Dbgprobe Mcp Server
Turns your debug probe into an AI-accessible tool for embedded development. Connects to J-Link probes (OpenOCD and pyOCD planned) and exposes operations like flashing firmware, reading and writing memory, setting breakpoints, and controlling target execution. Useful when you're iterating on embedded code and want to skip the manual JLinkExe workflow. Load ELF symbols for address-aware debugging, attach SVD files to read peripheral registers by name, stream RTT logs, or automate multi-board test sequences. Works over stdio with Claude Code, VS Code Copilot, or any MCP client. The server maintains stateful connections, so you can flash, halt, inspect registers, and resume without reconnecting between operations.

Readme
Debug Probe MCP Server
A stateful debug probe Model Context Protocol (MCP) server for developer tooling and AI agents. Works out of the box with Claude Code, VS Code with Copilot, and any MCP-compatible runtime. Communicates over stdio and drives on-chip debug probes (J-Link first, OpenOCD and pyOCD planned) to flash, debug, and inspect embedded targets.
Example: Let Claude Code list attached J-Link probes, connect to your nRF52840, flash a new firmware, read memory, and reset the target — all conversationally.
