MCP servers asking for input

An MCP server can ask you something in the middle of a turn: a missing detail, a choice, or a sign-in to finish in the browser. This is Claude Code’s MCP elicitation (see Claude Code’s MCP docs). Claudette shows it as a card labeled Input requested, and the tab waits on you: its row says Needs your input, and a notification goes out if Claudette isn’t in front.

The card’s title is the server’s own, or tickets asks for a server called tickets. What the server says, and every field it asks for, is its text, shown as text.

A form

The card shows the server’s message and a field for each thing it asks for:

  • A text box for text and numbers.
  • A check box for a yes or no.
  • A list for a choice.

A field the server requires says (required) in its name, and defaults come filled in. Send checks each value against what the server asked for (a whole number, a range, a length, a required field) and says what’s wrong under the field, such as Required. or A whole number. When everything fits, it sends the values to the server.

Some requests ask you to finish something in the browser, such as signing in to a service.

  1. Choose Open in browser.
  2. Finish in the browser.
  3. The card closes by itself when the server says it’s done. If it doesn’t, choose Done.

Declining

Decline tells the server you won’t provide it. Dismiss cancels the request. The card then says what happened: Sent, Done, Declined or Dismissed. A request Claude Code withdrew, or one left unanswered when the session ended, says so.

From the keyboard

Ctrl/Cmd+Enter sends a form as it’s filled in, and Ctrl/Cmd+Backspace declines the request, as they allow and deny a permission card. A link has to be opened first, so only Ctrl/Cmd+Backspace applies to it.
