create_room · Gomoku MCP: Risk & Policy

WHAT IT DOES

What create_room does on Gomoku

AI agents use create_room 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 create_room needs a policy

The tool performs a write operation by creating a new game room resource. While this modifies server state, it is fully reversible (rooms can be deleted/left), involves no deletion, execution of arbitrary code, or financial impact. The blast radius of misuse is minimal—at worst, an agent could spam room creation, which is a low-severity issue for a gaming server.

From the tool's definition Tool creates a new game room ("创建游戏房间" = "create game room"), which initializes reversible game state. This is a write operation that generates new data without destructive or financial consequences.

Verdict

create_room Rate-limited

create_room 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.
