Unclear It is not known what the other hint says or which servers get it.
What
When an MCP server needs you to sign in again, Claude Code shows a message saying so. MCP servers are outside programs that give Claude Code extra tools. The message used to end with "(run /mcp to re-authenticate)" every time.
It now looks at that server's settings first. For some servers, it shows a different hint in its place.
Why
The advice you get on how to sign back in to an MCP server can now differ from server to server.

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
Added since
A small documentation edit on MCP, plugins, skills, and hooks touched a line naming /mcp after this was published.
| `.mcp.json` | MCP servers bundled with this plugin. A JSON object keyed by server name: `{"mcpServers": {"<name>": {"type": "http", "url": "...", "oauth": true}}}`. A remote entry uses `type` (`http` or `sse`), not `transport`, and suppo…third-party/claude-desktop/extensions see the edit
Confirmed since
Anthropic's documentation has since written up /mcp, on Claude Code changelog.
