# Anthropic SDK

> Connect Corsair to the Anthropic SDK using tool use.

Use `AnthropicProvider` to connect Corsair to the [Anthropic SDK](https://github.com/anthropics/anthropic-sdk-typescript) via native tool use.

## Install

```bash theme={null}
npm install @anthropic-ai/sdk
```

## Usage

```ts agent.ts theme={null}
import Anthropic from '@anthropic-ai/sdk';
import { AnthropicProvider } from '@corsair-dev/mcp';
import { corsair } from './corsair';

const provider = new AnthropicProvider();
const tools = provider.build({ corsair });
const client = new Anthropic();

const message = await client.beta.messages.toolRunner({
    model: 'claude-sonnet-4-6',
    max_tokens: 4096,
    tools,
    messages: [
        {
            role: 'user',
            content: 'Setup corsair, then list all Slack channels.',
        },
    ],
});

for (const block of message.content) {
    if (block.type === 'text') console.log(block.text);
}
```

`AnthropicProvider.build()` is synchronous — it returns the tools array directly, ready to pass to any Anthropic API call.

`toolRunner` handles the tool call loop automatically, invoking each tool and feeding results back until the model produces a final response.
