Side-by-side MCP evidence comparison
Evidence field	Zotero MCPShortlist candidate	Fli - Flight Search MCP Server and LibraryMCP100 Recommended
Task fit
Best for	Searching, reading, and organizing publisher-documented Zotero library metadata and research content through an MCP client	Searching flight options conversationally during early travel planning
Not ideal for	A complete literature review, authoritative citation validation, or document access outside the configured Zotero library	Booking, guaranteed live inventory, or final price confirmation
Avoid when	The library contains private notes, attachments, unpublished research, or credentials that must not reach the connected model	The workflow would make purchase decisions without verifying itinerary, baggage rules, fare terms, and current price at the provider

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	Direct library context can improve research assistance, while local or API setup and access to notes and attachments increase privacy and synchronization concerns.	Conversational search is convenient, but flight inventory changes quickly and upstream data coverage may not include every carrier or fare condition.
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.
