Cloudflare DNS Analytics

Monitor DNS performance and configuration using the DNS Analytics MCP server.

Available Tools

| Tool | Purpose | |------|---------| | zones_list | List all zones under the active account | | dns_report | Get DNS performance report for a zone over a time period | | show_account_dns_settings | View DNS settings at the account level | | show_zone_dns_settings | View DNS settings for a specific zone |

Common Workflows

DNS Health Check

Use zones_list to identify zones
Use dns_report for each zone to check performance
Review metrics for latency, query volume, errors

Configuration Audit

Use show_account_dns_settings for account-level settings
Use show_zone_dns_settings for zone-specific settings
Compare settings across zones for consistency

Performance Investigation

Identify the zone with zones_list
Pull dns_report for the relevant time frame
Analyze query patterns and response times

DNS Report Metrics

The DNS report typically includes:

Query volume over time
Response time distribution
Query types (A, AAAA, CNAME, etc.)
Response codes (NOERROR, NXDOMAIN, etc.)
Geographic distribution

Integration with Workers

For Workers using custom domains:

Verify zone configuration with show_zone_dns_settings
Check DNS report for the zone
Correlate with Workers observability data

Troubleshooting

| Issue | Investigation Steps | |-------|---------------------| | Slow DNS resolution | Check dns_report for latency metrics | | Missing records | Verify show_zone_dns_settings | | High error rates | Review response codes in dns_report | | Zone not found | List zones with zones_list |

Tips

Zone IDs from zones_list are needed for other operations
DNS reports can span custom time ranges
Account settings may override zone settings
Use with observability tools for full-stack debugging
