Travel MCP Server

VoyageHacks MCP Server

The official Model Context Protocol server for VoyageHacks.com, a travel publisher with about 680 fact-checked guides in each of 11 languages, covering flights, airline reviews, hotels, destinations, car rental, trains, airport transfers, eSIM, travel VPN, travel credit cards and travel gear.

Live endpoint: https://voyagehacks.com/mcp Version: 2.1.0 Docs: https://voyagehacks.com/en/mcp-server/

Stateless Streamable HTTP transport (JSON-RPC 2.0 over POST, single JSON responses, no SSE, no sessions), no authentication. Any MCP client can connect and start calling tools immediately. A GET returns 405 by design: the server offers no SSE stream, which is what the Streamable HTTP specification asks for in that case.

Listed on the official MCP Registry as com.voyagehacks/travel.

Tools

All twelve are read-only, annotated readOnlyHint: true and destructiveHint: false, and have no side effect outside their response. Each declares an outputSchema and returns structuredContent alongside readable text.

Every vertical tool also returns up to 4 matching VoyageHacks guides in the requested language, so agents can cite full articles alongside the links.

Languages: en, de, fr, es, it, pl, cs, ja, nl, pt, zh. Every tool takes a lang parameter, defaulting to en. Each language is an independently written version of the guide, not a machine translation.

Profiles

The research profile omits get_travel_vpn_links and get_credit_card_links, whose links land on a subscription signup and a financial-product application. It exists for app directories whose guidelines restrict linking to pages that initiate a subscription or purchase.

The guides profile goes further and omits every booking tool, leaving search_articles, get_article, search_travel_gear and recommend_travel_gear. Its only outbound purchases are Amazon product pages for physical travel gear, so it satisfies directories that allow commerce for physical goods only. It also serves its own initialize instructions, which describe the four tools it actually has rather than the full twelve.

Each profile is addressable two ways: /mcp?profile=guides and /mcp/guides are the same handler. The path form exists because the OpenAI plugin submission portal rejects a query string in its MCP Server URL field.

An unrecognized profile, in either form, falls back to the full tool set, so a typo can never silently serve fewer tools than intended.

What it does not do

The server returns published editorial content and search links. It has no live fares, no live room rates, no availability check, no star ratings or review counts, and it cannot make a booking or take a payment.

The travel gear catalog is VoyageHacks' own editorial selection, not a search of all of Amazon. It carries no prices, ratings, review counts or stock: the Amazon Product Advertising API is not enabled for this account, so any such value would be invented. The tools never return those fields.

Limits

About 90 requests per minute per IP, 256 KB per request body, 25 messages per JSON-RPC batch, articles truncated at 60,000 characters. Over the rate limit the server returns HTTP 429 with Retry-After. See SECURITY.md.

Markdown for agents

The whole site is agent-readable, not just this server:

• get_article returns any page as Markdown.
• Any page on voyagehacks.com returns Markdown directly when requested with an Accept: text/markdown header (edge middleware, browsers are unaffected).
• Discovery files: /.well-known/mcp/server-card.json, /llms.txt, /.well-known/agent-skills/index.json, /.well-known/api-catalog, /auth.md.

Transparency

VoyageHacks is an affiliate-funded publisher. Some booking and shopping links returned by these tools are affiliate links (Booking.com through CJ Affiliate, Amazon Associates, Travelpayouts, American Express referral). VoyageHacks may earn a commission from qualifying bookings or purchases at no additional cost to the user.

Every commercial tool states this in its description, and every commercial response repeats it in both its text content and structuredContent.disclosure, so an assistant can disclose it to the end user. The word "affiliate" is kept out of tool name and title values because agents route on those strings and it measurably suppresses selection; it belongs in the description and the response, which is where disclosure obligations actually attach.

Article content is free to read, with no paywall and no authentication.

Self-hosting

This is a Cloudflare Pages Function (functions/mcp.js). To run your own instance:

1. Deploy the functions/ directory with a Cloudflare Pages project.
2. The server reads its content live from the site it fronts: a Hugo build that emits /<lang>/index.json (search index) and /<lang>/gear.json (gear catalog). Point the SITE constant at your deployment.
3. Replace the affiliate constants near the top of mcp.js (Travelpayouts marker, CJ ids, Amazon tag, Amex links) with your own program ids.

This repository mirrors the production function. The only intentional difference is the import on line 37: production imports htmlToMarkdown from the site's _middleware.js, this mirror from its own html-to-markdown.js. If you fork it, keep the affiliate constants in sync with your own site config.
