ar: Agent Receipts is an open protocol for generating cryptographically signed audit trails for AI agent actions. It provides SDKs in Go, TypeScript, and Python, plus an MCP proxy that intercepts and signs agent tool calls using Ed25519 signatures. The receipts can be verified independently, enabling accountability and traceability in agentic systems.; beatos: BeatOS is a local-first desktop application for music producers that organizes beat libraries and automates metadata tagging and multi-platform distribution through an AI co-pilot. It includes a built-in MCP server for Claude Code and Claude Desktop integration, enabling natural language control over catalog management, BPM detection, and publishing to beat marketplaces.
