Worked on the pydantic/pydantic-ai repository to deliver an update to the MCP Transport Documentation for the mcp-run-python tool, ensuring alignment with recent Model Context Protocol transport changes. Focused on improving clarity by refreshing MCP URLs and elaborating on usage and compatibility for Stdio, Streamable HTTP, and SSE, the documentation now enables engineers to integrate MCP transport features with reduced ambiguity. The work was completed using Markdown and emphasized precise, accessible technical writing. No bugs were addressed during this period, and the contribution centered on documentation quality, supporting smoother adoption of new transport specifications by the engineering team.
