A new essay titled "You Said No MCP" is drawing heavy attention on Hacker News, ranking near the top of the site with close to 600 upvotes. The piece, published by Earendil, weighs in on the debate around the Model Context Protocol, the emerging standard for connecting AI assistants to external tools and data. Commenters are actively debating its arguments about how and whether developers should adopt MCP.

Earendil has published a new post explaining why its Pi.dev product does not support MCP, the Model Context Protocol that has become a common standard for connecting AI assistants to external tools. The piece defends the decision to skip the protocol, and the argument is drawing attention and debate among developers following the discussion.

Earendil's Pi, an AI coding assistant, previously declined to support the Model Context Protocol on its own website but is now integrating it into its core. The shift has prompted discussion of what MCP is and how the assistant's position on the open protocol changed, drawing interest from developers following AI tooling standards.
