# Elicitation

> Handle interactive user input requests from MCP servers

Servers can ask the client for user input mid-tool-call via `elicitation/create`. Two modes:

* **Form** — structured fields with a JSON schema
* **URL** — redirect the user to an external page (required for credentials/OAuth)

## Setup

```typescript theme={null}
import {
  acceptWithDefaults,
  MCPClient,
  type OnElicitationCallback,
} from "@mcp-use/client";

const onElicitation: OnElicitationCallback = async (params) => {
  if (params.mode === "url") {
    console.log(`Visit: ${params.url}`);
    return { action: "accept" };
  }
  // Form mode — collect fields from params.requestedSchema
  return acceptWithDefaults(params);
};

const client = new MCPClient(config, { onElicitation });
```

## Helpers

Import from `@mcp-use/client`:

| Helper                         | Purpose                      |
| ------------------------------ | ---------------------------- |
| `acceptWithDefaults(params)`   | Accept using schema defaults |
| `accept(content)`              | Accept with user content     |
| `decline()`, `cancel()`        | Reject or dismiss            |
| `validate(params, content)`    | Client-side validation       |
| `getDefaults`, `applyDefaults` | Work with schema defaults    |

## React

```tsx theme={null}
const mcp = useMcp({
  url: "http://localhost:3000/mcp",
  onElicitation: (params) => acceptWithDefaults(params),
});
```

With the provider, use `pendingElicitationRequests` and `approveElicitation` / `rejectElicitation`.

Without an `onElicitation` handler, tool calls that require input will fail.
