Run this in your terminal

claude mcp add flight-search --env SERP_API_KEY=your-value -- uvx mcp-flight-search

Fill in the empty values before running it.

Open in Cursor

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "flight-search": {
      "command": "uvx",
      "args": [
        "mcp-flight-search"

Common questions

Is Flight Search safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: SERP_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.3.0) reached the registry 25 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

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)

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/mcp

LOG_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-search

Tools
