🇰🇷 한국어 | 🇯🇵 日本語 | 🇨🇳 简体中文 | 🇹🇼 繁體中文 | 🇧🇷 Português

The OP.GG MCP Server is a Model Context Protocol implementation that provides AI agents with access to OP.GG game data for League of Legends, Teamfight Tactics, and Valorant.

Endpoint

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

{
  "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}"
  ]
}
