Arduino Agent v0.5.1 — synced with upstream Arduino IDE 2.3.10. Windows x64 build, verified end-to-end.

What changed since v0.5.0

  • Arduino CLI 1.3.1 → 1.5.1 — the compile/upload engine, with newer board/core support and fixes. Ported together with its matching gRPC protocol stubs and core/config/sketches services from the upstream 2.3.10 release.
  • "Clean compile/verify" — shift+click the Verify button to force a from-scratch build.
  • Upstream fixes: modified sketches now recompile correctly in more caching scenarios; a startup error from missing CLI directory defaults is resolved.
  • Built-in examples refreshed to 1.10.3.

The embedded MCP server, AI-collaboration features, and UI are unchanged from v0.5.0.

Install & run

  1. Download Arduino-Agent-0.5.1-Windows-x64.zip below and unzip it anywhere.
  2. Run Arduino IDE.exe. This build is unsigned — click More info → Run anyway past SmartScreen.
  3. The MCP server starts on http://127.0.0.1:3847 and prints a ready-to-paste client config (with your auth token) to the console; the token is also at ~/.arduinoIDE/mcp-token.

Verified in this build

  • Both extensions typecheck against the updated gRPC protocol.
  • arduino-cli 1.5.1 compiles a sketch through the MCP arduino_compile path (gRPC daemon), returning real build output — the highest-risk part of the CLI bump, confirmed working.

Known limitations

  • Unsigned; Windows x64 only (macOS/Linux release CI still being hardened).
  • Upload and live serial need a physical board to fully exercise.
