Value-Domain MCP

Lemon Domains is the unofficial Value-Domain MCP server.

Connections start read only, so your AI changes only what you allow.

“Which of my Value-Domain domains expire in the next 60 days?”
“Is auto-renew on for every domain at Value-Domain?”
“Did the nameservers change on any of my Value-Domain domains this week?”

Connect Value Domain to Lemon Domains

Three steps: create a read-only API key at Value Domain, add it to Lemon Domains, and your domains sync once a day from then on. Connect as many Value Domain accounts as you have.

Step 1

Create a read-only API key at Value Domain

Give it the least access you can

Value-Domain tokens cannot be limited to read-only: a token can use everything the API offers on your account, including DNS changes. Lemon Domains only calls the domain list. Reissue the token in API settings if you stop using Lemon Domains.

1Sign in to the Value-Domain control panel and open API settings (API設定, value-domain.com/vdapi/).
2Issue an API token if you do not have one, and copy it.
3If you limit the key to certain IP addresses, allow the Lemon Domains IP address shown on the connect page.

Open Value Domain API settings

Step 2

Add it to Lemon Domains

1Sign in to Lemon Domains (it's free), open Connections and choose Value Domain.
2Give the connection a friendly name, like “Value Domain personal” or “Value Domain clients”. Connect each Value Domain account separately.
3Paste your api token.
4Click Test connection. Lemon Domains checks the API key and shows how many domains it can see, without saving anything.
5Tick the checkbox to confirm you understand the risks, pick the project new domains go into, and click Connect and import. Your domains appear straight away and sync once a day after that.

Step 3

What Lemon Domains reads

Synced once a day

Domain names (including internationalised names)
Status, such as active, expired or pending transfer
Expiry and registration dates
Whether auto-renew is on

Read-only by design

Lemon Domains only ever sends read requests to Value Domain: each integration has a fixed list of read-only calls it may make, so it never renews, transfers or changes a domain. Your API key is encrypted at rest and never shown again.

If something goes wrong

Value Domain rejects the API key: Copy it again with no spaces at either end. Some registrars only show the secret once, so create a new key if you didn't save it.
The key has an IP restriction: Lemon Domains connects from 2.31.94.66. Add it to the API key's allowed IPs, or remove the restriction.
Some domains are missing: Make sure the API key belongs to the Value Domain account (or sub-account) that holds those domains. Connect each account separately.

Rather not use an API key? Import by paste or CSV

Copy your list from the Value Domain portal, paste it into Lemon Domains, and you're done. Re-import any time to refresh. Paste or CSV import needs no Value Domain credentials at all.

Open your Value Domain account

1Open your Value Domain account at value-domain.com and go to the domain list.
2If the list paginates, switch to "show all" or the largest page size so every Value Domain domain is visible.
3Copy the visible list, or export to CSV if Value Domain offers it from the account area.
4In Lemon Domains, click Import, paste the list or upload the CSV, and map the columns. Lemon Domains previews everything before it commits.
5Give the registrar account a friendly label (for example "Value Domain personal" or "Value Domain client work") so sub-accounts stay distinct.
