Opgg MCP: MCP server, setup and security

What Opgg MCP does

According to its repository: “Real-time gaming data for League of Legends, TFT and Valorant: champion analytics, esports schedules, meta compositions and character statistics.”

The Model Context Protocol (MCP) is a standard plug between an AI agent and an outside service: once the server is connected, its tools show up in the agent, which decides when to call them. Opgg MCP is listed under Gaming, a category of 44 servers in the directory, where it ranks #10 by stars.

Installing and connecting Opgg MCP

No package or remote server is declared in the official MCP registry: you install it from source, following the repository README.

It works with any MCP-compatible client (Claude Desktop, Claude Code, Cursor, VS Code, Codex and most recent agents). You add one entry to the client's MCP configuration: server name, start command or URL, environment variables. Project language: TypeScript.

Security: what to check

Connecting an MCP server means installing software that talks straight to your agent: it runs with your rights and the model trusts its tool descriptions. The risk therefore depends on what it can touch and how far its code can be trusted.

None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to Opgg MCP. That does not replace reading the code.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on April 8, 2025, the opgginc/opgg-mcp repository has 104 stars and 0 forks, with 1 open issues. It has more stars than 67% of the servers in the directory. It received changes this month.

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
