## What the WHOIS & Domain Availability (RDAP) MCP server does

WHOIS & Domain Availability (RDAP) MCP server connects agent workflows to official Registration Data Access Protocol (RDAP) data for domain lookups. Its stated scope is domain WHOIS information and availability checking.

The returned domain information can include the registrar, expiration dates, and nameservers. These fields help an agent inspect who manages a domain, when its registration is due to expire, and which name servers are associated with it.

Availability checks are also supported. This makes the server relevant to workflows that need to screen a domain name before attempting registration, compare domain options, or review an existing domain’s registration details.

## How it works

The server uses official RDAP sources rather than describing a separate private WHOIS database. An MCP-compatible agent can use the server for domain-related requests, while RDAP supplies the underlying registration data.

The available material does not document a specific endpoint, request format, response schema, provider list, or transport configuration. Those implementation details should be verified in the source project before building a client or automated workflow around them.

## Tools and capabilities

The documented capabilities are:

- Looking up domain WHOIS data
- Checking domain availability
- Returning registrar information
- Returning domain expiry dates
- Returning nameserver information

The source description does not provide formal tool names or argument definitions, so callers should not assume a particular function name or parameter schema.

## Limitations and notes

WHOIS & Domain Availability (RDAP) MCP server is documented only at a high level in the supplied material. The README is unavailable, so installation steps, required environment variables, supported MCP clients, licensing, error behavior, and rate limits cannot be confirmed here.

RDAP results can vary by domain registry and may not contain every field for every domain. The supplied description confirms the listed data categories and availability checks, but does not specify coverage, freshness guarantees, or how unavailable or private registration data is represented.

Use the repository or Apify listing for operational details before deployment. In particular, verify how the server is started, how domains are passed to it, and whether its availability result is expressed as a boolean, status value, or another response format.
