Parameters from the server's own tool schema.
This tool retrieves historical fill/trade data from a financial exchange. While it is a read operation (no side effects to accounts or positions), it accesses sensitive financial information about past trades. Severity is medium rather than low because exposure of detailed trade history could enable market manipulation reconnaissance, but it cannot directly move funds or execute new trades.
From the tool's definition Tool name 'swap_get_fills' and description 'Get SWAP/FUTURES fill details' indicate retrieval of historical trade data without modification or deletion. The mention of archive parameters (false/true) controlling time range confirms a query operation.
