• Bug fix (non-breaking change that fixes an issue)
• New feature (non-breaking change that adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update
• Refactoring (no functional changes)
• Test updates
• Chore (dependencies, tooling, etc.)

Linting Results

$ make lint
go tool golangci-lint run --timeout 2m
# No issues found - all checks passed

Summary:

• ✅ All unit tests passing (50+ test cases across all command packages)
• ✅ Server functionality tests passing (12 subtests validating MCP client and tool filtering)
• ✅ All linting checks passing with no issues
• ✅ Version parameter properly propagated through entire command chain

Checklist

• Code follows project style guidelines
• Self-review completed
• Tests added/updated as needed
• Documentation updated as needed
• All tests pass locally
• No breaking changes (or documented if necessary)

Breaking Changes

None - this is an internal refactor that doesn't affect the external API.

Additional Context

This change ensures that the server version is dynamically set from the build version rather than being hardcoded, allowing for proper version tracking in MCP server responses.
