## MCP Configuration

### Cursor

Add to your Cursor settings (`.cursor/mcp_settings.json` or via Settings UI):

```json
{
"mcpServers": {
"csharp-eval": {
"command": "docker",
"args": ["run", "-i", "--rm", "ghcr.io/infinityflowapp/csharp-mcp:latest"],
"env": {
"CSX_ALLOWED_PATH": "/scripts"
}
}
}
}
```

Or if installed as a dotnet tool:

```json
{
"mcpServers": {
"csharp-eval": {
"command": "infinityflow-csharp-eval",
"env": {
"CSX_ALLOWED_PATH": "${workspaceFolder}/scripts"
}
}
}
}
```

### Claude Code

Add to your Claude Code configuration (`claude_desktop_config.json`):

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