Implementation Reference
- index.js:637-656 (handler)Primary handler for the get_index_recommendations tool. Delegates to QueryOptimizer.analyzeIndexUsage and formats JSON response.
async getIndexRecommendations(database) { try { const recommendations = await this.queryOptimizer.analyzeIndexUsage(database); return [ { type: 'text', text: JSON.stringify( { success: true, data: recommendations }, null, 2 ) } ]; } catch (error) { throw new McpError(ErrorCode.InternalError, error.message); } } - lib/analysis/query-optimizer.js:738-757 (handler)Core implementation logic for generating index recommendations (placeholder implementation). Called by main handler.
async analyzeIndexUsage(database) { // Basic index recommendations - this would normally query SQL Server DMVs return { database, timestamp: new Date().toISOString(), recommendations: [ { type: 'missing_index', priority: 'high', suggestion: 'Consider adding indexes on frequently queried columns', impact: 'Could improve query performance by 50-80%', table: 'example_table', columns: ['column1', 'column2'] } ], unusedIndexes: [], duplicateIndexes: [], fragmentedIndexes: [] }; } - lib/tools/tool-registry.js:177-194 (schema)Tool definition with name, description, and input schema used for MCP tool listing and validation.
