Authenticate MCP servers from your shell with claude mcp login, get a response to shell mode command output with the ! prefix, and resume a conversation from before /clear with /rewind.
New `claude mcp login /mcp menu. `claude mcp login` runs the server's OAuth flow directly, and `claude mcp logout` clears the stored credentials.
Run the OAuth flow for a configured server without opening a session:
claude mcp login sentry
Commands you run with the ! prefix now get a response from Claude once the output lands in the transcript, so you can run ! npm test and get an explanation of the failures without a second prompt. The response costs the same as sending a normal prompt. To keep the earlier behavior, where the output is added to context without a response, set respondToBashCommands to false in settings.json.
Run a command and get a response to its output:
> ! npm test
