ot_sell · Ttt MCP: Risk & Policy

WHAT IT DOES

What ot_sell does on Ttt

AI agents use ot_sell to commit financial operations through Ttt — usually the final step of a payment, billing, or trading workflow. A call moves real money.

WHY IT NEEDS A POLICY

Why ot_sell needs a policy

The tool performs a sell operation, which exchanges in-game goods for currency or credits. Even in a game context, 'sell' operations fall under Financial as they move value/resources. The description is truncated ('You' is cut off), which reduces confidence slightly, but the core action is clearly a sale transaction. Severity is high because misuse could deplete in-game resources or currency irreversibly.

From the tool's definition 'Sell surplus supplies at a trading post or fort' — selling items for currency is a financial transaction
