Namecom Registrar

Name.com Domain Registrar & DNS Manager

MCP server providing nine tools for domain registration and DNS management against the Name.com CORE API (v1).

Environment Variables

Set credentials before starting the server:

Generate tokens at Account > Security > API Access. For sandbox testing, create sandbox credentials there and set only NAMECOM_USERNAME_TEST and NAMECOM_TOKEN_TEST (leave production vars unset); the server then targets the sandbox API.

Security & trust

• Token scope: Authenticates via standard Name.com API token. Name.com does not currently offer per-operation token scopes; the recommended hardening is IP whitelisting (Account > Security > API Access) to restrict the token to your deployment environment. Use sandbox credentials during initial setup.
• Purchases: register_domain enforces a code-level human-in-the-loop gate — it is not possible to complete a purchase without first calling dryRun: true. The dry-run response includes a one-time purchaseToken (6-digit code, valid 10 minutes, single-use, bound to the specific domain). The actual purchase call requires passing that token back; without it the tool returns an error. This is not just a documented guideline — the token gate is enforced in code. For production, fund the account with Name.com account credit instead of attaching a credit card when possible — that limits exposure if credentials are ever compromised. Otherwise use a payment method with spending limits or alerts.
• Install & supply chain: This skill installs the npm package namecom-clawbot. The package is published with signed npm provenance (GitHub Actions), so you can verify on the npm package page that the build matches the GitHub repo. Review the repo and package before installing. To limit risk, run the MCP server in an isolated environment (e.g. container or VM) and use sandbox credentials first.

Running the Server

# Install & build
npm install && npm run build

# Run (stdio transport — used by MCP hosts like Cursor)
node dist/src/index.js

Or add to your MCP host config:

{
  "mcpServers": {
    "namecom-registrar": {
      "command": "node",
      "args": ["dist/src/index.js"],
      "env": {
        "NAMECOM_USERNAME": "<your-username>",
        "NAMECOM_TOKEN": "<your-api-token>"
      }
    }
  }
}

Tools

check_domain

Check availability and pricing for up to 50 specific domain names at once. Returns purchase price (USD), renewal price, and premium status.

Always call this before register_domain to confirm availability and get pricing for premium domains.

search_domain

Keyword-based domain search. Provide a keyword and optionally filter by TLDs to get suggested available domain names with pricing. Use this when the user wants to brainstorm names rather than check a specific one.

register_domain

Provisions and registers a domain via the account’s payment settings. Automatically enables WHOIS privacy and registrar lock.

Required confirmation flow (enforced in code):

1. Call with dryRun: true — returns a quote (domain, years, estimated cost) plus a purchaseToken. No charge made.
2. Show the user the quote and get explicit confirmation.
3. Call again with dryRun: false and pass the purchaseToken from step 1.

The purchaseToken is a one-time 6-digit numeric code (e.g. 847291) valid for 10 minutes and bound to the specific domain name — easy to relay via Telegram, WhatsApp, or read aloud. Passing an incorrect, expired, or already-used token returns an error. You cannot skip to step 3 — there is no way to complete a purchase without a valid token from a prior dry-run.

For premium domains, pass the purchasePrice and purchaseType values from check_domain. For safety, prefer funding the Name.com account with account credit rather than a credit card when possible.

list_domains

List all domains in the account with expiration dates, autorenew/lock/privacy status. Use to see what the user already owns.

get_domain

Get detailed info for a single domain — contacts, nameservers, expiration, renewal pricing.

set_nameservers

Replace a domain's nameservers. Use when pointing a domain to Cloudflare, Route 53, Fly.io DNS, etc.

manage_dns

Create, delete, or list DNS records. Supported types: A, AAAA, CNAME, MX, TXT, ANAME, NS, SRV.

• Use action="list" to see all records and get record IDs for deletion
• Use host="" or host="@" for apex records, host="*" for wildcard
• MX and SRV records require priority

solve_dns01_challenge

End-to-end ACME DNS-01 challenge workflow:

1. Creates _acme-challenge TXT record with the challenge digest
2. Polls Google DNS and Cloudflare DNS every 5s until global propagation (up to 2 min)
3. Cleans up the TXT record on timeout or error

Returns the recordId so the caller can delete the record after certificate validation completes.

update_ddns

Dynamic DNS updater for residential/home-lab IPs:

1. Detects the machine's current public IPv4 via ipify
2. Finds the existing A record for the given host
3. Updates it if the IP changed, creates it if none exists, or skips if already correct

Example Workflows

Find and buy a cheap .dev domain, set up a wildcard A record:

1. search_domain with keyword="coolproject", tldFilter=["dev", "app"]
2. Pick the cheapest purchasable result
3. register_domain with the chosen name
4. manage_dns → action="create", host="*", type="A", answer="<ip>"

See what domains you already own and check one's details:

1. list_domains to get the full inventory
2. get_domain with a specific domain to see contacts, nameservers, expiration

Update DDNS after IP change:

1. update_ddns with domainName="example.com", host="home"
2. Tool auto-detects the new public IP and patches the A record

Solve an ACME DNS-01 challenge for Let's Encrypt:

1. solve_dns01_challenge with domainName="example.com", challengeValue="<digest>"
2. Wait for the tool to confirm propagation
3. Complete ACME validation with the CA
4. manage_dns → action="delete", recordId=<id from step 1> to clean up
