### Claude Desktop Configuration

Add to your Claude Desktop config file:

**macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
**Windows**: `%APPDATA%\Claude\claude_desktop_config.json`

```json
{
  "mcpServers": {
    "kalshi": {
      "command": "python",
      "args": ["-m", "kalshi_mcp"],
      "env": {
        "KALSHI_API_KEY": "your-api-key-here",
        "KALSHI_PRIVATE_KEY_PATH": "C:\\Users\\YourName\\.trading_keys\\kalshi_private_key.pem"
      }
    }
  }
}
```

**Note**:

- Update the private key path to where you saved your `.pem` file
- On Windows, use double backslashes (`\\`) in paths

## Authentication

This server uses **RSA-PSS signature authentication**:
1. Each request is signed with your private key
2. Kalshi verifies the signature with your public key
3. Thread-safe rate limiting (150ms between requests)
4. Automatic retry on 429 rate limit errors

**Security**: Your private key never leaves your machine. The server only signs requests locally.

## Rate Limiting

- Built-in 150ms spacing between requests (~6.6 req/s)
- Automatic exponential backoff on 429 errors (0.5s → 1s → 2s)
- Safe for concurrent use across multiple Claude conversations

## Architecture

Built on production code from a live Kalshi trading bot:
- **Authentication**: Reused from `kalshi_client.py` (4+ months uptime)
- **Rate limiting**: Shared across all client instances
- **Error handling**: Battle-tested retry logic
- **Market discovery**: Liquidity scoring from `scanner.py`
