Hideya contributed to the dandavison/modelcontextprotocol-modelcontextprotocol repository by addressing a stability issue in the Quickstart onboarding process. Focusing on documentation written in Markdown, Hideya resolved a bug where the MCP dependency installation command could fail due to improper shell interpretation. By updating the Quickstart guide to wrap mcp[cli] in quotes within the uv add command, Hideya ensured that the package would be reliably added to the virtual environment. This change reduced onboarding friction and made environment provisioning more deterministic. The work demonstrated attention to detail in documentation and command-line tooling, though it was limited in scope to a single bug fix.
