Implementation Reference

• src/server/mcp-server.ts:321-330 (handler)

  The primary handler function for the 'get_cache_stats' tool. It calls the transcript service to get cache stats and formats the response as MCP content.
  private async handleGetCacheStats() { const stats = this.transcriptService.getCacheStats(); return { content: [{ type: 'text', text: JSON.stringify(stats, null, 2) }] }; }
• src/server/mcp-server.ts:206-213 (registration)

  Tool registration in the listAvailableTools method, defining the tool name, description, and input schema (empty object since no params required).
  { name: 'get_cache_stats', description: 'Get cache statistics and performance metrics', inputSchema: { type: 'object', properties: {} } },
• src/server/mcp-server.ts:209-212 (schema)

  Input schema definition for the get_cache_stats tool, specifying an empty object since the tool takes no parameters.
  inputSchema: { type: 'object', properties: {} }
• src/services/youtube-transcript.service.ts:349-350 (helper)

  Supporting method in the transcript service that delegates to the cache instance's getStats() method to retrieve statistics.
  public getCacheStats() { return this.cache.getStats();
