Free Google Flights MCP
https://server.smithery.ai/@mrabi/free-google-flights-mcp ↗
Description
Free real-time Google Flights search — one-way and round-trip — with no API key and no signup. ### What it returns - Live fares with airline, stops, duration and a bookable link - **Google's own price insights** (`price_insights_low` / `price_insights_high`) plus a low / typical / high verdict, so an agent can tell the user whether a fare is actually a good deal — most flight APIs don't expose this at all - Round-trip priced as **paired legs**, not two one-ways stitched together ### Flexible dates in a single call Pass a departure date range and/or several destinations, and the server fans out internally and merges the results. *"Cheapest flight to Sri Lanka anywhere in October"* is **one** tool call, not thirty. Every response carries `search_coverage` stating exactly which dates were searched, so a sampled scan is never mistaken for an exhaustive one. ### Tools | Tool | What it does | | --- | --- | | `search_oneway_flights` | One-way search — a single date, or a date range | |

Schema compliance
tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.

Availability history
Each block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Era history
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
No era measurements yet.
Response time history
The two probe legs separately: modern server/discover and legacy initialize.
No response-time measurements yet.
Event log
Derived by comparing consecutive probes — changes in era, protocol version, build and reachability.
