BVCampos introduced Canvas on Hacker News as a “Show HN” project for multiplayer HTML with an MCP-first design. The linked GitHub repository is the primary technical artifact, but the available announcement provides few implementation details. At the time of the supplied record, the Hacker News post had a score of 3 and no comments, so claims about architecture, collaboration semantics, MCP usage, performance, or production readiness should be verified directly in the repository rather than inferred from the title.
