Is Gaduin MCP server safe?

• None of the hidden-instruction wordings we know were found in its 12 tool descriptions.
• Its error messages showed no secrets or internal details.
• All 12 of its tools are labeled read-only.
• Overall it scored 95/100 on 12 Nov 2026.

A test can only see what the server shows from outside, not what it does with your data behind the scenes. Connect servers from makers you trust.

What this test does not check

• Its source code and packages.
• What a tool quietly does behind the scenes, such as writing a file or calling another service.
• Instructions hidden inside live tool answers. We only look for those in tool descriptions.
• Hidden instructions worded in a way our list doesn't know yet.
• Tools that could change something. Those are read, never run.

Known security advisories

It lists no public code, so there is nothing to look up in GitHub Security Advisories or OSV.dev. QAmcp tests how a server behaves. It does not scan source code.

What it can do

12 tools, in the server's own words.

  Tools work with good inputs

  All good

  • ✓list_markets: Worked (395 ms)
  • ✓get_market: Answered with an error, probably because of our sample input: No market has id "test". Call list_markets to find market ids.
  • ✓get_market_price_history: Answered with an error, probably because of our sample input: id must be a market UUID, as list_markets and get_market return it.
  • ✓get_flight_status: Answered with an error, probably because of our sample input: number must be a flight number such as BA117 or BAW117
  • ✓get_flight_history: Answered with an error, probably because of our sample input: number must be a flight number such as BA117 or BAW117
  • ✓search_flights: Worked (144 ms)
  • ✓get_airline_stats: Answered with an error, probably because of our sample input: code must be an airline IATA code such as BA or ICAO code such as BAW
  • ✓get_airport_status: Answered with an error, probably because of our sample input: TEST is not among the airports GADUIN reads. Call list_disrupted_airports for today's most disrupted ones.
