Stateless MCP Revives Interest, Inspires mcp-explorer and datasette-mcp

Simon Willison reports that the new Stateless MCP specification, rolled out on July 28, 2026, has rekindled his interest in the Model Context Protocol. He highlights the simplifications it brings and shares three new projects he built: mcp-explorer, datasette-mcp, and llm-mcp-client. Willison argues that MCP tools are safer and easier to audit than giving agents arbitrary shell and curl access.
On Tuesday, July 28, 2026, the Stateless MCP specification (MCP 2.0) was rolled out, marking the most significant change to the Model Context Protocol since its launch. Simon Willison, who had previously moved away from MCP in favor of Skills and agent harnesses with terminal access, now sees renewed value in MCP because it offers easier auditing and control, and works well with smaller models. The new stateless version eliminates the need for session initialization requests and server-side state, simplifying both client and server implementations. Inspired by this, Willison built three tools: mcp-explorer, a Python CLI for probing MCP servers; datasette-mcp, a Datasette plugin that adds an MCP endpoint; and llm-mcp-client, an alpha plugin for his LLM tool. He successfully connected datasette-mcp to ChatGPT and Claude, and demonstrated querying his blog's database with SQL. Willison notes that while MCP has prompt injection security concerns, it is still safer than granting agents arbitrary shell and curl access in open network environments.
