AgentProvider

AgentProvider is the root component for the Agent SDK. It sets up the chat engine, theming, and provides context to all child components.

Usage

import { AgentProvider, AgentChat } from '@kapaai/agent-react';

<AgentProvider
  getSessionToken={async () => {
    const res = await fetch('/api/session', { method: 'POST' });
    return res.json();
  }}
  projectId="your-project-id"
  integrationId="your-integration-id"
  tools={myTools}
  context={myContext}
  builtinToolMeta={{
    search_knowledge_base: { displayName: 'Search Knowledge Base' },
  }}
  theme={{ accentColor: '#2563eb', colorScheme: 'dark' }}
>
  <AgentChat branding={{ title: 'AI Assistant' }} />
</AgentProvider>

ToolDisplayMeta

The agent includes a built-in search_knowledge_base tool that searches your project's knowledge base server-side. Since it's not a client tool, you can't define or execute it — but you can customize how it appears in the chat. See Built-in tools for details.

builtinToolMeta={{
  search_knowledge_base: {
    displayName: 'Search Knowledge Base',
    icon: IconSearch,       // optional
    iconColor: '#38bdf8',   // optional
  },
}}
