## Endpoint

```
https://mcp-api.op.gg/mcp
```

The server supports **Streamable HTTP** transport.

## Field Selection

Most tools require a `desired_output_fields` parameter to specify which fields to return. This reduces payload size and improves response efficiency.

### Syntax

| Pattern | Description | Example |
|---------|-------------|---------|
| `field` | Single field | `name` |
| `parent.child` | Nested field | `data.summoner.level` |
| `array[]` | Array field | `champions[]` |
| `array[].field` | Field in array items | `data.champions[].name` |
| `{a,b,c}` | Multiple fields at same level | `{name,title,lore}` |
| `parent.{a,b}` | Multiple nested fields | `data.summoner.{level,name}` |
| `array[].{a,b}` | Multiple fields in array items | `data.champions[].{name,title}` |

### Example

```json
{
  "desired_output_fields": [
    "data.summoner.{game_name,tagline,level}",
    "data.summoner.league_stats[].{game_type,win,lose}",
    "data.summoner.league_stats[].tier_info.{tier,division,lp}"
  ]
}
```
