MCP Tools

This skill uses the CrossEx MCP toolset with the cex_crx prefix as its only core tool family.

Scope rule: Only execute operations explicitly documented in this skill. Only call tools listed in the tables below or in references/*.md. Tools or operations not mentioned here must not be called.

Tool Naming Convention

• List operations in the cex_crx family query symbols, orders, positions, transfers, or history
• Get operations in the cex_crx family query a single account setting, fee, rate, or order detail
• Create operations in the cex_crx family create an order, transfer, convert quote, or convert order
• Update operations in the cex_crx family update account settings, leverage, or existing orders
• Cancel operations in the cex_crx family cancel an existing order
• Close operations in the cex_crx family close an existing position

Usage Guidance

• Use the cex_crx MCP family as the default and only core MCP family for this skill.
• Use list/get tools to query symbol rules, fees, balances, leverage, or supported assets.
• Prefer history and account-book tools when the user asks for records, audit trails, or status verification.

Execution

1. Intent and Parameter Identification

• Determine module (orders/positions/history)
• Extract key parameters:
  • Trading Pair: GATE_SPOT_BTC_USDT, GATE_MARGIN_XRP_USDT, GATE_FUTURE_ETH_USDT

  • Direction: BUY (buy/long), SELL (sell/short)
  • Quantity: USDT amount, coin quantity, contract size
  • Price: Limit, market
  • Leverage: Leverage multiplier (margin/futures only)
  • Position Side: LONG (long), SHORT (short, margin/futures only)
• Missing Parameters: If required parameters are missing, ask user

2. Pre-checks

Safety Rules

• Credentials: Never prompt or induce the user to paste API Secret Key into chat; prefer secure local MCP configuration.

• Trade Orders: Display complete order summary (pair, direction, quantity, price, leverage), require user confirmation before placing order
• Cross-Exchange Transfer: Display transfer details (source, destination, quantity, arrival time), require confirmation
• Scope rule: Only call tools documented in this skill. If the user requests an operation not documented here, respond that it is not supported by this skill.
• Batch Operations: Display operation scope and impact, require explicit confirmation

Example: "Reply 'confirm' to execute the above operation."
