# SDK

> The Mutagent SDK — authenticate to the Platform from TypeScript or Python.

The Mutagent SDK lets your code authenticate to the Platform and manage account resources
programmatically. Install the CLI for interactive use; use the SDK when you're scripting against the
Platform from TypeScript or Python.

<Note>
  The SDK's job today is **authentication and account resources** — signing in and managing
  providers. The ADLC loop itself is driven by [Helix](/helix/what-is-helix) in your coding agent,
  not by an SDK call.

## Construct a client

The SDK exports a `Mutagent` client. It reads `MUTAGENT_API_KEY` from the environment by default:

```typescript theme={null}
import { Mutagent } from '@mutagent/sdk';

const client = new Mutagent();   // uses MUTAGENT_API_KEY
```

From there you manage [providers](/sdk/typescript/providers) and account configuration. See
[configuration](/sdk/typescript/configuration) for the client options.
