Model Context Protocol

Earendil has published a post titled 'You Said No MCP', which is drawing discussion on Hacker News. MCP refers to the Model Context Protocol, an emerging standard for connecting AI models to external tools and data sources. The title suggests a story about customers or teams rejecting MCP adoption, a debate that resonates as companies weigh how much AI infrastructure to integrate into their products.

The modelcontextprotocol organisation's servers repository, written in TypeScript, provides reference implementations of Model Context Protocol servers. The open-source project lets developers connect AI assistants like Claude to data sources and tools such as file systems, databases and third-party services. It is drawing attention among developers working on AI integrations and agentic applications.

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.

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.
