FastDomainCheck

A Model Context Protocol implementation for checking domain name registration status in bulk.

- FastDomainCheck Online Service- Check domain registration status in bulk online
- MCP Server Documentation- Detailed project documentation and technical specifications

{ "domains": ["example.com", "test.com"] }

- domains: Array of strings containing domain names to check

- Maximum length of 255 characters per domain
- Maximum 50 domains per request
- No empty domain names allowed

{ "results": { "example.com": { "registered": true }, "test.com": { "registered": false } } }

- results: Object with domain names as keys and check results as values

- registered: Boolean

- true: Domain is registered
- false: Domain is available

The tool will return an error in the following cases:
- Empty domains list
- More than 50 domains in request
- Empty domain name
- Domain name exceeding 255 characters
- Result serialization failure

{ "error": "Error: domains list cannot be empty" }

{ "domains": ["example.com", "test123456.com"] }

{ "results": { "example.com": { "registered": true }, "test123456.com": { "registered": false } } }

- Domain checks are executed sequentially, taking approximately 0.3-1 second per domain
- Maximum 50 domains per request to prevent resource exhaustion
- WHOIS query timeout set to 10 seconds
- DNS query fallback when WHOIS query fails
- Input Validation: Comprehensive validation before processing
- Dual Verification: WHOIS primary, DNS fallback
- Timeout Management: Reasonable timeouts for all network operations
- Detailed Error Messages: Clear error descriptions for troubleshooting
