OGS MCP

Keyless MCP server for Online-Go.com: Go/Baduk/Weiqi players, ratings, recent games.

Pairs well with lichess-mcp, chess-mcp, and chesscom-mcp.

Quick start

npm install
npm run build
node dist/index.js

The server uses stdio, so it can be connected to Claude Desktop, Cursor, VS Code, MCP Inspector, or another compatible MCP client.

Tools at a glance

• search_players: Find players by username.
• get_player: Ratings per category and profile link.
• recent_games: Latest games with opponents and outcomes.

Limits and privacy

This project is intentionally narrow. It should be treated as a practical helper, not a complete certification or security audit. Check the implementation and the returned data before using it with sensitive material. No credentials are required.

Premium tools

These tools need a license key:

• game_record
• tournament_list

Buy a key at https://mcp-marketplace.io/server/io-github-mrfentmen-ogs-mcp and set it in your MCP client config:

"env": { "MCP_LICENSE_KEY": "mcp_live_..." }

The key is checked against MCP Marketplace, cached for 24 hours, and keeps working offline once one check has succeeded. Every other tool on this server stays free.
