stlink-mcp

An MCP server that allows AI coding agents to program, run, and inspect STM32 microcontroller targets via ST-LINK hardware. It drives STM32CubeCLT command line tools, reads variables and peripheral registers from ELF and SVD files without stopping the program, and provides detailed verification status for every operation to ensure the agent receives accurate hardware feedback.
