Validation Utilities

Validate Mac

Validates MAC address format across common notations including colon-separated (AA:BB:CC:DD:EE:FF), hyphen-separated, and dot-separated variants. Use via MCP in Cursor or Windsurf for network tooling, or call GET /v1/validate/mac directly. Returns boolean validation with format details — essential for network configuration scripts and device management workflows.

API Endpoint

GET /v1/validate/mac

Code Examples

curl "https://tinyfn.io/v1/validate/mac" \
  -H "X-API-Key: YOUR_API_KEY"
const response = await fetch('https://tinyfn.io/v1/validate/mac', {
  headers: { 'X-API-Key': 'YOUR_API_KEY' }
});
const data = await response.json();
console.log(data);
import requests

response = requests.get('https://tinyfn.io/v1/validate/mac',
    headers={'X-API-Key': 'YOUR_API_KEY'})
data = response.json()
print(data)

FAQ

What MAC address formats does the validator accept?

Accepts colon-separated (AA:BB:CC:DD:EE:FF), hyphen-separated (AA-BB-CC-DD-EE-FF), dot-separated (AABB.CCDD.EEFF), and plain hex formats. Case-insensitive for hex digits.

How do I validate MAC addresses in my MCP-enabled editor?

Call the validate_mac tool from Cursor, Windsurf, or other MCP clients. Pass the MAC string as parameter — the tool returns validation status and detected format type.

Does it validate both EUI-48 and EUI-64 addresses?

Validates standard 48-bit MAC addresses (6 octets). For 64-bit EUI addresses, use a dedicated EUI-64 validator instead.

What happens with broadcast or multicast MAC addresses?

Validates format regardless of address type — broadcast (FF:FF:FF:FF:FF:FF) and multicast addresses pass if properly formatted.

Can I validate MAC addresses from network interface output?

Yes, handles common formats from ifconfig, ip link, and network device configurations. Strips whitespace and validates the extracted MAC string.
