Month: 2026-03 | Repository: modelcontextprotocol/typescript-sdk. Key deliverable: Prompt Metadata Support in registerPrompt. This feature adds a _meta field to prompts, enabling metadata such as author, version, and category to be attached for improved management, governance, and discoverability. The change lays the groundwork for metadata-driven workflows and easier prompt auditing.

July 2025: Delivered a feature in modelcontextprotocol/modelcontextprotocol to support default values for all primitive types in elicitation schemas and align client-side validation accordingly. Key deliverables include defaults in schemas, pre-populated inputs, and consistent handling across clients, with documentation updated to reflect feature usage and client expectations. No major bugs fixed this month; minor refinements were made to enforce a single, consistent client behavior path based on feedback. Business impact includes faster form completion, reduced user errors, improved data quality, and clearer API contracts. Technical impact demonstrates API/schema design maturity, client-side validation alignment, cross-client consistency, and thorough documentation. Technologies/skills demonstrated include schema design, client-side validation, cross-client consistency, documentation, and Git-based collaboration.
