Connect [DomScan](https://domscan.net) to Claude, Cursor, VS Code and any [Model Context Protocol](https://modelcontextprotocol.io/) client to run DNS, WHOIS/RDAP, SSL/TLS, subdomain, availability, valuation, email-security and brand-protection lookups straight from your assistant.\n\nDomScan is a domain intelligence platform that exposes its data over one REST API and a hosted MCP server. This repository documents the MCP server: how to connect it, what tools it exposes, and how to use it in agent pipelines.\n\n- Website: https://domscan.net\n- MCP endpoint: `https://domscan.net/mcp` (Streamable HTTP)\n- Transport: Streamable HTTP (remote)\n- Auth: OAuth discovery (recommended) or a DomScan API key\n\n## Quick start\n\n### OAuth-aware clients\n\nAdd `https://domscan.net/mcp` as a remote MCP server. DomScan publishes OAuth protected-resource and authorization-server metadata, so compatible clients can discover and complete authentication without a manually configured API key.\n\n```json\n{\n  \"mcpServers\": {\n    \"domscan\": {\n      \"url\": \"https://domscan.net/mcp\"\n    }\n  }\n}\n```\n\n### Claude Desktop / Claude Code with an API key\n\nAdd to your MCP config (`claude_desktop_config.json` or `.mcp.json`):\n\n```json\n{\n  \"mcpServers\": {\n    \"domscan\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"mcp-remote\",\n        \"https://domscan.net/mcp\",\n        \"--header\",\n        \"Authorization: Bearer ${DOMSCAN_API_KEY}\"\n      ],\n      \"env\": { \"DOMSCAN_API_KEY\": \"your-api-key\" }\n    }\n  }\n}\n```\n\n### Native remote URL with an API key\n\n```json\n{\n  \"mcpServers\": {\n    \"domscan\": {\n      \"url\": \"https://domscan.net/mcp\",\n      \"headers\": { \"Authorization\": \"Bearer your-api-key\" }\n    }\n  }\n}\n```\n\nGet an API key from the [DomScan dashboard](https://domscan.net/dashboard). OAuth is preferred when the client supports it. API keys remain available for clients that need explicit header authentication.\n\n## Local MCP wrapper\n\nThis repository includes a runnable stdio wrapper for clients that cannot connect directly to the hosted Streamable HTTP endpoint. It forwards requests to `https://domscan.net/mcp` using `DOMSCAN_API_KEY`.\n\n```bash\nnpm install\nDOMSCAN_API_KEY=your-api-key npm start\n```\n\nIf no API key is configured, the wrapper still starts and exposes only the read-only `domscan_mcp_status` tool. This lets MCP registries inspect and validate the server without granting access to domain-intelligence operations.\n\n### Docker\n\n```bash\ndocker build -t domscan-mcp .\ndocker run --rm -i -e DOMSCAN_API_KEY=your-api-key domscan-mcp\n```\n\nThe local wrapper uses API-key authentication. Clients that support remote Streamable HTTP and OAuth should continue connecting directly to `https://domscan.net/mcp`; OAuth remains the recommended option for those clients.\n\n## What it can do\n\nThe server exposes domain-intelligence tools across these areas:\n\n- **DNS**: record lookups (A, AAAA, MX, TXT, NS, CNAME, CAA), full record dumps, propagation checks, DNS security.\n- **WHOIS / RDAP**: registration data, WHOIS history, reverse WHOIS, RDAP.\n- **SSL/TLS**: certificate audit, chain inspection, grade, expiry checks, deep scan, certificate search.\n- **Subdomains**: subdomain enumeration and discovery.\n- **Availability and valuation**: domain availability (single and bulk), appraisal, name suggestions.\n- **Email security**: SPF, DKIM, DMARC validation and DNSSEC posture.\n- **Brand protection**: typosquatting detection, brand monitors and scans.\n- **Infrastructure**: IP lookup, hosting detection, ASN, technology/stack detection, MAC vendor lookup.\n\nSee the [DomScan API documentation](https://domscan.net/docs) and [MCP setup guide](https://domscan.net/mcp-domain-checker).\n\n## Why MCP\n\nMCP lets an AI assistant call DomScan directly: ask \"is acme.io available, and who owns the look-alikes?\" and the agent runs availability, WHOIS and typosquatting tools and answers in one turn. The same server powers automated workflows (monitoring, due diligence, brand protection) without custom integration code.\n\n## Links\n\n- Product: https://domscan.net\n- API documentation: https://domscan.net/docs\n- MCP setup guide: https://domscan.net/mcp-domain-checker\n- MCP spec: https://modelcontextprotocol.io/\n- Datasets and APIs: https://domscan.net/tools\n\n## License\n\nMIT.
