WHAT IT DOES

What close_leverage does on Basis MCP Server

AI agents use close_leverage to commit financial operations through Basis MCP Server, usually the final step of a payment, billing, or trading workflow. A call moves real money.

RISK

Why close_leverage is rated Critical

Closing a leverage position is a financial operation that settles outstanding margin/leveraged trades, potentially realizing gains or losses and moving funds. On a DeFi protocol like Basis on BNB Smart Chain, misuse could result in premature position closure, significant financial loss, or liquidation-level consequences. This clearly falls under Financial, which is the most severe applicable category.

From the tool's definition 'Close (or partially close) a leverage position' — directly closes financial leverage positions, which are financial instruments involving borrowed capital on a trading protocol
