# Claude Agent SDK

> Use Corsair with the Claude Agent SDK via an in-process MCP server — no HTTP transport needed.

Use `ClaudeProvider` to connect Corsair to the [Claude Agent SDK](https://github.com/anthropics/claude-agent-sdk) with an in-process MCP server. No HTTP transport needed.

## Install

```bash theme={null}
npm install @anthropic-ai/claude-agent-sdk @corsair-dev/mcp
```

## Usage

```ts agent.ts theme={null}
import { createSdkMcpServer, query } from '@anthropic-ai/claude-agent-sdk';
import { ClaudeProvider } from '@corsair-dev/mcp';
import { corsair } from './corsair';

const provider = new ClaudeProvider();
const tools = await provider.build({ corsair });
const server = createSdkMcpServer({ name: 'corsair', tools });

const stream = query({
    prompt: 'List my GitHub repos with the most open issues.',
    options: {
        model: 'claude-opus-4-6',
        mcpServers: { corsair: server },
    },
});

for await (const event of stream) {
    if ('result' in event) process.stdout.write(event.result);
}
```

`ClaudeProvider.build()` is async — it dynamically imports the Claude Agent SDK as an optional peer dependency.

The Claude Agent SDK handles the tool-call loop automatically via `query()`.
