But `_enrich_search_results` fetches every hit with `self.zotero_client.item(item_key)`, a single client bound to the *active* library.

      "Excerpt": "The web API works fine. But for local API, I've tried on both [Smithery](https://smithery.ai/server/%4054yyyu%2Fzotero-mcp/tools) and VS Code, both get the error message:\n```\n[Errno 111] Connection refused\n```\n\nI can ensure local API is enabled in Zotero advanced settings. And in command line:\n```\ncurl http://localhost:23119/api/users/0/items?limit=1\n```\nworks fine and returns a recent item.",
