STM32 GDB MCP

An MCP server that enables AI agents to debug STM32 firmware on real hardware by driving GDB with OpenOCD, ST-Link, or J-Link. It supports flashing, breakpoint management, memory and register inspection, HardFault triage, FreeRTOS analysis, and performance profiling, returning decoded structured evidence rather than raw GDB text.

Package and access

Local package with source-attributed installation metadata. Koskamo does not execute packages during review.
