# Node.js SDK

Install and initialize the Scalekit Node.js SDK for AgentKit.
Install the Node.js SDK, create a `ScalekitClient`, then use the sidebar clients for AgentKit.

- **Connected accounts** (`scalekit.actions`) — connect end-user accounts and execute tools  
- **Tool calling** (`scalekit.tools`) — raw tool definitions for custom adapters  
- **Error handling** — typed exceptions for API failures  

## Install

```bash
npm install @scalekit-sdk/node
```

## Initialize

```ts wrap showLineNumbers=false

// Security: load credentials from environment variables — never hard-code secrets
const scalekit = new ScalekitClient(
  process.env.SCALEKIT_ENVIRONMENT_URL!,
  process.env.SCALEKIT_CLIENT_ID!,
  process.env.SCALEKIT_CLIENT_SECRET!
)
```

## Next steps

1. [Connected accounts](/agentkit/sdks/node/actions/) — authorization links, connected accounts, `executeTool`  
2. [Tool calling](/agentkit/sdks/node/tools/) — list tools for custom adapters  
3. [Error handling](/agentkit/sdks/node/errors/) — catch `ScalekitNotFoundException` and related types
