make_move · Gomoku MCP: Risk & Policy

WHAT IT DOES

What make_move does on Gomoku

AI agents use make_move to create or update resources in Gomoku — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Gomoku environment.

WHY IT NEEDS A POLICY

Why make_move needs a policy

This tool writes a game move to the board, modifying the game state. It is reversible in the sense that game state is just data, and there is no destructive, financial, or code-execution aspect. Blast radius is very low as it only affects a game session.

From the tool's definition 在指定位置下棋 (make a move at a specified position) — creates/modifies game state by placing a piece on the board

Verdict

make_move Rate-limited

make_move stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
