OpenOCD Debugger MCP Server

Debug microcontrollers directly from your AI assistant. This is an MCP server that drives OpenOCD, letting any MCP-compatible AI flash firmware, control execution, and inspect a running target - and read your variables and peripheral registers by name instead of raw addresses. It runs locally over stdio via the published package.

People connecting developer tools tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Tcl.

01 · Install OpenOCD Debugger

Claude Code

claude mcp add microhenrio-openocd-mcp -- uvx openocd-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "microhenrio-openocd-mcp": {
      "command": "uvx",
      "args": [
        "openocd-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

pypi package openocd-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.microhenrio is GitHub-verified and matches the repo owner
