- Removed quotes from 'claude mcp add arduino uvx mcp-arduino'
- Claude MCP expects space-separated arguments, not quoted strings
- Ensures users can properly add the server to Claude Desktop
- Added --version and -V flag handling to main() function
- Displays package version and exits cleanly
- Fallback version if importlib.metadata fails
- Enhances CLI usability for version checking
- Fixed CircularBuffer → CircularSerialBuffer import
- Fixed ClientCapabilities → ClientCapabilitiesInfo import
- Fixed ClientDebug → ClientDebugInfo import
- Fixed SerialManager → SerialConnectionManager import
- Bumped version to 2025.09.27.2
These import errors prevented the published package from starting.
All components now use their actual class names.
BREAKING CHANGES:
- Package renamed from mcp-arduino-server to mcp-arduino
- Command changed to 'mcp-arduino' (was 'mcp-arduino-server')
- Repository moved to git.supported.systems/MCP/mcp-arduino
NEW FEATURES:
✨ Smart client capability detection and dual-mode sampling support
✨ Intelligent WireViz templates with component-specific circuits (LED, motor, sensor, button, display)
✨ Client debug tools for MCP capability inspection
✨ Enhanced error handling with progressive enhancement patterns
IMPROVEMENTS:
🧹 Major repository cleanup - removed 14+ experimental files and tests
📝 Consolidated and reorganized documentation
🐛 Fixed import issues and applied comprehensive linting with ruff
📦 Updated author information to Ryan Malloy (ryan@supported.systems)
🔧 Fixed package version references in startup code
TECHNICAL DETAILS:
- Added dual-mode WireViz: AI generation for sampling clients, smart templates for others
- Implemented client capability detection via MCP handshake inspection
- Created progressive enhancement pattern for universal MCP client compatibility
- Organized test files into proper structure (tests/examples/)
- Applied comprehensive code formatting and lint fixes
The server now provides excellent functionality for ALL MCP clients regardless
of their sampling capabilities, while preserving advanced features for clients
that support them.
