### `lookup_domain_whois` (~325 tokens)

Look up domain WHOIS and RDAP records

Look up who registered a domain, when, and when it expires. Give domains, website URLs, or email addresses (up to 5,000). For each registrable domain the actor asks the registry's own RDAP server (from the IANA list), or its port 43 WHOIS server where there is no RDAP, and returns one row: registered true or false, registrar, created_at, updated_at, expires_at, domain_age_days, days_until_expiry, status codes, nameservers, dnssec, and the registrant organization and country where the registry publishes them. Rows with no dates published, error rows, and input that is not a domain come back free with a row_status saying so. A run that does not succeed is returned as an error with its run ID. Read-only; requires an APIFY_TOKEN; Apify charges per domain lookup.

Input parameters:

- `domain` (string): One domain, URL, or email address, for example stripe.com.
- `domains` (array): Domains, website URLs, or email addresses, up to 5,000. Subdomains are looked up as their registrable domain.
- `follow_registrar_rdap` (string): true (default) also reads the registrar's RDAP record for the abuse email and any registrant details it publishes.
- `include_raw` (string): true puts the registry's raw RDAP JSON or WHOIS text in raw_response. Default false.
- `max_charge_usd` (string): Optional. The run stops before a charge would pass this amount.

com.mambabuilt/mcp-whois-domain-lookup is listed in the public MCP registry as com.mambabuilt/mcp-whois-domain-lookup. Registrar, created and expiry dates, domain age, and nameservers per domain, from RDAP and WHOIS. This page covers its npm package (@mambalabsdev/mcp-whois-domain-lookup).

### Is the com.mambabuilt/mcp-whois-domain-lookup server safe to use?

com.mambabuilt/mcp-whois-domain-lookup scores 56 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the com.mambabuilt/mcp-whois-domain-lookup server expose?

com.mambabuilt/mcp-whois-domain-lookup exposes 1 tool: lookup_domain_whois. Their descriptions and schemas cost roughly 325 tokens of context every time the server is loaded.

### Is the com.mambabuilt/mcp-whois-domain-lookup server still maintained?

com.mambabuilt/mcp-whois-domain-lookup is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the com.mambabuilt/mcp-whois-domain-lookup server under?

com.mambabuilt/mcp-whois-domain-lookup declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the com.mambabuilt/mcp-whois-domain-lookup server?

VerifyMCP ran 15 checks on com.mambabuilt/mcp-whois-domain-lookup, covering Known CVEs, Install scripts, Dependency health, Source repository and 11 more. One item could not be completed, a gap on our side rather than a finding about com.mambabuilt/mcp-whois-domain-lookup: Malware scan. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
