Koskamo

webear MCP

An MCP server and browser SDK that allows AI coding assistants to capture, analyze, and describe live audio output from web applications using the Web Audio API. It provides tools to record audio clips, perform signal analysis (RMS, spectral centroid, BPM), and generate plain-English descriptions of audio characteristics directly from the browser context.
