Review before connecting
The findings on this server are worth reviewing before you connect an agent to it.
Scanned 27 days ago Due for re-check
A server can change after it's graded. Re-run the automated scan to refresh this report.
This grade is deterministic and reproducible: the same server surface always yields the same grade under a given algorithm version. It is a real automated assessment computed by the MCPGrade engine from what the probe actually observed — not a fabricated or opinion score. It is not a manual human pentest, so it can miss context-specific risks.
Every signal below was measured directly by the automated probe. The grade is derived only from evidence like this — nothing is assumed.
The Flight Search MCP Server MCP server exposes 4 tools across a range of capabilities. Its published description reads: "Integrates with multiple flight data APIs to provide real-time flight search, price discovery across flexible date ranges, comprehensive travel reference data, and direct booking…". It communicates over Streamable HTTP using the 2025-06-18 protocol revision, and does not require authorization to connect. MCPGrade currently rates Flight Search MCP Server C+ — the findings are worth reviewing before you connect an agent to it. Its most notable finding was "No authorization on a public remote server". This report is a deterministic, reproducible automated assessment: the same observed surface always yields the same grade under a given algorithm version, and it is refreshed as new scans arrive and free to read — but it is not a substitute for a manual human security review. Always re-check Flight Search MCP Server's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
