Cloudflare

Cloudflare API Skill

Control Cloudflare infrastructure: DNS management, CDN, security, Workers, and more.

Authentication

API token required. Get one from: https://dash.cloudflare.com/profile/api-tokens

Recommended permissions:

• Zone:Zone:Read
• Zone:Zone:Edit
• Zone:DNS:Read
• Zone:DNS:Edit

Store in ~/.config/cloudflare/token:

mkdir -p ~/.config/cloudflare
echo -n "YOUR_API_TOKEN" > ~/.config/cloudflare/token
chmod 600 ~/.config/cloudflare/token

SSL/TLS

# Get SSL mode
python3 scripts/cloudflare.py ssl get <domain>

# Set SSL mode (off, flexible, full, strict)
python3 scripts/cloudflare.py ssl set <domain> --mode full

# Always use HTTPS
python3 scripts/cloudflare.py ssl https <domain> --on

Page Rules

# List page rules

# Add redirect rule
python3 scripts/cloudflare.py rules add <domain> --match "example.com/*" --redirect "https://new.com/$1"

# Delete rule
python3 scripts/cloudflare.py rules delete <domain> <rule_id>

Firewall

# List firewall rules
python3 scripts/cloudflare.py firewall list <domain>

# Block IP
python3 scripts/cloudflare.py firewall block <domain> --ip 1.2.3.4 --note "Spammer"

# Block country
python3 scripts/cloudflare.py firewall block <domain> --country CN --note "Block China"

python3 scripts/cloudflare.py firewall allow <domain> --ip 1.2.3.4

# Challenge (captcha) for IP range
python3 scripts/cloudflare.py firewall challenge <domain> --ip 1.2.3.0/24

Analytics

# Get traffic stats (last 24h)
python3 scripts/cloudflare.py analytics <domain>

# Get stats for date range
python3 scripts/cloudflare.py analytics <domain> --since 2024-01-01 --until 2024-01-31

Workers (Serverless)

python3 scripts/cloudflare.py workers list

# Deploy worker
python3 scripts/cloudflare.py workers deploy <name> --script worker.js

# Delete worker
python3 scripts/cloudflare.py workers delete <name>

DNS Record Types

Proxy Status (Orange Cloud)

• Proxied (on): Traffic goes through Cloudflare CDN — caching, DDoS protection, hides origin IP
• DNS only (off): Direct connection to origin — use for mail servers, non-HTTP services

# Enable proxy
python3 scripts/cloudflare.py dns add example.com --type A --name @ --content 1.2.3.4 --proxied

# Disable proxy (DNS only)
python3 scripts/cloudflare.py dns add example.com --type A --name mail --content 1.2.3.4 --no-proxy

SSL Modes

Common Workflows

Add a New Domain

# 1. Add zone to Cloudflare
python3 scripts/cloudflare.py zones add example.com

# 2. Note the nameservers (e.g., adam.ns.cloudflare.com, bella.ns.cloudflare.com)

# 3. Update nameservers at your registrar

# 4. Add DNS records
python3 scripts/cloudflare.py dns add example.com --type A --name @ --content 1.2.3.4 --proxied
python3 scripts/cloudflare.py dns add example.com --type CNAME --name www --content example.com --proxied

# 5. Set SSL to strict
python3 scripts/cloudflare.py ssl set example.com --mode strict

Migrate DNS from Another Provider

# 1. Add zone (Cloudflare will scan existing records)
python3 scripts/cloudflare.py zones add example.com

# 2. Verify records imported correctly
python3 scripts/cloudflare.py dns list example.com

# 3. Add any missing records
python3 scripts/cloudflare.py dns add example.com --type MX --name @ --content mail.example.com --priority 10

# 4. Update nameservers at registrar

# 5. Wait for propagation, check status
python3 scripts/cloudflare.py zones status example.com

Set Up Email Records

# MX records
python3 scripts/cloudflare.py dns add example.com --type MX --name @ --content mx1.provider.com --priority 10
python3 scripts/cloudflare.py dns add example.com --type MX --name @ --content mx2.provider.com --priority 20

# SPF
python3 scripts/cloudflare.py dns add example.com --type TXT --name @ --content "v=spf1 include:_spf.provider.com ~all"

# DKIM
python3 scripts/cloudflare.py dns add example.com --type TXT --name selector._domainkey --content "v=DKIM1; k=rsa; p=..."

# DMARC
python3 scripts/cloudflare.py dns add example.com --type TXT --name _dmarc --content "v=DMARC1; p=quarantine; rua=mailto:dmarc@example.com"

Nameservers

When you add a domain, Cloudflare assigns two nameservers like:

• adam.ns.cloudflare.com
• bella.ns.cloudflare.com

Update these at your domain registrar. Zone stays "pending" until nameservers propagate.
