How do I check if a MAC address is valid?

You can use the `validate_mac_address` tool to check the syntax and receive a normalized version of the address.

Can I find out who manufactured a device?

Yes, the `get_vendor_from_oui` tool extracts the Organizationally Unique Identifier to identify the registered vendor.

What is the difference between unicast and multicast in this tool?

The `analyze_mac_properties` tool identifies if an address is unicast (one-to-one) or multicast (one-to-many) based on the bit patterns in the first byte.

This MCP server provides precise tools for network address analysis. Use validate_mac_address to verify syntax and normalize strings. Use analyze_mac_properties to determine if an address is unicast or multicast, and whether it is universally or locally administered. Finally, use get_vendor_from_oui to identify the manufacturer associated with the address prefix.
