Fixes #10 - Add support for direct installation from GitHub using uvx. Key changes: - Relaxed Python version requirement to >=3.10 for broader compatibility - Updated README with uvx installation instructions and MCP configuration - Added Make targets `test-uvx` and `test-uvx-mcp` for testing uvx functionality - Updated MCP configuration examples in Makefile comments to use uvx from GitHub - Verified uvx installation works: `uvx --from git+https://github.com/ber-data/bertron-mcp.git bertron-mcp` Users can now install and run bertron-mcp directly from GitHub without cloning the repository or waiting for PyPI publication. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Update Python requirement to >=3.12.9 to match bertron-client dependency - Add missing build-system section with hatchling configuration - Add hatch.metadata.allow-direct-references for git dependencies - Fixes 'make all' pipeline and enables proper packaging
Updates package lock file with correct dependency resolution after fixing Python version requirement.
Successfully merged main branch improvements while preserving uvx functionality: - Combined comprehensive README from main with uvx installation options - Maintained working Python version requirement (>=3.12.19,<3.14) from main - Added uvx test targets alongside existing test infrastructure - Preserved both uv run (local dev) and uvx (GitHub) usage patterns - Removed autogenerated _version.py file (now properly gitignored) Both installation methods now available: - uvx --from git+https://github.com/ber-data/bertron-mcp.git bertron-mcp (GitHub) - uv run python src/bertron_mcp/main.py (local development)
Removed corrupted lock file with merge conflicts and regenerated from scratch. All tests passing, dependencies resolved correctly.

- Removed Git merge conflict markers (<<<<<<< HEAD, =======, >>>>>>> main) - Kept the enhanced README content with comprehensive documentation - Maintained all API limits, constraints, and usage examples - Preserved MCP integration instructions and testing documentation 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Added back the Quick Start section that was accidentally removed during merge conflict resolution - Preserves important uvx installation instructions for direct GitHub usage - Maintains user-friendly installation documentation - Quick Start provides immediate value for users wanting to try bertron-mcp 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
- Removed defensive try/except patterns that were masking real issues - Made tests more assertive about expected return types and behaviors - Kept try/except only where legitimately needed (regex errors) - Differentiated between functions that should always work vs those that may return None - Improved test clarity by removing generic exception handling - Functions now expected to return proper types or fail clearly Key changes: - health_check() must return dict (not None) - search functions must return QueryResponse (not None) - entity_lookup() may return None for invalid IDs (documented behavior) - Invalid search parameters should return empty QueryResponse, not None - Constraint reporting tests now assertively verify metadata presence This makes tests more reliable for catching real bugs while maintaining appropriate handling of legitimate edge cases. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
Addresses API 400 errors discovered when removing defensive try/except blocks in tests. This change implements robust regex validation and eliminates None returns to provide consistent, predictable function behavior. ## Key Changes ### Enhanced search_by_name() Function (src/bertron_mcp/main.py) - **Regex Validation**: Added upfront regex pattern validation using re.compile() to catch invalid patterns before API calls, preventing 400 Bad Request errors - **Eliminated None Returns**: Changed return type from `QueryResponse | None` to `QueryResponse` - function now always returns a valid response object - **Improved Error Handling**: Invalid regex patterns return empty QueryResponse with descriptive constraint metadata instead of hitting API - **Unified Constraint Reporting**: Standardized constraint metadata structure to match other search functions with proper nested format - **API Error Recovery**: Network/API errors now return empty QueryResponse with error details instead of None ### Test Suite Improvements - **Removed Defensive Assertions**: Updated all search_by_name tests to expect QueryResponse objects instead of allowing None values - **Fixed Constraint Validation**: Updated limit enforcement tests to check proper nested constraint structure (constraints["limit"]["requested"]) - **Enhanced Error Coverage**: Tests now properly validate regex error handling without masking real API issues ### Files Modified - **src/bertron_mcp/main.py**: Core search_by_name() function improvements - **tests/test_api.py**: 4 test functions updated for consistent return types - **tests/test_integration.py**: Removed conditional None checks - **tests/test_error_handling.py**: Minor formatting improvements - **tests/test_mcp_protocol.py**: Formatting consistency ## Problem Solved Previously, invalid regex patterns like "[", "(?P<", "*", "(?" would cause: 1. BERtron API to return 400 Bad Request errors 2. search_by_name() to return None instead of meaningful responses 3. Tests to hide real API issues with defensive try/catch blocks Now invalid patterns are validated locally and return structured error responses, while all functions maintain consistent return types that align with the "honestly i don't even like the allowance for none" feedback. ## Testing All 69 tests pass, including the previously failing regex validation tests. The fix enables more assertive testing that catches real API issues while providing better user experience through consistent error reporting. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
