Stateless MCP has recaptured my interest (and inspired mcp-explorer and datasette-mcp)
Stateless MCP cuts tool calls down to a single request, which Willison says makes the protocol practical again.
Willison says the new 2026-07-28 MCP spec removes session setup and server-side session tracking, making clients and servers simpler to build and scale. He used it to build `mcp-explorer`, release a Datasette MCP plugin, and start an MCP client for his LLM tool. The Datasette plugin exposes read-only database tools over `/-/mcp`, letting agents query hosted Datasette instances. He frames MCP as easier to audit and control than giving agents a shell with open network access. Simon Willison's note
