Security Report
7.2
Moderate7.2Low RiskA well-structured MCP server for audio file analysis with appropriate authentication and reasonable permission scoping. The server properly validates API keys, implements input validation with Zod, and uses safe file I/O patterns. Minor code quality observations around error handling and filesystem access permissions do not materially impact security posture. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity). Package verification found 1 issue.

TrackTag MCP Server
Let AI agents (Claude Desktop, Claude Code, Cursor, and any MCP-capable client) analyze music with TrackTag: drop an MP3 into your agent, say "analyze this track", and get BPM, key, genres, moods, instruments, energy and 35+ metadata fields back.
Runs locally over stdio — nothing is hosted, the server only lives while your agent app is open. Analyses are billed from your TrackTag credit balance (1 credit per track with the core model, 2 with ultra); failed analyses are refunded automatically.
Setup
- Get an API key: tracktag.me/studio → API & MCP → Create key (
tt_live_…). - Add the server to your agent's MCP config:
Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json):
{
"mcpServers": {
"tracktag": {
"command": "npx",
"args": ["-y", "tracktag-mcp"],
"env": { "TRACKTAG_API_KEY": "tt_live_YOUR_KEY" }
}
}
}
Claude Code:
claude mcp add tracktag -e TRACKTAG_API_KEY=tt_live_YOUR_KEY -- npx -y tracktag-mcp
Cursor (~/.cursor/mcp.json): same JSON block as Claude Desktop.
