I’m running basicmemory.com as a production cloud hosted memory. It has mcp/we ui/api/cli interfaces. The difference between mcp/cli/api has been discussed at length but in general mcp gives agents oauth (for clients like Claude web/chatgpt) and a “more agentic” interface that can helpfully steer the agent instead of having it thrash tokens on erroneous api calls and request formats. There are good and bad parts to both. Remote mcp is pretty good these days. The generative ui (mcp app) stuff is interesting and useful, if still immature. Use what works for you!
