Implementation Reference
- src/server/tools/CollectionTools.ts:147-157 (registration)Tool registration including name, description, empty input schema, and handler lambda delegating to server.getCollectionCacheHealth()
{ tool: { name: "get_collection_cache_health", description: "Get health status and statistics for the collection cache system. This helps monitor cache performance and identify any issues with offline browsing capability.", inputSchema: { type: "object", properties: {} } }, handler: () => server.getCollectionCacheHealth() } - The MCP tool handler function, which calls the server's getCollectionCacheHealth method
handler: () => server.getCollectionCacheHealth() - src/server/types.ts:40-40 (schema)TypeScript interface definition for the server method called by the tool handler
getCollectionCacheHealth(): Promise<any>; - src/cache/CollectionCache.ts:193-204 (helper)Core cache statistics computation for collection cache health: item count, age, and validity status
async getCacheStats(): Promise<{ itemCount: number; cacheAge: number; isValid: boolean }> { const cache = await this.loadCache(); if (!cache) { return { itemCount: 0, cacheAge: 0, isValid: false }; } return { itemCount: cache.items.length, cacheAge: Date.now() - cache.timestamp, isValid: Date.now() - cache.timestamp <= this.CACHE_TTL_MS }; } - Aggregated cache health stats from both index and collection caches, likely the data returned by getCollectionCacheHealth()
async getCacheStats(): Promise<any> { const indexStats = this.indexCache.getCacheStats(); const cacheStats = await this.collectionCache.getCacheStats(); return { index: indexStats, collection: cacheStats }; }
