## 📦 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:**
```

```
#### 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)
