min TTL"
AI: "Saved! Version 1 of UserService tracked"

You: "UserService now uses refresh tokens with 7-day TTL"  
AI: "Version 2 created! UserService authentication evolved"

You: "Show UserService evolution"
AI: "UserService versions:
- v2: Uses refresh tokens with 7-day TTL (current)  
- v1: Uses JWT tokens with 30min TTL (previous)"

// Query version history
memory({ action: "versions", entity_name: "UserService" })

Duplicate Prevention

You: "CacheService uses Redis"
AI: "Saved!"

You: "CacheService uses Redis"  // Exact same info
AI: "Duplicate detected - no new version needed"
