Project description

Overview This project delivers an MCP (Model Context Protocol)–oriented firmware for the Raspberry Pi Pico W. It exposes device capabilities as JSON-RPC tools so an IDE agent (e.g., Copilot Chat) can remotely perform actions like toggling the onboard LED. The repo includes PICO-SDK build instructions and a WireGuard import script to scaffold a secure tunnel around MCP traffic for remote operation scenarios. (GitHub) Original Language & Author The source is written in English and maintained by @h7ga40. The README outlines an agent-driven workflow (VS Code Copilot Chat) that invokes the…
