Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mcp-flight-search find flights from JFK to LAX on 2024-12-15"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
MCP Flight Search
An MCP server that searches Google Flights through SerpApi, for Claude, Cursor and other MCP clients. One-way and round-trip searches by IATA airport code, with prices, durations, stops and times.
Requirements
Python 3.10 or later (or uv)
A SerpApi key in
SERP_API_KEY(serpapi.com has a free tier)
Related MCP server: Google-Flights-MCP-Server
Use it from an MCP client
Add it to your client's MCP configuration (Claude Desktop, Claude Code, Cursor, ...):
{
"mcpServers": {
"flight-search": {
"command": "uvx",
"args": ["mcp-flight-search"],
"env": { "SERP_API_KEY": "your-serpapi-key" }
}
}
}Or install it with pip install mcp-flight-search and use "command": "mcp-flight-search".
Run it yourself
export SERP_API_KEY="your-serpapi-key"
mcp-flight-search # stdio (default)
mcp-flight-search --connection_type http --port 3001 # Streamable HTTP at http://127.0.0.1:3001/mcpLOG_LEVEL=DEBUG shows more detail on stderr. The API key is never logged.
With Docker:
docker build -t mcp-flight-search .
docker run -i --rm -e SERP_API_KEY=your-serpapi-key mcp-flight-searchTools

A3.6/5.0
Scored across 2 tools
Disambiguation5/5
The two tools serve entirely distinct purposes: one performs a flight search, the other reports server health. There is no plausible way to confuse them, and the descriptions make the boundary explicit.
Naming Consistency3/5
Both names are snake_case, but the convention is inconsistent: 'search_flights_tool' uses a redundant '_tool' suffix and a verb_verb_noun shape, while 'server_status' is a plain noun phrase. Readable, but the pattern isn't predictable.
Tool Count3/5
Two tools is thin for a flight search server; the health-check tool arguably doesn't earn a slot as a first-class tool. It's a borderline-surface rather than an extreme mismatch.
Completeness3/5
Flight search is covered, but obvious adjacent operations are absent: airport/location lookup, date-range or fare-calendar search, multi-city itineraries, and filtering/sorting of results. An agent can do the core task but will hit dead ends on common follow-ups.
