Webcam allows Claude Desktop (or other MCP Clients) to access live webcam feeds and capture screenshots. It exposes 'capture' and 'screenshot' tools, as well as a 'current view from the webcam' resource. This enables use cases such as asking Claude to describe the current view from your webcam or take a screenshot of a specific browser window. It serves as a useful demonstration of how to build local, interactive MCP Servers with user interfaces and live resource serving.
