10451045A server you've added in Claude Code takes [precedence](#scope-hierarchy-and-precedence) over a claude.ai connector that points at the same URL. When this happens, `/mcp` lists the connector as hidden and shows how to remove the duplicate if you'd rather use the connector.

1047Some Anthropic-hosted connectors, such as Microsoft 365, Gmail, and Google Calendar, don't support local OAuth from Claude Code because the upstream identity provider only accepts the redirect URL that claude.ai registered. Authenticating one of these hosts in `/mcp` shows a message directing you to connect it at Settings → Connectors on claude.ai instead. Once connected there, the connector appears in Claude Code automatically.
1047Some Anthropic-hosted connectors, such as Microsoft 365, Gmail, and Google Calendar, don't support local OAuth from Claude Code because the upstream identity provider only accepts the redirect URL that claude.ai registered. When a server you added with `claude mcp add` or in `.mcp.json` points at one of these hosts and you sign in to it from `/mcp` or with `claude mcp login`, Claude Code shows [`is Anthropic-hosted and doesn't support local OAuth`](/docs/en/errors#anthropic-hosted-and-doesnt-support-local-oauth), directing you to connect the service at [claude.ai/customize/connectors](https://claude.ai/customize/connectors) instead.
