MCP Integration in Claude Code
Last reviewed
Correct answer: B. It connects exactly once, using the definition that comes from the highest-precedence source.
Explanation
The principle — Duplication is resolved before connection, not after it.
Why the key is correct — When the same server is defined in more than one place, Claude Code connects to it once, using the definition from the highest-precedence source. You never end up with two of anything.
Why the others are wrong — There is no second connection and no second tool set. Recency plays no part in the decision. And user scope is the lowest of the three scopes in the order, not the highest.
Remember this — One name, one connection, and scope decides which definition supplies it.
