An ESP32 Bluetooth Mouse Jiggler With an On-Board MCP Server Exposing 28 Tools
nurge86 · reddit · 2026-10-30
Built to stop Microsoft Teams marking the author away during calls, Jiggler is an ESP32 acting as a Bluetooth mouse, powered over USB. The interesting part: an MCP server runs on the board itself alongside a web dashboard and REST API, exposing 28 tools for timed sessions, schedules, and Bluetooth management — no separate host server needed. It integrates with Home Assistant, and the code plus build instructions are public, so anyone can replicate it free with their own ESP32.
