AllFlyghts MCP Server

TypeScript MCP server for the AllFlyghts public API.

This repository is a standalone Node.js project. It exposes AllFlyghts data through MCP tools while keeping the public API key on the server side.

Using AllFlyghts via the hosted MCP server

Most users don't need to install or run this code. AllFlyghts runs a managed MCP server.

To use it, configure your MCP client (Claude Desktop, Cursor, etc.) to connect to this endpoint with your AllFlyghts API token in the Authorization header:

Authorization: Bearer <your-token>

Get your token at https://www.allflyghts.com/access/sign-in

This repository contains the source code of that hosted server, made public for transparency. You can also run it locally if you want — instructions below.

Requirements

• Node.js 20+

• An AllFlyghts public API base URL

• An AllFlyghts public API key, provided either directly by environment variable or through Azure Key Vault

Environment

Required:

• ALLFLYGHTS_PUBLIC_API_BASE_URL

Choose one API key source:

• ALLFLYGHTS_PUBLIC_API_KEY

• PUBLIC_API_KEY_VAULT_URL together with MCP_PUBLIC_API_KEY_SECRET_NAME

Optional:

• MCP_AUTH_TOKEN

• MCP_AUTH_TOKEN_SECRET_NAME

• MCP_SERVER_NAME

• MCP_SERVER_VERSION

• MCP_TRANSPORT

• PORT

• MCP_ALLOWED_ORIGINS

If MCP_AUTH_TOKEN or MCP_AUTH_TOKEN_SECRET_NAME is configured for HTTP mode, callers must send:

Authorization: Bearer <token>

Install

npm install

Run

Stdio mode:

npm run dev:stdio

HTTP mode:

npm run dev:http

Production builds:

npm run build

Then start either transport from dist/:

npm run start:stdio
npm run start:http

Notes

• Streamable HTTP creates a fresh MCP server and transport per request.

• Secrets are resolved from Azure Key Vault when configured, with direct environment variables as a fallback.

• Do not commit real API keys, auth tokens, or other secrets to this repository.
