@followed by the MCP server name and your instructions, e.g., "@H-ear MCP Serverclassify the bird species in this recording"
That's it! The server will respond to your query, and you can continue using it as needed.

H-ear MCP Server
AI-powered sound classification for Claude. Identify sounds, detect noise events, and classify audio across 7,000+ sound classes — from urban noise to bird species.
H-ear connects Claude to the H-ear World audio classification API via the Model Context Protocol.
Quick Start
npx @h-ear/mcp-server --key YOUR_API_KEYThat's it. Claude now has 14 tools (classification, account, webhooks), a live status resource, and a guided classification prompt.
