Summary
Connects Claude to the AllFlyghts public API for geo-based flight search. You get three tools: search_locations to find airports and cities, get_city for detailed location data, and search_flights to query routes between any two places. The server is hosted at mcp.allflyghts.com, so you just need to grab an API token from AllFlyghts and add it to your MCP client config. Built in TypeScript with streamable HTTP transport, keeping the API key server-side. Useful when you want Claude to help compare routes, find connections, or answer flight availability questions without bouncing users to a search interface.

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.
Visit for more info: https://www.allflyghts.com/developers/mcp Full docs: https://www.allflyghts.com/mcp
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_KEYPUBLIC_API_KEY_VAULT_URLtogether withMCP_PUBLIC_API_KEY_SECRET_NAME
Optional:
MCP_AUTH_TOKENMCP_AUTH_TOKEN_SECRET_NAMEMCP_SERVER_NAMEMCP_SERVER_VERSIONMCP_TRANSPORTPORTMCP_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.
