Stateless MCP has recaptured my interest (and inspired mcp-explorer and datasette-mcp)
Tuesday was Stateless MCP day - the rollout of MCP 2.0, or the 2026-07-28 Model Context Protocol specification to use the more formal but less memorable name. This is the most significant change to the MCP spec since it first launched, and has also served to reignite my personal interest in the protocol. For background: MCP is the Model Context Protocol, which describes a standard way to expose…
Tuesday marked the launch of Stateless MCP version 2.0, a significant update to the Model Context Protocol (MCP) specification. MCP, introduced by Anthropic in November 2024, provides a standard method for incorporating new tools into LLM-powered agent frameworks. The new stateless MCP specification simplifies the implementation of both clients and servers, while decreasing complexity compared to the older stateful MCP version.
This change has reignited interest in the protocol, leading to the development of mcp-explorer, a stateless Python CLI tool, and datasette-mcp, a Datasette plugin that adds an /-/mcp endpoint to any Datasette instance. These projects enable the execution of SQL queries against hosted Datasette instances, enhancing the capabilities of LLM-powered agents.
