Implementation Reference

• src/server.ts:196-206 (handler)

  Handler for the metrics.refreshNow tool: calls refreshMetrics() and returns success response.

  case 'metrics.refreshNow': {
    await this.refreshMetrics();
    return {
      content: [
        {
          type: 'text',
          text: 'Metrics refreshed successfully'
        }
      ]
    };
  }

• src/server.ts:118-125 (registration)

  Registration of metrics.refreshNow tool including name, description, and input schema.

  {
    name: 'metrics.refreshNow',
    description: 'Re-parses the Markdown file and reloads the in-memory cache',
    inputSchema: {
      type: 'object',
      properties: {},
    },
  },

• src/server.ts:293-315 (helper)

  Core helper function implementing metric refresh: parses markdown, saves to loader, clears cache, updates search engine.

  private async refreshMetrics(): Promise<void> {
    try {
      const parser = new MarkdownParser(this.markdownPath);
      const parsedMetrics = parser.parseMetrics();
      
      const metricsFile: MetricsFile = {
        version: parser.getVersion(),
        updatedAt: parser.getLastUpdated(),
        metrics: parsedMetrics
      };
  
      this.metricsLoader.saveMetrics(metricsFile);
      this.metricsLoader.clearCache();
      
      // Update search engine
      this.searchEngine = new MetricsSearch(parsedMetrics);
      
      // console.log(`Refreshed ${parsedMetrics.length} metrics from markdown`);
    } catch (error) {
      console.error('Failed to refresh metrics:', error);
      throw error;
    }
  }
