Show HN: MCP for Your Mac Hardware

Category: observability

Tags: macos, hardware-monitoring, mcp, swift, apple-silicon

Score: 6.8/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 6)

MacMonitor is a native macOS menu-bar app that reads Apple Silicon hardware sensors (SMC, IOReport, HID, NVMe SMART) to show live temperature, CPU/GPU usage, fan speed, and power, with history and alerts. It also exposes an MCP server so AI agents like Claude and Codex can query the same sensor data, filling a gap between hardware observability and AI tooling. Notable for being read-only, privacy-preserving, and well-documented despite being a small solo project.

Target audience: macOS power users, developers using AI agents, and Apple Silicon owners troubleshooting fan/thermal issues
