I have the same issue. variable references like
${workspaceFolder}cannot be resolved strangely in this case. I have the same issue with relative paths. The only workaround that works for me is using an absolute path which isn't ideal since I prefer to have the MCP servers configured in the user settings and therefore multiple projects share the same file.@KingOfTac, have you found a solution?

#1600, #1481 and #1018 seem to be related or actual the same issue.

${workspaceFolder}is a client-side variable; the server receives whatever string the client puts in the environment. VS Code now substitutes it inmcp.json, and Claude Desktop does not support variables at all. The relative-path behaviour mentioned in the follow-up is #692, which #4327 fixes. Closing this one.
