Connect Windsurf to VariFlight MCP

Set up VariFlight MCP in Windsurf: account requirements, server configuration, authorization, and a flight-query example to verify your connection.

Before you start

Sign in to VariFlight MCP, obtain your MCP Key in the console, and replace YOUR_MCP_KEY in the configuration. Available tools and data depend on your account permissions and the client’s MCP support. Keep the key private.

MCP integration with Windsurf Cascade

Setup steps

1Open the MCP configuration panel and add a custom server.
2Set url and headers.Authorization in mcp_config.json.
3Enable the tools in Cascade and send a query.

[ JSON configuration ]

Configuration file: ~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "variflight-mcp": {
      "url": "https://c-gw.variflight.com/chat_message/mcp/api",
      "headers": {
        "Authorization": "Bearer YOUR_MCP_KEY"
      }
    }
  }
}

[ Verification ]

# Ask in Cascade:
"Compare flight candidates from Beijing to Shanghai tomorrow."
# Candidates and flight status indicate a successful connection.

Verify the connection

Enable the server, start a new conversation, and ask the verification question above. Check that a VariFlight tool was actually called and that the result identifies the flight date and data source. If tools are missing, review the endpoint, Authorization header, account permissions, and your client’s configuration. An empty result is not proof that no flight exists.
