Overview

AI-generated overview

Lets an assistant look up the hardware vendor behind a MAC address using the MAC Vendors database.

What you can do
This local MCP server exposes a MAC address lookup capability. Given a MAC address, it queries the MAC Vendors database and returns the registered vendor or manufacturer name. It is a small, single-purpose utility with no other tools described.
When to use it
Useful when an assistant needs to identify the manufacturer of a network device from its MAC address, for example during network inventory, device troubleshooting, or interpreting logs and scan results.
Requirements
Runs as a local process on the user's machine via the npm package mac-lookup-mcp over stdio. Requires Node.js and network access to reach the MAC Vendors database. No API key, environment variables, or headers are declared.
Before you install
Lookups send the MAC address being queried to the external MAC Vendors service, so MAC addresses are shared with a third party. MAC addresses can be considered device-identifying information; avoid submitting addresses you do not want disclosed externally.

Installation

In SourceWeft

  1. Open Mac Lookup Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
