# Anthropic

> Connect Anthropic to your Atako agents — 9 read and 5 write actions.

Let your agents call Claude models — send messages, count tokens, run batches and manage files on your behalf.

## Connection

* **Authentication**: API key (API key (sk-ant-...)).

<Note>
  console.anthropic.com → Settings → API keys → Create Key. Pick the workspace to scope it to, name the key, then copy the value (starts with sk-ant-). No extra scopes needed — a standard API key covers Messages, Batches, Files and Models.

  See [Anthropic's documentation](https://console.anthropic.com/settings/keys).
