Arduino CLI MCP

Example Use Cases

• 1

  Compile Arduino sketches and obtain build artifacts (hex path, build directory, and error diagnostics) programmatically.

• 2

  Upload compiled sketches or hex files to connected boards and manage board/platform installation via Arduino CLI commands.

• 3

  Search, install, list, and manage Arduino libraries and to start a serial monitor or diagnose compilation errors for automated troubleshooting.

Description

Arduino CLI MCP is a lightweight Model Context Protocol server that wraps the Arduino CLI so agents (e.g., VSCode extensions or LLMs) can compile sketches, upload firmware, manage platforms and libraries, and run serial monitors programmatically. It simplifies repetitive workflows with features like auto-approval for common operations and can be configured via JSON. The project is installable via pip and aims to bridge Arduino workflows with AI tools and editor integrations.
