An MCP server that allows an agent to find the vendor that a network interface MAC address is registered under and other information about the block like it's registered country, the registry type it is in, how many addresses are in it's block and a link with more information. Stateless MCP 2026-07-28 version support only.
Scored across 1 tool
With only one tool, there is no possibility of misselection or overlapping purpose. The tool's function is clearly defined and distinct.
A single tool named 'lookup' follows a simple, predictable convention. There are no mixed styles or inconsistent patterns to evaluate.
For a narrow MAC address lookup utility, one tool is sufficient and well-scoped. However, it is below the typical 3-15 range, making the server feel slightly thin.
The tool fully covers the apparent domain of resolving MAC addresses and OUI prefixes to registered organizations. No obvious gaps exist for the stated purpose.
Resolve a MAC address or OUI prefix to its registered organization using longest-prefix match across the MA-L, MA-M, MA-S, IAB, and CID registries. Reports the block type, address count, registration country, and a link to the full record page. Randomized and locally administered addresses usually have no registered organization.
Inputs: mac (required). Returns: url, query, prefix, country, +5 more
