Implementation Reference
- src/tools/getDevLogs.ts:28-101 (handler)The main handler function `getDevLogs` that executes the tool logic: retrieves logs from the dev server process using ProcessManager and LogManager, formats them, adds statistics, and returns JSON.export async function getDevLogs(args: { lines?: number; directory?: string }): Promise<string> { try { const requestedLines = args.lines || 50; const processManager = ProcessManager.getInstance(); // Determine which process to look at const processInfo = processManager.getProcess(args.directory); if (!processInfo) { return JSON.stringify({ success: false, message: 'Dev serverが起動していません（または指定されたディレクトリが見つかりません）', logs: [] }); } const logManager = processManager.getLogManager(processInfo.directory); if (!logManager) { return JSON.stringify({ success: false, message: 'ログマネージャーが見つかりませんでした', logs: [] }); } const logs = await logManager.getLogs(requestedLines); // Format logs for better readability const formattedLogs = logs.map(log => ({ timestamp: log.timestamp.toISOString(), level: log.level, source: log.source, message: log.message })); const logStats = logManager.getLogStats(); const result = { success: true, message: `${logs.length}行のログを取得しました`, logs: formattedLogs, statistics: { totalLogs: logStats.total, errors: logStats.errors, warnings: logStats.warnings, info: logStats.info, requested: requestedLines, returned: logs.length }, process: { pid: processInfo.pid, directory: processInfo.directory, status: processInfo.status } }; if (logStats.errors > 0) { result.message += `\n⚠️ ${logStats.errors}個のエラーが含まれています`; } return JSON.stringify(result, null, 2); } catch (error) { logger.error('Failed to get dev server logs', { error }); return JSON.stringify({ success: false, message: `ログ取得に失敗しました: ${error}`, logs: [], error: String(error) }); } }
- src/tools/getDevLogs.ts:7-26 (schema)The Tool schema definition `getDevLogsSchema` including name, description, and inputSchema with properties for lines and directory.export const getDevLogsSchema: Tool = { name: 'get_dev_logs', description: 'npm run devのログ取得', inputSchema: { type: 'object', properties: { lines: { type: 'number', description: '取得行数（デフォルト：50）', minimum: 1, maximum: 1000 }, directory: { type: 'string', description: '対象ディレクトリ（複数起動時に指定）' } }, additionalProperties: false } };
- src/index.ts:157-165 (registration)Registration and dispatch of the get_dev_logs handler in the main CallToolRequestSchema switch statement.case 'get_dev_logs': return { content: [ { type: 'text', text: await getDevLogs(args as { lines?: number; directory?: string }), }, ], };
- src/index.ts:55-65 (registration)Registration of the getDevLogsSchema in the tools array used for ListToolsRequestSchema response.const tools = [ scanProjectDirsSchema, startDevServerSchema, getDevStatusSchema, getDevLogsSchema, stopDevServerSchema, restartDevServerSchema, getHealthStatusSchema, recoverFromStateSchema, autoRecoverSchema, ];
- src/initialization/MCPServerInitializer.ts:13-23 (registration)Dependency registration for get_dev_logs tool, requiring 'stateManager' service in MCPServerInitializer.export const SERVICE_DEPENDENCIES = { 'scan_project_dirs': ['projectContext'], 'start_dev_server': ['stateManager'], 'get_dev_status': ['stateManager'], 'get_dev_logs': ['stateManager'], 'stop_dev_server': ['stateManager'], 'restart_dev_server': ['stateManager'], 'get_health_status': ['healthChecker'], 'recover_from_state': ['stateManager'], 'auto_recover': ['stateManager', 'healthChecker'] } as const;
