What you can do with ClouDNS in Claude and ChatGPT

For domain owners and system administrators who manage DNS zones, records and monitoring in ClouDNS.

List the DNS zones of an account

List the zones, or the zones whose name matches a keyword. Open one zone to see its status and whether it is a master or slave zone.

Read the TXT records on one host

List the records of a zone for one host, such as _dmarc, or for one record type. Use host_like to match part of a host name. The tool reads master zones only.

Add a domain verification TXT record

List the TXT records first to check that the record is not there. Then add the verification record to a master zone. This changes live DNS, and a repeat call adds a duplicate.

Changes data

Check failover and monitoring status

List the monitoring checks to see which are down or paused. Read the failover settings of one record to see whether its failover is active.

How do I connect ClouDNS?

Before you connect

The login page asks for your API user ID (auth-id) and API password (auth-password).

Create an API user under API & Resellers in ClouDNS, then paste its auth-id and auth-password. Your credentials are used only to call the ClouDNS API on your behalf.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http cloudns https://cloudns.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "cloudns": {
      "url": "https://cloudns.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "cloudns": {
      "type": "http",
      "url": "https://cloudns.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add cloudns --url https://cloudns.usefulapi.io/mcp
codex mcp login cloudns

Other clients

Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.

https://cloudns.usefulapi.io/mcp

Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your API user ID (auth-id) and API password (auth-password). If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Each paid plan covers this ClouDNS server only. Ask your AI to run cloudns_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with cloudns_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with cloudns_upgrade before then undoes the cancel.

    Add a TXT record to a master zone. This changes live DNS. Calling it again with the same values adds a duplicate record.

Your usefulapi plan · 4

  • Usage status (free-tier meter)cloudns_usage_status
    Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter.
  • Request a missing featurecloudns_request_feature
    Tell usefulapi that the user needs something the ClouDNS tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
  • Upgrade to Pro or Pro+cloudns_upgrade
    Get a paid plan for ClouDNS (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
  • Cancel the Pro subscriptioncloudns_cancel_subscription
    Cancel the caller's ClouDNS Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run cloudns_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with ClouDNS in Claude or ChatGPT?

List the DNS zones of an account. Read the TXT records on one host. Add a domain verification TXT record. Check failover and monitoring status. See what you can do for the details.

Is this an official ClouDNS product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by ClouDNS. The server calls the ClouDNS API with your own ClouDNS access, so it sees only the data that your account can see.

Can I connect ClouDNS to Claude or ChatGPT?

Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.

What do I need to connect?

The login page asks for your API user ID (auth-id) and API password (auth-password). See Before you connect for where to find them.

Do I put my ClouDNS key or an Authorization header in the client config?

No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your API user ID (auth-id) and API password (auth-password). If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my ClouDNS credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the ClouDNS API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in ClouDNS.

Can the AI change my ClouDNS data?

Yes, if you approve it. 1 of the 6 ClouDNS tools can create or change data. The other 5 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this ClouDNS server only. Cancel any time: your paid plan then runs to the end of the paid period. Run cloudns_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run cloudns_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run cloudns_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a ClouDNS tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with cloudns_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
