Stateless MCP renews interest in the protocol
Simon Willison
EDITOR BRIEF
The article says the new stateless version of MCP is the biggest change since the protocol began and has renewed the author’s interest in it. MCP is a standard for exposing tools to LLM-based agent systems, and the newer design is simpler to implement for both clients and servers. The author also says this led to building three MCP-related projects in one week.
INSIGHTS
For learners, this shows how protocol design affects both safety and ease of use in AI tooling. A good next step is to compare stateful versus stateless request flows and try building a tiny MCP tool server.
