WHAT IT DOES

What set_bridge_fee_rate does on Tenzro Ledger MCP

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

RISK

Why set_bridge_fee_rate is rated Critical

Setting a bridge fee rate directly affects financial transactions by changing the cost of cross-chain transfers. This is a financial configuration action with significant blast radius if misused (e.g., setting fees to 0 or 100%). The description is empty, lowering confidence slightly, but the name and server context strongly suggest a financial/write operation. Financial takes precedence over Write.

From the tool's definition Tool name 'set_bridge_fee_rate' on a server described as handling 'payments, staking, bridges' — implies modifying financial parameters for cross-chain bridge operations.
