MCP server for DNSimple — domains, DNS zone records, availability, pricing and contacts. Hosted by usefulapi — connect from Claude, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"dnsimple": {
"url": "https://dnsimple.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"dnsimple": {
"type": "http",
"url": "https://dnsimple.usefulapi.io/mcp"
}
}
}Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
The login page asks for your DNSimple API token.
Find it in DNSimple → Account → Automation → API tokens (an account API access token). Your token is used only to call the API on your behalf and to derive a private account id; it is never shown to anyone.
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 DNSimple API token. 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.
Turn on the DNSimple connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
dnsimple_whoami | read | Who am I Identify the authenticated account/user for the current API token. Use this to discover your account id (data.account.id). API: GET /whoami. |
dnsimple_list_domains | read | List domains List the domains in the account, with pagination and optional filters. API: GET /{account}/domains. |
dnsimple_get_domain | read | Get a domain Retrieve a single domain by name or id. API: GET /{account}/domains/{domain}. |
dnsimple_list_zone_records | read | List zone records List the DNS records in a zone, with pagination and optional filters. API: GET /{account}/zones/{zone}/records. |
dnsimple_get_zone_record | read | Get a zone record Retrieve a single DNS record in a zone by its numeric id. API: GET /{account}/zones/{zone}/records/{record}. |
dnsimple_check_domain | read | Check domain availability Check whether a domain is available to register. Returns { domain, available, premium }. API: GET /{account}/registrar/domains/{domain}/check. |
dnsimple_get_domain_prices | read | Get domain prices Retrieve the registration, renewal, and transfer prices for a domain. API: GET /{account}/registrar/domains/{domain}/prices. |
dnsimple_list_zones | read | List zones List the DNS zones in the account, with pagination and optional filters. API: GET /{account}/zones. |
dnsimple_list_contacts | read | List contacts List the contacts in the account (used as domain registrants). API: GET /{account}/contacts. |
dnsimple_create_zone_record | write | Create a zone record Create a new DNS record in a zone. Additive — it adds a record without touching existing ones. API: POST /{account}/zones/{zone}/records. |
dnsimple_update_zone_record | write | Update a zone record Update an existing DNS record. WARNING: mutates LIVE DNS — changing content/ttl takes effect for real resolution. Only the fields you provide are sent. API: PATCH /{account}/zones/{zone}/records/{record}. |
dnsimple_delete_zone_record | write | Delete a zone record Delete a DNS record from a zone. WARNING: permanently removes a live DNS record. API: DELETE /{account}/zones/{zone}/records/{record}. Returns 204 (no body). |
dnsimple_usage_status | Usage status (free-tier meter) Report the caller's current free-tier usage this month: calls used, monthly limit, remaining, and whether the cap is reached. Read-only; does not count against the meter. | |
dnsimple_request_feature | Request a missing feature Tell usefulapi that the user needs something the DNSimple 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. | |
dnsimple_upgrade | Upgrade to Pro (unlimited) Subscribe to the Pro plan for UNLIMITED DNSimple tool calls (the free tier caps monthly usage). Choose monthly ($9/month) or yearly ($90/year — 2 months free) billing. Returns a Stripe Checkout link to open in your browser; after payment your account upgrades automatically. Does not count against the meter. | |
dnsimple_cancel_subscription | Cancel the Pro subscription Cancel the caller's DNSimple Pro subscription at the end of the paid period (no refund for the current period; unlimited calls continue until then, then the free tier applies). Requires confirm: true. Run dnsimple_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 100 tool calls / month |
| Pro | $9/mo · $90/yr | Unlimited |
Pro covers this DNSimple server only. Subscribe with dnsimple_upgrade (it returns a Stripe Checkout link). Cancel any time with dnsimple_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running dnsimple_upgrade before then undoes the cancel. Or write to [email protected].
No. usefulapi is an independent service. It is not affiliated with or endorsed by DNSimple. The server calls the DNSimple API with your own DNSimple access, so it sees only the data that your account can see.
The login page asks for your DNSimple API token. See Before you connect for where to find it.
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 DNSimple API token. 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.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the DNSimple 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 DNSimple.
Yes, if you approve it. 3 of the 12 DNSimple tools can create or change data. The other 9 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 100 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls, for this DNSimple server only. Run dnsimple_usage_status to see how many calls you used.
Ask the AI to run dnsimple_upgrade: it returns a Stripe Checkout link. To cancel, run dnsimple_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with dnsimple_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.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, 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.
