cloudflare-registrar

Instructions for using Cloudflare Registrar, Cloudflare's domain-name registration service, to check domains, prices, and registrations.

In plain words
What is it for?
It helps check domain availability and pricing, list existing registrations, and register a domain with specified renewal and privacy settings.
Why use it?
It adds a safety check before registration and requires confirmation before making a billable, non-refundable purchase.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cloudflare-registrar scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Cloudflare Registrar

Use for Cloudflare Registrar domain availability, pricing, listing, and registration.

Defaults

  • MCP: cloudflare-openclaw
  • Account: OPENCLAW_CLOUDFLARE_ACCOUNT_ID
  • Token: OPENCLAW_CLOUDFLARE_API_TOKEN
  • Secrets: follow the root secret rule; export only needed Cloudflare vars for one command.

Guardrails

  • Always run domain-check immediately before registration.
  • Registration is billable/non-refundable. Ask Peter for explicit confirmation before POST /registrar/registrations.
  • Do not print tokens.

Commands

Check availability/pricing:

npx mcporter call cloudflare-openclaw.execute code='async () => {
  return cloudflare.request({
    method: "POST",
    path: `/accounts/${accountId}/registrar/domain-check`,
    body: { domains: ["example.com"] }
  });
}'

Register after confirmation:

npx mcporter call cloudflare-openclaw.execute code='async () => {
  return cloudflare.request({
    method: "POST",
    path: `/accounts/${accountId}/registrar/registrations`,
    body: { domain_name: "example.com", auto_renew: false, privacy_mode: "redaction" }
  });
}'

List registrations:

npx mcporter call cloudflare-openclaw.execute code='async () => {
  return cloudflare.request({
    method: "GET",
    path: `/accounts/${accountId}/registrar/registrations`
  });
}'
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
