Stateless MCP has recaptured my interest (and inspired mcp-explorer and datasette-mcp)
↗
Implementing MCP servers and clients becomes substantially simpler without session state to manage, and the protocol becomes a better fit for horizontally scaled deployments where sticky sessions are a burden. The change also repositions MCP as a safer, more auditable alternative to giving agents unrestricted shell access—something smaller local models can actually drive well.

Stateless MCP replaces the legacy two-request flow (initialize session, then call tool) with a single HTTP request that embeds client info in the call payload.
Removing server-side session state eliminates the need to route requests to the same backend machine, making MCP easier to scale.
MCP tools are easier to audit and control than giving an agent a shell environment, and remain usable by smaller models that run locally.
