LogAnalyzer MCP Server

Instructions

Implementation Reference

• src/server.ts:324-344 (handler)

  MCP tool handler for 'quick_scan' that validates input, calls rapidDebugger.quickScan, and formats the MCPToolResult response.

  private async handleQuickScan(args: any): Promise<MCPToolResult> {
    const { logText } = args;
  
    if (!logText || typeof logText !== 'string') {
      throw new Error('logText is required and must be a string');
    }
  
    const scanResult = await this.rapidDebugger.quickScan(logText);
  
    return {
      success: true,
      data: {
        ...scanResult,
        message: `⚡ Quick scan completed in ${scanResult.time}ms`
      },
      metadata: {
        processedAt: new Date(),
        scanMode: 'quick'
      }
    };
  }

• src/server.ts:67-76 (schema)

  Input schema definition for the 'quick_scan' tool, specifying logText as required string.

  inputSchema: {
    type: 'object',
    properties: {
      logText: {
        type: 'string',
        description: 'Log content for quick error detection'
      }
    },
    required: ['logText']
  }

• src/server.ts:64-77 (registration)

  Registration of the 'quick_scan' tool in the ListToolsRequestHandler response.

  {
    name: 'quick_scan',
    description: '⚡ Ultra-fast log scan for real-time monitoring (< 1 second)',
    inputSchema: {
      type: 'object',
      properties: {
        logText: {
          type: 'string',
          description: 'Log content for quick error detection'
        }
      },
      required: ['logText']
    }
  },

• src/tools/rapidDebugger.ts:227-239 (helper)

  Core implementation of quickScan logic: counts errors, detects critical issues, measures execution time.

  async quickScan(logContent: string): Promise<{errors: number, critical: boolean, time: number}> {
    const start = Date.now();
    const errors = LogUtils.extractErrorPatterns(logContent);
    const critical = logContent.toLowerCase().includes('fatal') || 
                    logContent.toLowerCase().includes('critical') ||
                    errors.length > 5;
    
    return {
      errors: errors.length,
      critical,
      time: Date.now() - start
    };
  }

• src/server.ts:177-179 (registration)

  Dispatch registration in the CallToolRequestHandler switch statement.

  case 'quick_scan':
    result = await this.handleQuickScan(args);
    break;
