Stateless MCP revives interest – Simon Willison launches mcp-explorer and datasette-mcp
Anthropic rolled out MCP 2.0 (stateless Model Context Protocol) on July 28, 2026, marking the biggest change to the specification since launch. The new version simplifies implementation by replacing two HTTP requests with one, and Willison has built three new MCP tools in response: mcp-explorer (a CLI tool for testing MCP servers) and datasette-mcp (a plugin that provides SQL access to Datasette instances).
WHY IT MATTERS
Stateless MCP makes the protocol safer and simpler to implement compared to earlier agent approaches with shell access, and opens the door for even smaller models to run MCP tools effectively.
