SERP ENGINE

Google Flights

Two tools over Google Flights, live via SerpAPI. The search tool covers round trips, one-way and multi-city itineraries and returns best_flights and other_flights — each with legs, airlines, times, durations, layovers, price and carbon emissions — plus price_insights. Two-step flows are supported: pass back a departure_token to get returning flights, or a booking_token to get booking options. The deals tool flips the question around: give it only an origin and it discovers cheap destinations for you.

Connect

Thirty seconds, any client.

claude mcp add --transport http google-flights https://mcp.wondel.ai/google-flights/mcp

One command in your terminal — the server is available in every Claude Code session.

01Open Settings → Connectors in Claude.ai or the desktop app 02Click Add custom connector 03Paste the endpoint URL:

https://mcp.wondel.ai/google-flights/mcp

Works on every Claude plan that supports custom connectors.

{
  "mcpServers": {
    "google-flights": {
      "url": "https://mcp.wondel.ai/google-flights/mcp"
    }
  }
}

Add to .cursor/mcp.json, VS Code's mcp.json, or any client that takes an mcpServers map.

npx mcp-remote https://mcp.wondel.ai/google-flights/mcp

For stdio-only clients: mcp-remote bridges the remote endpoint to a local process. Streamable HTTP-capable clients can hit the URL directly — a legacy /sse endpoint exists too.

This server works with Claude, Claude Code, Claude Desktop, Claude Cowork, Cursor, VS Code, Windsurf — and any other MCP client. Stdio-only clients connect through npx mcp-remote.

The Tools

2 tools, fully typed.
