## 📦 Installation

### Prerequisites
- Node.js 18+ 
- npm or yarn

### Setup
```bash
# Clone the repository
git clone <repository-url>
cd mcp-crm

# Install dependencies
npm install

# Build the project
npm run build

# Start the server
npm run start:crm
```

## 🔧 Configuration

### MCP Integration
Add to your `.cursor/mcp.json` or MCP client configuration:

```json
{
  "mcpServers": {
    "mcp-crm": {
      "command": "node",
      "args": ["./build/crm-server.js"],
      "cwd": "/path/to/mcp-crm"
    }
  }
}
```

### Database
- **Location**: `data/crm.sqlite`
- **Type**: SQLite 3
- **Auto-created**: Database and tables are automatically initialized
- **Git Ignored**: Database files and archives are excluded from version control for security and size reasons

## 🗄️ Database Management

The CRM system includes powerful database management commands for safely resetting, archiving, and restoring your data.

### Quick Commands

```bash
# Reset database (archive current, create fresh)
npm run db:reset

# Archive current database (backup without reset)
npm run db:archive

# List all archived databases
npm run db:list

# Show current database statistics
npm run db:stats

# Contact entry management
npm run db:list-entries        # List all contact entries
npm run db:list-entries 1      # List entries for contact ID 1
npm run db:list-entries "" 10  # List 10 most recent entries (all contacts)
npm run db:view-entry 1        # View detailed entry
npm run db:delete-entry 1      # Delete entry by ID
npm run db:update-entry 1 content "Updated content"  # Update entry field

# Show help for database commands
npm run db:help
```

### Detailed Usage

#### Reset Database
**Safely archives your current database and creates a fresh empty one.**

```bash
# Basic reset
npm run db:reset

# Reset with reason (helpful for tracking)
npm run db:reset cleanup
npm run db:reset "testing-new-features"
```

**What happens:**
1. 📦 Current database is archived with timestamp
2. 🗑️ Current database is removed
3. ✅ Fresh empty database is created
4. 🛡️ Your data is safely preserved in archives

#### Archive Database
**Create a backup without resetting (keeps current database).**

```bash
# Basic archive
npm run db:archive

# Archive with reason
npm run db:archive "before-major-update"
```

#### List Archives
**View all your database backups.**

```bash
npm run db:list
```

**Example output:**
```
📦 Database Archives
==================================================
📁 crm-backup-2025-06-04T19-15-35-cleanup.sqlite
   Created: 6/4/2025, 7:15:35 PM
   Size: 45.32 KB
   Path: /data/archives/crm-backup-2025-06-04T19-15-35-cleanup.sqlite

📁 crm-backup-2025-06-03T14-22-18.sqlite
   Created: 6/3/2025, 2:22:18 PM
   Size: 42.17 KB
   Path: /data/archives/crm-backup-2025-06-03T14-22-18.sqlite
```

#### Restore from Archive
**Restore a previous database from archive.**

```bash
npm run db:list  # First, see available archives
# Then restore specific archive (replace with actual filename):
npx tsx scripts/database-manager.ts restore crm-backup-2025-06-04T19-15-35.sqlite
```

**What happens:**
1. 📦 Current database is archived (safety backup)
2. 🔄 Selected archive is restored as current database
3. ✅ Your data is back to the archived state

#### Database Statistics
**Check your current database status.**

```bash
npm run db:stats
```

**Example output:**
```
📊 Current Database Statistics
==================================================
Contacts: 546
Entries: 1,234
Size: 45.32 KB
```

### Contact Entry Management
**Manage contact history entries with full CRUD operations.**

```bash
# List contact entries
npm run db:list-entries                    # All entries (newest first)
npm run db:list-entries 1                  # All entries for contact 1
npm run db:list-entries "" 10              # 10 most recent entries (all contacts)
npm run db:list-entries 1 5                # 5 most recent entries for contact 1

# View detailed entry
npm run db:view-entry 2                    # View entry ID 2 with full content

# Update entry
npm run db:update-entry 2 content "New content here"     # Update content
npm run db:update-entry 2 subject "New subject"          # Update subject
npm run db:update-entry 2 entry_type note               # Update type

# Delete entry
npm run db:delete-entry 2                  # Delete entry ID 2 (with confirmation)
```

**Entry fields you can update:**
- `entry_type`: call, email, meeting, note, task
- `subject`: Brief title/subject of the entry
- `content`: Detailed content of the entry

**Example entry list output:**
```
📝 Contact Entries
   Showing 3 most recent entries (limited to 10)
================================================================================
Entry #5 (Jane Smith)
  Type: CALL
  Subject: Follow-up discussion
  Date: 2025-06-04 15:30:00
