Setup
Install DomScan in your MCP client (Claude Desktop, Cursor, Windsurf, and others).
Repository: https://github.com/estevecastells/domscan-mcp
Follow the installation instructions in the repository README, then restart your MCP client.
Domain intelligence for AI agents. ConnectDomScanto Claude, Cursor, VS Code and anyModel Context Protocolclient to run DNS, WHOIS/RDAP, SSL/TLS, subdomain, availability, valuation, email-security and brand-protection lookups straight from your assistant.
DomScan 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.
Addhttps://domscan.net/mcpas 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.
{ "mcpServers": { "domscan": { "url": "https://domscan.net/mcp" } } }
Claude Desktop / Claude Code with an API key
Add to your MCP config (claude_desktop_config.jsonor.mcp.json):
{ "mcpServers": { "domscan": { "command": "npx", "args": [ "-y", "mcp-remote", "https://domscan.net/mcp", "--header", "Authorization: Bearer ${DOMSCAN_API_KEY}" ], "env": { "DOMSCAN_API_KEY": "your-api-key" } } } }
{ "mcpServers": { "domscan": { "url": "https://domscan.net/mcp", "headers": { "Authorization": "Bearer your-api-key" } } } }
Get an API key from theDomScan dashboard. OAuth is preferred when the client supports it. API keys remain available for clients that need explicit header authentication.
This repository includes a runnable stdio wrapper for clients that cannot connect directly to the hosted Streamable HTTP endpoint. It forwards requests tohttps://domscan.net/mcpusingDOMSCAN_API_KEY.
npm install DOMSCAN_API_KEY=your-api-key npm start
If no API key is configured, the wrapper still starts and exposes only the read-onlydomscan_mcp_statustool. This lets MCP registries inspect and validate the server without granting access to domain-intelligence operations.
docker build -t domscan-mcp . docker run --rm -i -e DOMSCAN_API_KEY=your-api-key domscan-mcp
The local wrapper uses API-key authentication. Clients that support remote Streamable HTTP and OAuth should continue connecting directly tohttps://domscan.net/mcp; OAuth remains the recommended option for those clients.
The server exposes domain-intelligence tools across these areas:
- DNS: record lookups (A, AAAA, MX, TXT, NS, CNAME, CAA), full record dumps, propagation checks, DNS security.
- WHOIS / RDAP: registration data, WHOIS history, reverse WHOIS, RDAP.
- SSL/TLS: certificate audit, chain inspection, grade, expiry checks, deep scan, certificate search.
- Subdomains: subdomain enumeration and discovery.
- Availability and valuation: domain availability (single and bulk), appraisal, name suggestions.
- Email security: SPF, DKIM, DMARC validation and DNSSEC posture.
- Brand protection: typosquatting detection, brand monitors and scans.
- Infrastructure: IP lookup, hosting detection, ASN, technology/stack detection, MAC vendor lookup.
See theDomScan API documentationandMCP setup guide.
MCP 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.
