## Known Limitations
1. **Concurrent Users:** Currently designed for 1-2 concurrent users per instance
- *Mitigation:* Deploy multiple instances + load balancer for higher concurrency
2. **Stdio Transport:** Direct socket communication only
- *Mitigation:* Use HTTP proxy (Nginx) for network access
3. **Node 18+ Requirement:** Not compatible with older Node versions
- *Mitigation:* All modern RPi OS ships with compatible versions

## Recommendations
### Before Production Deployment
1. **Environment Configuration**
```bash
# Generate and secure your secrets
ATLAS_GATE_BOOTSTRAP_SECRET=$(openssl rand -hex 32)
ATLAS_GATE_ATTESTATION_SECRET=$(openssl rand -hex 32)
# Add to .env (git-ignored)
```
2. **Network Setup**
- Install TailScale on RPi: `curl -fsSL https://tailscale.com/install.sh | sh`
- Authenticate: `sudo tailscale up`
- Document TailScale IP for access
3. **Systemd Service**
- Use provided service template: `TAILSCALE_DEPLOYMENT.md`
- Enable autostart: `sudo systemctl enable atlas-gate`
- Configure log rotation: `sudo journalctl --vacuum-time=7d`
4. **Monitoring**
- Monitor process: `sudo systemctl status atlas-gate`
- Check logs: `sudo journalctl -u atlas-gate -f`
- Verify audit trail: `tail -f audit-log.jsonl`
5. **Backup Strategy**
- Daily backup of `/workspace`
- Archive audit logs periodically
- Version control for code changes
### Performance Optimization
For multiple concurrent users:
1. Deploy multiple instances
2. Configure load balancer (Nginx upstream)
3. Use centralized audit log store
4. Monitor memory and CPU usage
## Conclusion
**ATLAS-GATE MCP is ready for production deployment.**
All verification checks pass. The system is:
- ✅ Functionally complete
- ✅ Securely hardened
- ✅ Well documented
- ✅ Deployment-ready
- ✅ TailScale-compatible
### Next Steps
1. Run `node verify-complete-setup.js` to confirm all checks
2. Follow `TAILSCALE_DEPLOYMENT.md` for RPi + TailScale setup
3. Create `.env` with secure secrets
4. Deploy systemd service
5. Test remote access via TailScale
6. Configure monitoring and backups
7. Deploy to production
