Install PlatformIO in Claude Code, Cursor or VS Code

Add to Cursor

What the publisher says

From the PlatformIO repository's README, as published. We do not edit it. Read it on GitHub

platformio.mcp

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.

Python native · no Node · one line to install · works with Claude Code, Claude Desktop, Cursor, Codex, Windsurf, Cline

⚡ 60-second install

You need uv (curl -LsSf https://astral.sh/uv/install.sh | sh). Then:

uvx platformio.mcp install --claude-code      # or --cursor  --claude-desktop  --codex  --windsurf

No PlatformIO on this machine? Add --with-platformio and the server brings PlatformIO Core along. Optional extras: platformio.mcp[coredump] adds the ESP32 core-dump analyzer, platformio.mcp[power] adds the Nordic PPK2 driver.

Any other MCP client (Cline, Zed, Continue, ...)

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

Use "args": ["platformio.mcp[platformio]"] to bundle PlatformIO Core.

As a plugin (Claude Code, Cursor: server + a skill that teaches the loop)

The repo follows the Open Plugins layout: .mcp.json, skills/platformio/SKILL.md, rules/platformio.mdc, plugin.json.

claude plugin marketplace add powerdragonfire/platformio.mcp   # Claude Code
claude plugin install platformio@platformio.mcp

Already have PlatformIO?

The server finds platformio / pio on your PATH or in ~/.platformio/penv. Override with PLATFORMIOMCPPIO=/path/to/pio. Run uvx platformio.mcp doctor to see what the agent will see.

🎬 What it looks like

You: flash the view env and make sure it boots.

Agent → pioflashand_verify(env="view", expect="setup done")

FAIL: firmware flashed but the boot log matched the failure pattern:

'Guru Meditation Error: Core 1 panic'ed (LoadProhibited)'.

Cause: LoadProhibited. 3/3 addresses resolved:

DisplayTask::run() (displaytask.cpp:22) <- DisplayTask::run() (displaytask.cpp:23) <- vPortTaskWrapper (port.c:143)

Agent: null pointer on line 22 of displaytask.cpp, tft is used before begin(). Fixing, rebuilding, flashing again.

PASS: flashed env view in 14.2s and saw 'setup done' on /dev/cu.usbserial-0001 after 2.1s of boot output.

No 40 KB build logs in the context window. No human reading the serial monitor. The agent gets a verdict, a file and a line.

🔁 The loop the agent runs

flowchart LR
    A[pio_project_envs] --> B[edit code]
    B --> C[pio_build]
    C -- errors with file:line --> B
    C -- ok --> D[pio_flash_and_verify]
    D -- PASS --> E([done])
