# change_margin_mode A financial tool on the Bitunix MCP MCP server. Agent View of the PolicyLayer registry record for `change_margin_mode`. HTML page: https://policylayer.com/tools/luiinventions-bitunix-mcp/change-margin-mode ## Facts - Tool: `change_margin_mode` - Server: Bitunix MCP (`luiinventions/bitunix-mcp`) — https://policylayer.com/tools/luiinventions-bitunix-mcp.md - Homepage: https://github.com/LuiInventions/Bitunix-MCP - Risk category: Financial (Critical risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Approval-gated ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "change_margin_mode", "arguments": {} } } ``` ## Why change_margin_mode is rated Critical This tool operates on a financial trading platform that explicitly supports futures trading with leverage. Changing margin mode (e.g., between cross and isolated margin) directly affects how losses are calculated and how much capital is at risk across positions. From the tool's own definition: "Tool name 'change_margin_mode' on a trading/futures exchange MCP server (Bitunix) that supports 'futures and spot trading with advanced order management, leverage, and TP/SL'" ## Use case AI agents use change_margin_mode to commit financial operations through Bitunix MCP, usually the final step of a payment, billing, or trading workflow. A call moves real money. ## Recommended policy (PolicyLayer) Verdict: **Approval-gated**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Bitunix MCP: ```json { "version": "1", "default": "deny", "tools": { "change_margin_mode": { "deny_if": [ { "conditions": [], "on_deny": "Requires human approval." } ] } } } ``` ## Other tools on Bitunix MCP (36) - `cancel_orders` — Destructive — https://policylayer.com/tools/luiinventions-bitunix-mcp/cancel-orders.md - `change_position_mode` — Execute — https://policylayer.com/tools/luiinventions-bitunix-mcp/change-position-mode.md - `adjust_position_margin` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/adjust-position-margin.md - `batch_order` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/batch-order.md - `cancel_all_orders` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/cancel-all-orders.md - `cancel_tpsl_order` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/cancel-tpsl-order.md - `change_leverage` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/change-leverage.md - `close_all_positions` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/close-all-positions.md - `convert_currency` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/convert-currency.md - `flash_close_position` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/flash-close-position.md - `funds_transfer` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/funds-transfer.md - `modify_order` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/modify-order.md - `modify_position_tpsl_order` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/modify-position-tpsl-order.md - `modify_tpsl_order` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/modify-tpsl-order.md - `place_order` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/place-order.md - `place_position_tpsl_order` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/place-position-tpsl-order.md - `place_tpsl_order` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/place-tpsl-order.md - `set_leverage_and_margin_mode` — Financial — https://policylayer.com/tools/luiinventions-bitunix-mcp/set-leverage-and-margin-mode.md - `get_account` — Read — https://policylayer.com/tools/luiinventions-bitunix-mcp/get-account.md - `get_batch_funding_rate` — Read — https://policylayer.com/tools/luiinventions-bitunix-mcp/get-batch-funding-rate.md - `get_funding_rate` — Read — https://policylayer.com/tools/luiinventions-bitunix-mcp/get-funding-rate.md - `get_history_orders` — Read — https://policylayer.com/tools/luiinventions-bitunix-mcp/get-history-orders.md - `get_history_positions` — Read — https://policylayer.com/tools/luiinventions-bitunix-mcp/get-history-positions.md - `get_history_tpsl_orders` — Read — https://policylayer.com/tools/luiinventions-bitunix-mcp/get-history-tpsl-orders.md - `get_history_trades` — Read — https://policylayer.com/tools/luiinventions-bitunix-mcp/get-history-trades.md - `get_kline` — Read — https://policylayer.com/tools/luiinventions-bitunix-mcp/get-kline.md - `get_leverage_margin_mode` — Read — https://policylayer.com/tools/luiinventions-bitunix-mcp/get-leverage-margin-mode.md - `get_order_book` — Read — https://policylayer.com/tools/luiinventions-bitunix-mcp/get-order-book.md - `get_order_detail` — Read — https://policylayer.com/tools/luiinventions-bitunix-mcp/get-order-detail.md - `get_pending_orders` — Read — https://policylayer.com/tools/luiinventions-bitunix-mcp/get-pending-orders.md - …and 6 more: https://policylayer.com/tools/luiinventions-bitunix-mcp.md ## For agents This record is a snapshot.
