# 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

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

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

• 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

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

# 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

Safely archives your current database and creates a fresh empty one.

# 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

Create a backup without resetting (keeps current database).

# Basic archive
npm run db:archive

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

View all your database backups.

npm run db:list

Example output:

📦 Database Archives

Restore a previous database from archive.

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

Check your current database status.

npm run db:stats

Example output:

📊 Current Database Statistics
==================================================
Contacts: 546
Entries: 1,234
Size: 45.32 KB

Manage contact history entries with full CRUD operations.

# 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)
================================================================================

  Content: Sent project proposal via email. Awaiting feedback by Friday...

Archives are stored in data/archives/ with descriptive names:

• crm-backup-2025-06-04T19-15-35.sqlite (automatic timestamp)
• crm-backup-2025-06-04T19-15-35-cleanup.sqlite (with reason)
• crm-backup-2025-06-04T19-15-35-before-restore.sqlite (automatic safety backup)

• ✅ Never Deletes Data: All operations archive before making changes
• ✅ Automatic Timestamps: Every archive is uniquely named
• ✅ Safety Backups: Restore operations backup current state first
• ✅ Reason Tracking: Optional reasons help track why archives were made
• ✅ Easy Recovery: Simple commands to restore any previous state

# Comprehensive test suite (recommended) - uses database isolation
npm run test:comprehensive

# Individual test phases:
# Database management tests
npm run test:db

# Core functionality tests (Phase B)
cd tests && npx tsx run-phase-b-tests.ts

# Advanced tests - edge cases and performance (Phase C) 
cd tests && npx tsx run-phase-c-tests.ts

# Legacy comprehensive test runner
