Implementation Reference
- index.js:675-694 (handler)Main MCP tool handler function that executes the detect_query_bottlenecks tool by delegating to the BottleneckDetector class and formatting the response.
async detectQueryBottlenecks(database) { try { const bottlenecks = await this.bottleneckDetector.detectBottlenecks(database); return [ { type: 'text', text: JSON.stringify( { success: true, data: bottlenecks }, null, 2 ) } ]; } catch (error) { throw new McpError(ErrorCode.InternalError, error.message); } } - lib/tools/tool-registry.js:196-212 (schema)Input schema definition for the detect_query_bottlenecks tool, including parameters for database, limit, and severity filter.

case 'detect_query_bottlenecks': return { content: await this.detectQueryBottlenecks(args.database) }; - Core helper method in BottleneckDetector class that performs the actual bottleneck detection (currently a placeholder implementation). Additional helper methods like analyzeQuery, identifyBottleneckType exist in the same class for supporting logic.
async detectBottlenecks(query) { const pool = this.connectionManager.getPool(); if (!pool) { throw new Error('Not connected to any server'); } if (!query) { throw new Error('Query is required for detectBottlenecks'); } // Placeholder for actual implementation return Promise.resolve([]); }
