Stateless MCP has recaptured my interest (and inspired mcp-explorer and datasette-mcp)

The Model Context Protocol, Anthropic's standard for connecting tools to LLM agents, has released version 2.0, known as Stateless MCP, which has reinvigorated developer interest, per Simon Willison's Weblog. The improvement is architectural: the new version consolidates two HTTP requests into one, eliminating server-side session management and greatly reducing implementation complexity for both clients and servers. Willison built three projects this week demonstrating the specification's new simplicity: mcp-explorer, a CLI tool for inspecting MCP servers; a Datasette plugin that exposes database queries through the MCP interface; and an LLM command-line integration. He contends that MCP provides a more secure, more auditable foundation for AI agents than granting them shell access—a distinction increasingly important as AI tooling expands.
