Along these lines, I’m working on a tool called Spotless[0] that takes a more HTTP proxy-based approach to make statefulness something the agent doesn’t have to worry about. It directly reads & writes to the messages array going to and from Anthropic, so you don’t have to rely on the agent calling an MCP or using a skill. Still buggy and early, but it’s definitely a very interesting way of working with agents.
