ProbeCodex turns Claude, Cursor, and any MCP client into a hands-on ARM Cortex-M debugger. GDB, FreeRTOS, flash, and trace — all locally, on your hardware.
Works with what you already use
What you get
Everything your AI assistant needs to drive a debug probe — exposed as MCP tools it can call directly.
Full GDB/MI integration. Step, breakpoint, watch, and disassemble any ARM Cortex-M target through your AI assistant.
Real-time task lists, queue inspection, heap statistics, and stack-watermark analysis — without firmware modifications.
Automated hex/binary flashing with CRC verification, incremental updates, and mass-erase across all major probe types.
ITM/SWO and J-Link RTT capture streamed live to your AI assistant for log-driven debugging without serial cables.
The difference
ProbeCodex asks why, with full project context.
A breakpoint is just a memory address. The AI assistant standing behind it can correlate the address with the source code, RTOS task state, recent commit history, and the SVD-defined peripheral that owns that register. That's the debugger you actually want.
vs raw GDB
Your AI assistant knows the symbol map, peripheral SVDs, RTOS state, and trace history. It reasons about the target — not just prints registers.
vs vendor IDEs
STM32CubeIDE, MCUXpresso, e² studio, NuEclipse — every vendor ships their own. ProbeCodex runs in your existing AI assistant and speaks to every probe through OpenOCD/PyOCD/J-Link.
vs cloud debuggers
The MCP server runs locally. Probe traffic, symbol tables, and trace logs stay on your hardware. No SaaS dashboards, no telemetry of your IP.

Free beta · waitlist
Drop your email below to join the waitlist. We'll send you a magic sign-in link plus instructions: after you sign in, just ask your coding agent (with the ProbeCodex MCP installed) to renew or get a free beta license. Use the same email address you join with, and tell it which tier you want — basic, pro, team, or enterprise. Run /mcp in Claude Code (or any MCP-compatible agent) to confirm the ProbeCodex MCP binary you downloaded is loaded.
Download the free beta — auto-renewing 7-day licenses, no credit card. Your AI assistant becomes a Cortex-M debugger in minutes.
