+An MCP server can request additional information from the user by sending an elicitation request. Set up an elicitation callback to handle these requests:
+
+```typescript
+// server.ts
+import { McpServer } from '@modelcontextprotocol/sdk/server/mcp.js'
+import { StdioServerTransport } from '@modelcontextprotocol/sdk/server/stdio.js'
+import { z } from 'zod'
+
+const server = new McpServer({
+  name: 'File Tools',
+  version: '1.0.0',
+})
+
+server.tool(
+  'delete_files',
+  'Delete the given files after getting user approval.',
+  {
+    paths: z.array(z.string()),
+  },
+  async ({ paths }) => {
+    const result = await server.server.elicitInput({
+      message: `Do you want to delete ${paths.join(', ')}?`,
+      requestedSchema: {
+        type: 'object',
+        properties: {
+          username: { type: 'string', description: 'Who is approving?' },
+        },
+        required: ['username'],
+      },
+    })
+
+    if (result.action !== 'accept') {
+      return { content: [{ type: 'text', text: `User ${result.action}ed deletion` }] }
+    }
+
+    // Perform deletion...
+    const username = (result.content as { username: string }).username
+    return { content: [{ type: 'text', text: `User ${username} approved deletion` }] }
+  }
+)
