Embedded Debugger MCP

What it does

This MCP server connects AI assistants directly to embedded hardware. It allows an LLM to perform real-time debugging, memory inspection, and firmware flashing on ARM Cortex-M and RISC-V microcontrollers via probes like J-Link, ST-Link, and DAPLink.

Tools

• list_probes: Discover available debug probes on the system.
• connect: Connect to a specific probe and target chip.
• read_memory: Read flash or RAM with multiple data formats.
• write_memory: Write data directly to target memory.
• halt: Stop the target execution immediately.
• run: Resume target execution.
• reset: Perform hardware or software reset.
• step: Single instruction stepping for precise debugging.
• set_breakpoint: Set hardware or software breakpoints.
• clear_breakpoint: Remove existing breakpoints.
• flash_erase: Erase flash memory sectors or the entire chip.
• flash_program: Program ELF, HEX, or BIN files to the device.
• flash_verify: Verify that flash contents match the source.
• rtt_attach: Connect to Real-Time Transfer (RTT) communication.
• rtt_read: Read data from RTT up channels.
• rtt_write: Write data to RTT down channels.
