Q&A

Do I need special knowledge to integrate the MCP server into my AI agent?

Yes, you’ll need to understand the Model Context Protocol and OP.GG’s data structures, especially the field‑selection syntax, to correctly format requests and parse responses.

What transport protocol does the OP.GG MCP Server use, and how do I access it?

It uses Streamable HTTP transport. All endpoints are reachable via the base URL `https://mcp.api.op.gg/mcp`, where you send standard HTTP requests with the required parameters.

Which games and data categories are available through the MCP server?

The server supports three games—League of Legends, Teamfight Tactics, and Valorant—and offers tools such as champion analysis, synergy info, lane guides, summoner profiles, match histories, discounted skins, item lists, esports schedules, and leaderboards.

Asked by Xiomara Delgado · Nov 6, 2025

How do I limit the data returned by the OP.GG MCP Server to reduce payload size?

You can use the `desired_output_fields` parameter to specify exactly which fields you need, following the field selection syntax (e.g., `data.summoner.{level name}` or `champions[].{name title}`). This trims the response to only the requested data.
