Tried this, no joy. I created a CORE API key from my workspace->API page, configured MCP with Claude Desktop, I get this: "You didn't provide an API key...You can obtain an API key from https://platform.openai.com/account/api-keys"
Other memory MCP servers do not require access to OpenAI - and not even sure why I would want any of my data going there when I use a paid Claude subscription.
I like the idea here, but doesn't seem very usable.
