Runs npx -y @mrfentmen/lichess-mcp on your machine. Read the scan report first; the gateway never runs local packages.

MCP server for Lichess, free chess, puzzles, and the best public chess API.

npm run build && node dist/index.js

Example:

get_daily_puzzle {}
get_player { username: "DrNykterstein" }   # Magnus, blitz 3153, 10,450 games
get_top_players { perf: "blitz", limit: 10 }

Keyless. Throttled to ~1 req/s to stay polite to the server. Closed/disabled accounts (e.g. hikaru) degrade gracefully.
