Platform IO MCP Server

Give your AI coding agent hands on real hardware. An MCP server for PlatformIO : build, flash (serial or OTA), watch serial, run tests, decode crashes and core dumps, check partition tables, watch heap and power, debug over GDB, shrink firmware. It runs locally over stdio via the published package.

People who work with embedded, esp32 and platformio and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Platform IO

Claude Code

claude mcp add powerdragonfire-platformio.mcp -- uvx platformio.mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "powerdragonfire-platformio.mcp": {
      "command": "uvx",
      "args": [
        "platformio.mcp"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

license MIT - declared in the repository

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

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