What is the RDAP MCP Server?

The RDAP MCP Server is a service specifically designed to query registration information of Internet resources. It uses the modern RDAP protocol (replacing the traditional WHOIS protocol) to obtain detailed information about domain names, IP addresses, and autonomous system numbers.

How to use the RDAP MCP Server?

You can easily deploy and use this service through a Docker container. It provides three main tools to query information about different types of Internet resources.

Applicable scenarios

Suitable for scenarios that require querying information about modern domain names (such as new TLDs like .dev that no longer support WHOIS), network security analysis, and any application that needs to obtain registration information of Internet resources.

Main features

Domain name query
Use the rdap_domain tool to query registration information of any domain name that supports the RDAP protocol.
IP address query
Use the rdap_ip tool to query registration and allocation information of IP addresses.
Autonomous system query
Use the rdap_as tool to query information related to autonomous system numbers (ASN).
Docker container support
Provides pre-built Docker images to simplify the deployment and usage process.
Advantages
Supports the modern RDAP protocol and can query new top-level domains that no longer support WHOIS.
Lightweight design, easy to deploy via Docker.
Provides three dedicated tools to handle different types of queries respectively.
Open-source project, can be freely modified and extended.
Limitations
Requires a Docker environment to run.
Only supports the RDAP protocol and does not provide traditional WHOIS queries.
The format of query results may vary depending on different registrars.

How to use

Install Docker
Ensure that your system has the Docker runtime environment installed.
Configure the MCP server
Add the server configuration to your MCP client configuration file.
Execute a query
Send a query request through the MCP client.

Usage examples

Query information about new top-level domains
When you need to query registration information of new top-level domains like .dev, traditional WHOIS tools may not work, but the RDAP MCP Server can obtain the information normally.
Network security investigation
When investigating a suspicious IP address, you can quickly query its registration information and the affiliated network.
