MCP Integration in Claude Code
Last reviewed
Correct answer: A. Only you, and only in the project where it was added, because local scope is both narrow and private.
Explanation
The principle — A scope answers two questions at once: who can see the server, and in which projects.
Why the key is correct — A local-scoped server loads only in the project where you added it and stays private to you. Both limits apply together, which is what makes local scope the safest place for anything holding a personal credential.
Why the others are wrong — Other accounts on the machine cannot see it, because the entry lives in your own home directory. It does not follow you into your other projects, which is user scope's behaviour. And nobody who clones the repository gets it, because it was never written into the repository.
Remember this — Local scope is narrow twice over: one person, one project.
