Implementation Reference
- src/index.ts:203-228 (handler)MCP tool handler for 'clear_cache': handles optional 'key' argument, calls cacheManager.delete(key) if provided or cacheManager.clear() otherwise, and returns appropriate success/error text response.
case 'clear_cache': { const { key } = request.params.arguments as { key?: string }; if (key) { const success = this.cacheManager.delete(key); return { content: [ { type: 'text', text: success ? `Successfully cleared cache entry: ${key}` : `No cache entry found for key: ${key}`, }, ], }; } else { this.cacheManager.clear(); return { content: [ { type: 'text', text: 'Successfully cleared all cache entries', }, ], }; } } - src/index.ts:135-147 (schema)Tool definition including name, description, and input schema for 'clear_cache' used in ListTools response (serves as registration and schema).
{ name: 'clear_cache', description: 'Clear specific or all cache entries', inputSchema: { type: 'object', properties: { key: { type: 'string', description: 'Specific key to clear (optional - clears all if not provided)', }, }, }, }, - src/CacheManager.ts:91-100 (helper)CacheManager.delete(key) method: removes specific cache entry if exists, updates stats, returns success boolean.
delete(key: string): boolean { const entry = this.cache.get(key); if (entry) { this.stats.memoryUsage -= entry.size; this.cache.delete(key); this.stats.totalEntries = this.cache.size; return true; } return false; } - src/CacheManager.ts:102-105 (helper)CacheManager.clear() method: clears all cache entries and resets statistics.
clear(): void { this.cache.clear(); this.resetStats(); }
