ttt_make_move · Ttt MCP: Risk & Policy

WHAT IT DOES

What ttt_make_move does on Ttt

AI agents invoke ttt_make_move to trigger actions in Ttt. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why ttt_make_move needs a policy

Making a move in tic-tac-toe modifies the game state (places a piece on the board), which is a state-changing operation. It is not purely read, but also not destructive or financial. It falls under Execute as it triggers an external operation (game engine move processing). Severity is low since the blast radius is limited to a game state with no real-world consequences.

From the tool's definition Tool name 'ttt_make_move' and partial description 'Place the current player' indicate placing a game piece, triggering a state change in the tic-tac-toe game.
