Installation

Quick Start (Recommended)

The easiest way to use this MCP server is with uvx:

uvx bing-flights-mcp

This will automatically install the package and its dependencies in an isolated environment.

Installation via pip

You can also install from PyPI:

pip install bing-flights-mcp

After installation, install the Playwright browser:

playwright install chromium

Development Installation

For development or if you want to modify the code:

1. Clone or download this repository

2. Create and activate a virtual environment

   On Windows:

   python -m venv venv
   venv\Scripts\activate
   

   On macOS/Linux:

   python -m venv venv
   source venv/bin/activate
   

3. Install dependencies

   pip install -r requirements.txt
   

4. Install Playwright browsers

   playwright install chromium
   

Usage

As an MCP Server

Using uvx (Recommended)

If you installed via PyPI, run:

uvx bing-flights-mcp

Or add to your MCP settings configuration:

{
  "mcpServers": {
    "bing-flights": {
      "command": "uvx",
      "args": ["bing-flights-mcp"]
    }
  }
}

Running from Source

If you're developing or running from source:

python mcp_server.py

Available Tools

The MCP server exposes two tools:

1. search_flights

Search for flight options from Bing Flights.

Parameters:

• origin (string, required): Origin airport code (e.g., "SEA")
• destination (string, required): Destination airport code (e.g., "ICN")
• departure_date (string, required): Departure date in YYYY-MM-DD format
• return_date (string, optional): Return date for round-trip searches
• adults (integer, optional, default=1): Number of adult passengers
• children (integer, optional, default=0): Number of child passengers
• infants (integer, optional, default=0): Number of infant passengers
• cabin_class (integer, optional, default=0): 0=Economy, 1=Premium Economy, 2=Business, 3=First
• max_results (integer, optional, default=10): Maximum number of results
• headless (boolean, optional, default=true): Run browser in headless mode

Example MCP Tool Call:

{
  "origin": "SEA",
  "destination": "ICN",
  "departure_date": "2025-11-30",
  "return_date": "2025-12-02",
  "adults": 1,
  "cabin_class": 0,
  "max_results": 10,
  "headless": true
}

2. get_scraper_status

Check scraper health and configuration.

Example Response:

{
  "status": "healthy",
  "version": "1.0.1",
  "capabilities": {
    "one_way_search": true,
    "round_trip_search": true,
    "cabin_classes": ["economy", "premium_economy", "business", "first"],
    "max_results": 50,
    "headless_mode": true
  }
}

As a Standalone Python Module

You can also use the scraper directly in your Python code:

from bing_flights_scraper import BingFlightsScraper

# Create scraper instance
scraper = BingFlightsScraper(headless=True)

try:
    # Search for flights
    results = scraper.search_flights(
        origin="SEA",
        destination="ICN",
        departure_date="2025-11-30",
        return_date="2025-12-02",
        adults=1,
        cabin_class=0,
        max_results=10
    )
    
    # Process results
    print(f"Found {results['results_count']} flights")
    for flight in results['flights']:
        print(f"Price: ${flight['price']['total']}")
        print(f"Airlines: {', '.join(flight['airlines'])}")
        print(f"Departure: {flight['outbound']['departure_time']}")
        print(f"Arrival: {flight['outbound']['arrival_time']}")
        print(f"Duration: {flight['outbound']['duration']}")
        print("---")
finally:
    scraper.close()

Response Format

The scraper returns results in the following JSON structure:

{
  "search_params": {
    "origin": "SEA",
    "destination": "ICN",
    "departure_date": "2025-11-30",
    "return_date": "2025-12-02",
    "trip_type": "round-trip",
    "passengers": {
      "adults": 1,
      "children": 0,
      "infants": 0
    },
    "cabin_class": "economy"
  },
  "results_count": 10,
  "flights": [
    {
      "price": {
        "total": 1200.00,
        "currency": "USD",
        "per_person": 1200.00
      },
      "airlines": ["Korean Air", "Delta"],
      "outbound": {
        "departure_time": "10:30",
        "arrival_time": "14:45",
        "duration": "13h 15m",

      "result_index": 1
    }
  ],
  "timestamp": "2025-10-23T02:19:00Z"
}

Configuration Options

Cabin Classes

• 0 - Economy
• 1 - Premium Economy
• 2 - Business
• 3 - First Class

Browser Modes

• headless=True - Browser runs in the background (faster, no UI)
• headless=False - Browser window visible (useful for debugging)

Troubleshooting

Common Issues

Issue: Playwright browser not found

Solution: Run `playwright install chromium`

Issue: Timeout waiting for flight results

Solution: 
- Check your internet connection
- Try with headless=False to see what's happening
- Verify the airport codes are valid
- Ensure the dates are in the future

Issue: No results returned

Solution:
- Verify airport codes are correct (use IATA codes like "SEA", "ICN")
- Check that dates are in YYYY-MM-DD format
- Try different date ranges
- Some routes may not have available flights

Issue: Import errors

Solution:
- Ensure virtual environment is activated
- Run `pip install -r requirements.txt` again
- Verify Python version is 3.10 or higher

Debugging

To debug scraping issues, run with headless=False:

scraper = BingFlightsScraper(headless=False)

This will show the browser window so you can see what's being loaded.

Running Tests

Basic Tests

Run the basic unit tests that verify module imports and URL construction:

python tests/test_mcp.py

End-to-End Tests

Run comprehensive end-to-end tests that perform actual flight searches:

python tests/test_e2e.py

Note: E2E tests make real web requests to Bing Flights and may take several minutes to complete. They include:

1. Invalid Parameters Test - Verifies error handling
2. One-Way Search Test - Real search from SEA to ICN
3. Round-Trip Search Test - Real search from LAX to JFK
4. Multiple Passengers Test - Search with 2 adults and 1 child

The tests use headless browser mode and future dates to ensure valid searches.

Technical Details

Web Scraping Approach

• Uses Playwright for browser automation
• Waits for dynamic content to load
• Extracts data from Bing Flights result cards
• Handles multiple selector patterns for robustness

Error Handling

The scraper uses minimal error handling and allows exceptions to propagate:

• Network errors → Raises exception
• Timeout errors → Raises PlaywrightTimeoutError
• Invalid parameters → Raises ValueError
• Parsing errors → Returns partial results or empty list

This design allows the MCP client to implement appropriate retry logic and error recovery.

Limitations

• Only returns outbound flight details (return flight info not available on Bing results page)
• Maximum results limited by what's visible on the initial page load
• No pagination support (first page results only)
• Scraping depends on Bing's page structure (may break if they change their HTML)

Dependencies

• fastmcp>=0.1.0 - MCP server framework
• playwright>=1.40.0 - Browser automation
• python-dateutil>=2.8.2 - Date parsing utilities
