One issue i saw related to scopes is the offline_access one that causes frequent reauthenticate request from the client. for example codex has this bug (https://github.com/openai/codex/issues/20503). many servers solve this with some workarounds or increasing the token life. In v2 of mcp-use coming end of the month there should be a builtin way to deal with buggy clients so the server remains connected.

with our SDK we provide many adapters to popular authentication providers which basically provision oauth on your server in one line of code, here the docs https://docs.mcp-use.com/typescript/server/authentication/in...

also we ship templates for you to get started https://manufact.com/templates

You may want to have a look at Skybridge, a TypeScript framework designed to build MCP servers and MCP Apps, with a recent emphasis on making authentication easy.

Can you get into the specifics of the problems you currently experience with MCP? I'd love to learn more.
