rdap-mcp-server is an MCP server for looking up domain names, IP addresses, and Autonomous System Numbers through RDAP. It exposes separate tools for each lookup type.

Key features

  1. 01Look up domain RDAP information
  2. 02Look up IP RDAP information
  3. 03Look up ASN RDAP information

Use cases

  1. 01Inspect registration data for a domain
  2. 02Look up RDAP details for an IP address
  3. 03Find RDAP information for an ASN

MCP support

Exposes the `rdap_domain`, `rdap_ip`, and `rdap_as` tools to MCP clients for RDAP lookups.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "rdap": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/inspector"
      ]
    }
  }
}
Run commandnpx -y @modelcontextprotocol/inspector

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Packages
npm@modelcontextprotocol/inspector

Tools

No tool list yet

Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
