DomainDetails MCP Server\n\nA Model Context Protocol (MCP) server that provides comprehensive domain research tools including RDAP, WHOIS, and DNS lookup capabilities.\n\n## Features\n\n- **RDAP First**: Uses modern RDAP protocol for structured domain data\n- **WHOIS Fallback**: Automatically falls back to WHOIS when RDAP fails\n- **Registry Detection**: Automatically detects the correct RDAP/WHOIS server for any TLD\n- **Comprehensive Coverage**: Supports 50+ TLDs including gTLDs and ccTLDs\n- **Easy Integration**: Works with any MCP-compatible client (Claude Desktop, IDEs, etc.)\n\n## Installation\n\n```bash\nnpm install domaindetails-mcp\n```\n\nOr use directly with npx:\n\n```bash\nnpx domaindetails-mcp\n```\n\n## Usage\n\n### Claude Desktop\n\nAdd to your Claude Desktop configuration file:\n\n**MacOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`\n\n**Windows**: `%APPDATA%\\Claude\\claude_desktop_config.json`\n\n```json\n{\n  \"mcpServers\": {\n    \"domaindetails\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"domaindetails-mcp\"]\n    }\n  }\n}\n```\n\n### Claude Code\n\nAdd to your Claude Code MCP settings:\n\n```bash\nclaude mcp add domaindetails -- npx -y domaindetails-mcp\n```\n\nOr manually add to `~/.claude/claude_desktop_config.json`:\n\n```json\n{\n  \"mcpServers\": {\n    \"domaindetails\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"domaindetails-mcp\"]\n    }\n  }\n}\n```\n\n### Cursor\n\nAdd to your Cursor MCP configuration at `~/.cursor/mcp.json`:\n\n```json\n{\n  \"mcpServers\": {\n    \"domaindetails\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"domaindetails-mcp\"]\n    }\n  }\n}\n```\n\n### Windsurf\n\nAdd to your Windsurf MCP configuration at `~/.codeium/windsurf/mcp_config.json`:\n\n```json\n{\n  \"mcpServers\": {\n    \"domaindetails\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"domaindetails-mcp\"]\n    }\n  }\n}\n```\n\n### Other MCP Clients\n\nFor any MCP-compatible client, use:\n- **Command**: `npx`\n- **Args**: `[\"-y\", \"domaindetails-mcp\"]`\n\nOr if installed globally:\n- **Command**: `domaindetails-mcp`\n\n## Available Tools\n\n### `domain_lookup`\n\nLook up comprehensive domain information using RDAP protocol with WHOIS fallback.\n\n**Parameters:**\n- `domain` (string, required): The domain name to look up (e.g., example.com)\n- `prefer_whois` (boolean, optional): If true, use WHOIS instead of RDAP as primary method\n- `include_raw` (boolean, optional): If true, include raw protocol response data\n\n**Example Response:**\n```json\n{\n  \"domain\": \"example.com\",\n  \"found\": true,\n  \"method\": \"rdap\",\n  \"timestamp\": \"2025-01-21T10:30:00Z\",\n  \"status\": [\"client transfer prohibited\"],\n  \"nameservers\": [\"ns1.example.com\", \"ns2.example.com\"],\n  \"rdap\": {\n    \"registration_date\": \"1995-08-14T04:00:00Z\",\n    \"expiration_date\": \"2025-08-13T04:00:00Z\",\n    \"contacts\": [...],\n    \"dnssec\": {...}\n  }\n}\n```\n\n## Supported TLDs\n\nThe server includes built-in registry detection for 50+ TLDs:\n\n**Generic TLDs**: com, net, org, info, biz, name, pro, xyz, top, site, online, tech, store, app, dev, io, ai, co, me, tv, cc\n\n**Country Code TLDs**: uk, ca, au, de, fr, nl, be, ch, at, it, es, se, no, dk, fi, ie, pl, cz, sk, hu, ro, bg, hr, si, lv, lt, ee\n\nFor unsupported TLDs, the server will attempt to fetch registry information from IANA's bootstrap service.\n\n## Related Packages\n\n- **[domaindetails](https://www.npmjs.com/package/domaindetails)** - CLI tool and library for domain lookups (includes this MCP server)\n\n##
