async closePosition(dealId) { try { const positions = await this.getPositions(); const position = positions.positions.find(p => p.position.dealId === dealId); if (!position) { throw new Error(`Position ${dealId} not found`); } const closeTicket = { dealId, direction: position.position.direction === 'BUY' ? 'SELL' : 'BUY', orderType: 'MARKET', size: position.position.size }; const response = await this.apiClient.delete('/positions/otc', closeTicket, 1); if (response.data.dealReference) { const confirmation = await this.getConfirmation(response.data.dealReference); return { position: response.data, confirmation }; } return response.data; } catch (error) { logger.error(`Failed to close position ${dealId}:`, error.message); throw error; } } - src/services/mcp-service.js:214-227 (schema)Tool schema definition including name, description, and input validation requiring dealId.
