# 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.jsonor 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"

- 📦 Current database is archived with timestamp
- 🗑️ Current database is removed
- ✅ Fresh empty database is created
- 🛡️ 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"

📦 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 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

- 📦 Current database is archived (safety backup)
- 🔄 Selected archive is restored as current database
- ✅ Your data is back to the archived state

📊 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_type: call, email, meeting, note, task
- subject: Brief title/subject of the entry
- content: Detailed content of the entry

📝 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 Content: Discussed project requirements and timeline. Next meeting scheduled... Entry #4 (John Doe) Type: EMAIL Subject: Proposal sent Date: 2025-06-04 14:15:00 Content: Sent project proposal via email. Awaiting feedback by Friday...

- 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
