Slg MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 984 installs a week from npm. Last commit 8 Nov 2026.
Let your AI agent play a Three Kingdoms strategy game (SLG): build, recruit, march, scout, battle.
Nothing serious here today
Today is the operative word: we check Slg MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
