Marcin Po delivered an Asset Metadata Retrieval Tool for the mondaycom/mcp repository, enabling asset metadata to be fetched by asset ID for enhanced asset handling in the agent toolkit. He implemented structured GraphQL queries and responses, replacing manual interfaces with generated Asset types to improve type safety and consumer ergonomics. Comprehensive end-to-end tests were added to cover both successful and failure scenarios, ensuring reliability and regression safety. Marcin also updated dependencies to align with new data contracts and maintain production stability. His work leveraged TypeScript, GraphQL, and full stack development skills to support downstream analytics and workflow automation needs.
