Implementation Reference
- src/index.ts:721-734 (handler)MCP tool handler for 'get_metrics': calls metrics.getMetrics() and returns the JSON-stringified metrics data as tool response.
case 'get_metrics': { const metricsData = metrics.getMetrics() await logger.debug('Retrieved metrics') endMetric() return { content: [ { type: 'text', text: JSON.stringify(metricsData, null, 2), }, ], } } - src/metrics/index.ts:93-112 (helper)Core implementation of getMetrics(): aggregates operation stats (count, errors, avgTime) and adds uptime metric.
public getMetrics(): Record<string, MetricsResult> { const result: Record<string, MetricsResult> = {} for (const [name, data] of Object.entries(this.operations)) { result[name] = { count: data.count, errors: data.errors, avgTime: data.count > 0 ? data.totalTime / data.count : 0, } } // Add uptime metric result['uptime_ms'] = { count: 1, errors: 0, avgTime: performance.now() - this.startTime, } return result } - src/index.ts:336-346 (registration)Registration of 'get_metrics' tool in the tools list for list_tools handler, including empty input schema (no arguments required).
