| Client coverage note | Local stdio runs on your computer. Streamable HTTP connects to a remotely hosted MCP server. | |
| Access and data | ||
| Authentication | Local mode needs no API key. The reviewed README does not specify Web API credentials. Optional OpenAI and Gemini embeddings require provider API keys. | No MCP or Google API key or OAuth requirement is documented. The guide notes that some vendor fares may require a browser-minted session token. |
| Cost | The MIT-licensed server lists no MCP fee. Optional embedding providers and external services can have separate costs. | No project or API price is documented. Provider, booking-vendor, client, and model charges remain separate or unknown. |
| Permissions | Reads Zotero metadata, collections, tags, full text, and annotations; performs semantic search and citations; and can create or update notes and annotations, add papers, manage collections, update metadata, tags, and duplicates. | Searches Google Flights by route, dates, passengers, filters, and locale, and returns itineraries, fares, and airline, OTA, or direct booking links. No purchase action is documented. |
| Data handling | Local mode reads the local library and attachments; Web API mode accesses cloud data; hybrid reads locally and writes through the API. Embeddings can use local models, OpenAI, Gemini, or Ollama; retention is not documented. | Search parameters are sent to the publisher-described reverse-engineered Google Flights API. Results include itinerary, price, and booking-link data; storage, telemetry, and retention are not documented. |
| Limitations | ||
| Tradeoffs |
|
|
| Risk context | Write tools can alter a research library, while PDFs, full text, and cloud integrations can expose sensitive research. Start local and read-focused, restrict libraries, and supervise writes. | The publisher describes a reverse-engineered API and vendor-fare limitations, so independently verify prices and availability before purchase. Keep configurable HTTP mode local because MCP authentication is not documented. |
