Worked on the awslabs/mcp repository to enhance tool naming consistency within the Billing Cost Management MCP, focusing on improving discoverability and reducing misconfigurations. The primary contribution involved renaming three core tools and propagating these changes across Markdown documentation, server configurations, and tool definitions. This standardization effort established a clear naming convention baseline, supporting automation reliability and easing onboarding for future contributors. Leveraged skills in AWS Services, backend development, and code refactoring to ensure seamless integration of the updates. No major bugs were reported during this period, as the work concentrated on technical clarity and maintainability rather than feature expansion.
